Thin Wall Stainless Steel Tubing Uses the Same Gauges as Other Stainless Steel Tubing

Not only is it important to select the right gauge but also the right wall thickness when using stainless steel tubing. For instance, thin wall stainless steel tubing with a gauge size of 12 has the same otter diameter of regular wall and extra thin wall tubing. The difference has to do with the inside diameter being slightly larger than regular wall and slightly smaller than extra thin wall tubing.

Use Thin Wall Stainless Steel Tubing When You Want to Change Fluid Flow Rates

The wall size is important when you want to use a set gauge of tubing and need to increase or decrease the flow rate of fluid through the tubing. If you are using extra thin wall and the fluid is flowing through too fast, you should try using thin wall stainless steel tubing to decrease the flow rate. On the other hand, if you are using regular wall tubing and the fluid is passing through too slowly, thin wall tubing will help increase the flow rate.

Fluid Filtration Is a Common Use for Nylon Mesh Screens

One of the more common uses of nylon mesh screens is for fluid filtration. As liquids pass through the mesh screens particles of various sizes are removed from the fluid to make it as pure as possible. The amount of particle removal is dependent upon the actual size of the mesh openings and other processes used during filtration. It is possible to use multiple mesh screens at several stages where openings become smaller and smaller to increase the rate of particle remove from the liquid.

Inspect and Replace Nylon Mesh Screens to Maintain Desired Filtration Levels

Over time and exposure to various types of fluids it is often necessary to replace your nylon mesh screens. This is because certain kinds of chemicals, acids, and other liquids can cause the mesh materials to break down. While the screen might look intact, you may discover from closer inspection certain areas where the openings are no longer held securely together. As fluids pass through these sections the mesh will fail to properly stop particles from flowing through the screen. By inspecting screens on a regular basis you are able to replace them as needed and are able to maintain your desired filtration levels.

PTFE Tubing Is Not Designed to Be Shrunk like PTFE Heat Shrink Tubing

It is important to remember PTFE tubing is not the same thing as PTFE heat shrink tubing. While both products do use Teflon® in their construction they perform and behave differently. Heat shrink tubing will reduce in size around the items where it is being applied once it reaches the correct shrinking point. Regular Teflon® tubing on the other hand is not designed to be shrunk and maintains its size, as long as it is not exposed extremely high temperatures above 635 degrees Fahrenheit.

Some Applications Combine PTFE Tubing with Other Materials to Create Finished Goods

You can use PTFE tubing by itself or along with other materials with the production and manufacture of your finished goods. For instance, you are able to pass hypodermic tube through the interior of Teflon® tubing to create wire guide assemblies. You could also run electrical wiring through the interior of the tubing to increase the amount of insulation or to protect the wiring from deteriorating from exposure in corrosive environments.

The Automotive Industry Uses Hypodermic Tubing

One type of business where you often find hypodermic tubing being used is the automotive industry. This type of tubing is used to deliver the precise amount of fluid materials to different locations during vehicle assembly processes. For instance, glues and adhesives used to secure windshields in place have to be accurate. If too little adhesive is applied the windshield will not be secure. If too much adhesive is used it flows out of the seams and lower the production quality of the vehicle.

Furniture Manufacturers Are another Industry Which Uses Hypodermic Tubing

Another business which uses hypodermic tubing for applying fluids is furniture manufacturers. Building furniture uses all types of glues, adhesives and lubricants. For example, office chairs on wheels may use small ball bearings packed in grease within sealed wheel housings. The grease helps to keep the ball bearings lubricated while allowing you to easily move the chair from one location to another.

Teflon® Heat Shrink Tubing Is Also Called PTFE Shrink Tubing

Teflon® heat shrink tubing is another name given to PTFE shrink tubing. Teflon® is the brand name given to polytetrafluoroethylene which is a synthetic material. Specifically, PFTE is a fluoropolymer made from tetrafluoroethylene. Teflon® has several properties that make it an ideal product to use in a variety of applications. The tubing does require heating it to the correct melting temperature in order to shrink the tubing firmly in the locations where it is being applied.

Teflon® Heat Shrink Tubing Has Many Useful Purposes for Various Industries

A variety of industries have useful purposes and applications for Teflon® heat shrink tubing. This type of tubing is used as an insulating material for electrical wiring and is often used as part of manufacturing process to create bundled wiring harnesses. PTFE tubing can be used to create a barrier against chemicals, corrosions, bases, acids, and moisture. You are also able to use this tubing for increasing the amount of resistance against shock and strains created by moving components within various products.

Filtration Systems Often Include Woven Nylon Mesh

Filtration systems rely on the ability for liquids or air to be able to pass fully through the system. As the liquid or air enters the system it often passes through a series of different filtration stages. At each stage different impurities, particles, dirt, and debris are removed. In order to promote the flow of liquids or air through the filