Gas Bottle Storage Cage Safety Measures

Gas Bottle Storage Cage Safety Measures


Gas tanks, gas cylinders, and gas bottles are widely used in different industrial applications today. They plan an important role in these industries. This is also the reason why proper and safe handling is of great importance when handling, receiving and disposing of gas bottles. Upon receiving a new gas bottle, be sure to inspect it properly and safe to use.

Failure to handle or store them properly can lead to serious problems that can even put the lives of people in danger. There are specific sets of standards that should be followed when handling gas cylinders in order to ensure their safety. One of these standards is the use of a gas bottle storage cage. While they are in storage, the cylinders need to be left loose and should be kept in an upright position. There should be no possibility of tripping over to avoid danger.

The Right Storage

For you to be certain that your gas bottles are properly and safely kept, the right kind of gas bottle storage cage is essential, whether at home or in commercial spaces. Cages are considered to be one of the best solutions for gas bottles. They offer a safe working environment. One important factor to consider when buying one is ventilation. The right ventilation is important to make sure that there is safe dispersal of chemical mists, gases, vapors, and fumes.

In addition, gas bottle cages are a great storage option because these are open, thus there is no risk for any ventilation issue, the danger of falling, and problems with accumulated leaked gases. The ideal structure for this storage has no roof and the doors need to be manufactured from a steel wire mesh.

Handling Practices

In an industrial setting that involves the use of oil and natural gas, safe handling practices need to be a priority. When handling or transporting gas cylinders in an industrial setting, you need to move or transport the cylinders using the right cart or a hand truck.

Gas bottles need to be used, kept, and transported in an upright position. The gas tank needs to be securely fastened and supported by straps, chains, racks, or stands in order to avoid falling or being knocked over.

Storage

Gas bottles require high internal pressure that makes projectiles if stored incorrectly, thus causing valve damage. Gas spills or leaking gas cylinders create an oxygen-deficient atmosphere. Gas tanks should also be stored properly to avoid an atmospheric hazard.

Conclusion

If you happen to be working in an industrial setting or if you are managing an industrial business, be sure to consider safe handling and proper storage of gas cylinders and gas bottles. Following the above-mentioned tips will help lessen the risk of fire or any gas-related accident.

Waterjet Cutting Machine Troubleshooting Tips

 Waterjet Cutting Machine Troubleshooting Tips

Waterjet cutting machines quickly emerged as among the most versatile appliance nowadays. Homemakers are in awe with what this piece of equipment can do for them with regard to extending the shelf life of their highly perishable food items. 

In complete contrast to a thermal cutting method, according to water jet machine manufacturers, waterjet cutters can seamlessly cut through metal without having to leave behind heat-affected zone or HAZ. 

According to water jet machine manufacturers, the manner in which the method employed through the use of waterjet cutting machine works is completely different from how the thermal cutting style is carried out. They can cut through metal without producing or leaving a heat-affected zone or HAZ. This explains the reason why waterjet cutting technology is the method of choice when it comes to cutting, trimming, and shaping metal parts for construction applications and even for aerospace technology, where even the slightest changes in metallurgical attributes could affect the integrity of the material.  

Perhaps the most hardworking of all the components of a waterjet system is the intensifier.  It is comprised of numerous moving parts, and for that reason, there is a higher possibility that something could go wrong at any given time. Common issues encountered here has something to do with over stroking, short seal life, and water leaks. Three other commonly complained issue with an intensifier-based waterjet system is low water pressure, hydraulic pressure failure, and hydraulic temperature overheating. 

Overstroking

There is nothing unusual happening to it if the intensifier would strike faster during startup, as well as when transitioning between high pressure and low pressure. But under normal machine operation, the intensifier is supposed to strike smoothly to the right and left at just about the same speed as on the other.  There are occasions in which the hydraulic piston would travel way faster to just one or even in both directions, sometimes it would even exceed to more than what the pump can support. They refer to this event as over stroking, and would likely trigger the alarm. 

Irrespective of whether you see the overstroking is tending to the right or to the left, or in both directions, the best course of action you need to take is just reset the alarm. 

Regardless of whether the overstroking is tending to the left, to the right, or in both directions, the first thing you should do is reset the alarm. After which you are supposed to

  • Turn the cutting head off. 
  • Turn on the pump and let the pressure build-up on its own.
  • Now you can turn the cutting head-on. 

Keep an eye on the intensifier stroke rate using the operator interface indicator or you can manually monitor instead of the proximity switches.

Water Leaks

Another area of concern in most waterjet cutting machine is water leakage. If there is a visible water drip after every few strokes, take this as an indication that your seals are coming so close to the end of their service life. With that, you need to have a spare so you can immediately replace them, just in case. 

Should there be an obvious drip after every stroke, that calls for you to change the seals at the soonest possible time? If you have observed leaks in some other areas, take that as an indication of a worn part, damaged seat or loose-fitting. 

Presence of leaks calls for your immediate attention right away so as to prevent the nearby components from getting damaged too. You need to keep an attentive eye on the following: 

Water leaks from the cylinder end mean that the high-pressure seal from that end has failed. 

  • If there are hot water leaks from the end cap, take this as an indication that the cylinder’s static end has failed, and thus would be needing replacement. 
  • Check out for cold water leaks from the end bell, you may take this as a sign that the O-rings pointing inlet water towards the cylinder bore has just failed and thus would be requiring replacement. 
  • Check out for the weep hole’s warm water on the check valve, it might be a sign that your output adapter is loose or that your high-pressure poppet seat failed. It might also mean to say that the check valve’s seat has just cracked.  

These troubleshooting tips will help save you more money and time on a service technician, which in a way helps you to optimize your profits.

Package Your Access Food with a Vacuum Sealer

Proper food preparation practices are among the major elements of cooking while having a dependable vacuum sealer to help package your access food is imperative. By selecting the right kind of food sealer for home use, anticipate that this addition to your arsenal of kitchen tools will have a significant impact on your food preparation time. This means to say that your stress level you have in your kitchen area will ebb away.

Package Your Access Food with a Vacuum Sealer

Later on, you might need to stock up on various kinds of food sealer bags initially or look up for some food containers accessories, too.

By far, one of the most used pieces of equipment in a modern-day kitchen is the vacuum sealing machine. From beans to chicken soup and vegetables, even to your fine cooking pleasures, you will find that you need to make use of vacuum sealing help every now and then.

Most of these food sealers available in the market today come with food feature automatic handling. This means to say that there is no need to concern yourself about figuring out the correct pressure that your food item requires.  

Cooking your food for each meal every single day is fairly easy to do, but when it comes to saving the leftovers this is where the challenge comes in.  It can never be a tough call to choose between just the right amount of items for your kitchen, simply because buying more will help you save more. Besides, that practice will also save you valuable time going to and from the market just to one to several items you need.

When trying to shop for a vacuum sealer, there are a few basic things you need to go by. These pointers below will help you find the right vacuum sealing machine for the job:

  1. Sealing

The most important factor to look into when shopping for a vacuum food sealer is their sealing quality. Keep in mind that the main purpose you are buying such a piece of equipment is for sealing, therefore it just makes perfect sense that you initially check out this factor first. If ever this area is flawed or is not working right, it runs the risk of your food item getting exposed still to the elements, moisture, oxygen, and many other particles — then it might still get spoilt in a snap.

2. Material Density

If it is typical for your household to have tons of highly perishable food items that you need to store for later use or consumption, then it makes sense that you stock on covers or food sealing bags that are quite thick and durable, too. Personally, I would go for something that is dense. This type of food vacuum sealing bags assures your food extra protection.

3. Type of sealing

There are many different types of vacuum sealers, and they can be practically applied either for commercial or residential use.  Some of them are in the form of bags or covers while others as a bottle or jar stop and a few others as rolls and zip-lock patterns.                     

Carefully choose the sealing type that will best serve your purpose and needs. If you’re needing one for domestic use, try to look for basic models. They deliver the job just fine. But if you are intending to have it for commercial purposes, it is more practical to search for models that are quite bigger than the ones intended for home use. Ensure also that they do have lots of useful functionality that you can take good advantage of.

4. Frequency of Use

In your estimation, how often would you pull out your vacuum sealing machine? Whatever your honest to goodness answer to this question is, it would determine the type of machine you will need to acquire. If you are thinking that you might be using your equipment several times a day and that you would be disposing of the bags after one time use after taking out the food you stored in them, you might as well consider purchasing smaller pieces of bags instead.

You can also reuse the bags, but for this, your best option would be to look for zip-lock pouches. So far, they are more cost-effective and more durable than others.  

Conclusion

Vacuum sealers are indeed one of the most ubiquitous appliances in any modern kitchen today. Homemakers can’t be more effective in their absence due to the fact that they are very indispensable in storing up pasta, greens, delicate fruits, many other highly perishable food items. However, you need to know how to identify the right piece of equipment for the job. This will help put more value to your money.

Blood testing will help your physician carry out the necessary steps to measuring your testosterone. Besides that, there is no other way you can know.

Subtle Symptoms of Low Testosterone Level

There are occasions that symptoms following a drop in testosterone levels are sometimes very obvious to see, but sometimes also they are very subtle. As men advances in their age, their testosterone level will decline gradually, and the symptoms that this come can be observed. Some of these symptoms would include any or all of the following:

  • Decreased interest in sex ( low libido)
  • Erectile dysfunction or inability to have and sustain one.
  • Poor energy level
  • Easily fatigued

TRT Replacement Treatment Options

A therapy program for testosterone replacement normally comes in many forms. Regardless of how you want to do this treatment, the end-goal would always be one and the same, and that is for your body to have a higher concentration of testosterone.

Implants and Injections

You can be injected with testosterone and they are administered directly into your muscles. As for the implant option, this can be carried out by implanting pellet-containing testosterone into the soft tissues of your body. Consequently, your body gradually absorbs them into your bloodstream.   

Mouth Patch

This comes in the form of a table that lodges itself to your upper gums, right above the incisor.  You can apply them twice a day and will continuously release testosterone into your blood by virtue of oral tissues.

Testosterone Gels

Testosterone TRT replacement gels can be applied on the skin surface once a day and can be absorbed directly through it. Another option is the Natesto gel, you can apply this right inside your nose.  

Expert minds in the medical field have expressed fears that orally administered testosterone supplements might have an adverse impact on the liver. They seem to be favoring other methods like gels and skin patches instead. Hence, bypassing the liver so much so that testosterone gets into your bloodstream directly.

3D Printing and Its Educational Uses

3D Printing and Its Educational Uses

When someone claims to have a 3D printer, people would visualize it to be a machine that is capable of producing 3D printed images on a piece of paper. But in reality, 3D printing is more than having an image on a paper, but it can bring an object to life. The printer replicates the image layer by layer with the use of CAD programs. Any kind of creation that is made through a supported design program could be brought to the real world.

What is more amazing is the fact that the use of a 3D printer has been very beneficial in different fields, especially in the field of education.

Biology

Do you need to do a cross-section of a heart for the students to study with? Maybe you need a few for the entire class? With 3D printing, it is possible to replicate as many of them with great details.

Geography

Today’s technology allows us to graph contours for landscapes. By simple importing the contours and images into the program, geography classes would be able to have a detailed terrain map of the area that they are studying.

Drafting

After having the initial drawing of a building, an impeccable 3D creation could bring any art into reality. Any shape and design used to make vehicles of different types in a drafting class can lead to more inventive ways to keep the students on their task.

Graphic Design

As students make masterpieces for the classroom, a 3D printer could turn them into a reality. Any shape and design that they can imagine could be created in real-life. Video game characters, models of creatures, special effect, and so many others can be created to increase their presentation value for graphic design.

History

Imagine having a scale accurate model of pivotal points in the most historic battles. With the help of a 3D printer, rendering a tectonic plate movement can help assist students in getting a good grade on their history report. They can even reduce the size of dinosaur bones for them to better demonstrate their features in the most detailed way.

Artifacts

If only they have access, there are so many things in this world that people, specifically students, could learn. With the use of a 3D printer and a CAD program, such things could be created for different purposes. Almost anything can be created as long as there is a 3D rendering program.

The possibilities and benefits that a 3D printer could offer to people in the field of education are countless. This is also the reason why more and more schools are starting to implement the technology for a better learning experience that will be of great use for the students now and in the future.

Benefits and Applications of Sonic Drilling

Benefits and Applications of Sonic Drilling

Sonic drilling works by using resonance energy. Its drill head sends high frequency vibration to the drill string or pipe up to the drill bit.  The drill rig operator can control the frequency of the vibration, depending on the type of rock or ground being drilled. The resonance frequency is usually between 50htz and 150htz. This resonance causes the rock or ground to become fluid-like at the surface of the drill.  The same as when you cut a hot knife through butter that is cold, sonic drilling significantly decreases friction. This allows drilling to be five times faster than other traditional drilling methods. This technique of reducing friction eliminates the need for using mud or lubricants while drilling. Sonic drilling only needs compressed air or water for flushing the cuttings. Sonic drill rigs can drill for up to 100 meters or 300 feet deep.

Sonic Drilling Benefits

Sonic drilling is more eco-friendly compared to other conventional drilling techniques. Unlike other drilling methods that use mud or lubricants, sonic drilling only takes compressed air or water when flushing the cuttings to the surface. This technique reduces possible contamination especially in sensitive environments. Overall, sonic rig drilling produces less waste. This drilling method is also more efficient because of its reduced friction, speeding up the drilling process. Moreover, with sonic drilling, you’ll have minimal disturbance or impact to the environment, which also means cleaning up the site is much faster and easier.

Sonic drill rigs are typically smaller machineries that use less horsepower. Less power needed means lower fuel cost. Its efficiency and lesser on-site waste means lower operational and labour costs as well. What’s also great about sonic drilling is that the drill rig operator can easily adjust and control the vibrational frequency to suit the type of ground or rock.

Sonic Drilling Applications

Sonics drilling is ideal to use in environmentally sensitive environments because it operates with reduced disturbance and contamination. Because drilling process is faster, the time spent in these sensitive areas is reduced. Sonic drilling is a great option for drilling places with difficult terrain because of its ability to change and adjust vibration frequencies, matching to the type of soil or rock. Conventional drills would be stuck in these types of environments, but not sonic drilling.

Sonic drilling is also the best choice for geothermal installations, as not only it can drill, but it can also case, and install loop and grout. Sonic drilling can do all of this in one operation for geothermal heating. Another application of sonic drilling is for environmental investigations. It can drill through landfill debris and able to take water or core samples no matter the depth. Sonic drilling is used in organic, heavy metal, and other types of contamination investigation. Moreover, this type of drilling method is applied in mineral exploration. If you are into geotech drilling and exploration, sonic drilling is the best option. It can take continuous core samples that are of high quality. The holes it drills are much straighter than traditional drilling.

The History of Waterjet Cutting and Its Uses

You might have come across with the term waterjet one way or another, but you may not really know what it is. It is not just a stream of water shooting out at a very high pressure, but there is much more to it. Imagine how water could cut through almost any type of material when it is pressurized and is controlled in a certain way.

Water may appear to be very gentle and soft, but it is one of the most powerful forces of nature. Just imagine how the waves of the sea could carry you at the beach or how it could smash against the rocks at the shore, washing away huge boulders and eroding the mountainsides. Think about how devastating a flood could be.

Even water from a garden hose has a certain force to it. Think about the pressure of the water from a garden hose. Imagine that pressurized water being pushed at a higher pressure through a smaller hole. This pressurized water with a mix of abrasive grit is a cutting tool that you should not underestimate. It is the most versatile and precise cutting method for many types of materials, from the super soft fabrics and foams to the hardest metals like titanium.

 

How it started

The idea of water jet cutting came from erosion. This method of precision cutting started in the 1800s. Hydraulic coal mining was very popular in these times in areas like the Soviet Union and in New Zealand. Water from stream are used by miners to blast over solid rocks. This erosion process carries loose rocks along with coal.

Between 1853 and 1886, miners during the California Gold Rush used pressurized water in excavating mines for soft gold rock. This was the first time in which the power of pressurized water was tried. This technique was also for the safety of the miners. In the 1900s until 1930s, this method was used in Europe and in Asia. Cutting rock with the use of pressurized water was first attempted by Russians.

It was not until the 1970s when the technology of waterjet cutting was first developed. The first industrial cutter was introduced in 1972. Further developments such as the abrasive waterjets were done in the 1980s. Abrasive waterjets is the same as the pressurized water, but an abrasive grit is added to the steam of water. This development increased the cutting power of waterjet, which enables it to cut through a range of different materials.

 

Waterjets on the market today

Today, you will find different types of waterjets, including percussive jets. This technology to cut materials uses rapidly pulsing jets. Another type of waterjet is the cavitation jets, which by high forces of water forms empty cavities, which would then collapse immediately. The hybrid jets are also popular waterjets, which involves pairing of waterjets with plasma, lasers and other cutting methods.

The Proper Way to Clean Glass Pendant Lights

Aside from being attractive decorations and changing the ambiance of the home, lights provide illumination to an area making it more functional. The best thing about them is that they come in various shapes and sizes, offering us options for decorative applications. One of the most popular types is glass pendant lights. These fixtures are attached to the ceiling using a chain or steel cable. They may also have hand-painted shades or are decorated.

Such lighting fixtures are so attractive and functional at the same time, but just like with your other things at home, they too, need to be maintained. The dirt on your glass pendant light can decrease its brightness and even reduce its aesthetic appeal. Therefore, you need to clean them before they become too grimy. Below are some steps you can follow to properly clean your lighting fixture.

Take Precautions

Before you do any work with your glass pendant lights, you have to ensure that you have turned off your power supply or else you will be electrocuted. Also, if you are living with other people, ask them not to turn the power on. When using a ladder, place it on an even surface so it becomes easier for you to reach your lighting fixtures. Do not forget to wear a pair of gloves when cleaning the fixtures to avoid any allergic reaction from your cleaning products.

 

Dismantle your Lighting Fixture

Various companies assemble lights in different ways. This means that to dismantle them will also differ. However, the most common process would follow the following steps:

  •         Remove the bulb before working on shade removal
  •         To take the shade, use a screwdriver or you can unclip the holders that hold the shade

Clean your Pendant Lighting

This step will greatly depend on how dirty the shade is. Generally, you can mix water and liquid soap for cleaning. Make sure that soak the shade in the mixture for at least 10 minutes then remove it. If your shade is hand-painted, avoid using abrasive cloths for drying or cleaning. You should never use a dishwasher as it can be very strong for the shade and may break it.

After 10 minutes of soaking, remove the shade and buff it with a clean cloth. You may also use a glass cleaner to do this. If your fixture is grimy, use a grease remover as the mixture of soap and water may not work well in removing the thick grease. You can also use a wet cloth to clean the bulb that you have removed. Wipe it clean to increase its brightness.

 

Reassemble your Pieces

After you have dried the bulb and shade, install them again. Check if your ladder is well-placed and the power source is off. When you are done installing them, step away from your fixture and turn it on. If it fails to turn on, check if it is properly fitted in the socket.

Cleaning your lighting fixture properly is the key to make sure that it lasts for a long time while providing illumination and adding beauty to the area.

 

Useful Tips for Air Compressor Repairs and Maintenance

When it comes to air compressors, in order to secure efficient operation, proper maintenance is needed. This will also reduce operational costs and extend the life the life of the air compressor. Otherwise, malfunction will happen and eventually the air compressor will break down, which will be very costly not only on the repair part but the loss of production as well. Below are some air compressor repairs and maintenance tips that you can apply to avoid these things.

 

Owner’s Manual

It is very important that you read, understand and follow the manual on how to properly use and take care of your air compressor. Although it is reliable equipment that does not require so much maintenance, user’s manual can be of help in case a problem arises. If lost it, you can download them online or call the customer service of your manufacturer.

 

Inlet Air Filter

The majority of air compressors come with inlet air filter. This makes sure that the compressor gets clean air and acts as a silencer or muffler. The inlet air filter should be regularly checked to ensure cleanliness. In case of clogs, it can cause higher electricity consumption and lower operational efficiency.

 

Tighten the Fasteners

Whatever the type of the compressor is, they all produce vibrations when they are running. Although a rotary compressor may produce a lower vibration compared to a reciprocating type, they all need to be inspected on a regularly basis to make sure that the nuts and bolts are not loose. Tighten them up if you have found them loose.

 

Lubrication

Lubrication is a must to ensure smooth operation and so you can avoid air compressor repairs. The lack of proper lubrication can cause excessive wear which will eventually lead to break down of its parts. Make sure that you use the right amount of oil as per the recommendation of the manufacturer. In addition, you also need to check the oil level and refill it up if necessary.

 

Safety Shutdown

There are a lot of industrial compressors installed that come with built-in safety down features. The purpose of this is to shut off and to protect the compressor in case the operating limits are exceeded. This may include high temperature, low oil pressure, higher current and very high pressure. Doing a safety check will guarantee that the safety systems are functioning and the equipment is well protected.

 

Heat Exchangers

A heat exchanger is necessary in order to reduce air temperature, as well as the operating temperature of the air compressor. If your compressor has a heat exchanger, clean it regularly. The scaling that results from cooling water can cause the exchanger to clog which will reduce its heat transfer capability. Periodic cleaning and descaling is necessary to reduce its operating temperature, while increasing its life expectancy.

By simply performing these maintenance tips for your air compressor, you need not worry about unnecessary costs. At the same time, you can maximize the use of your machine for a longer time.
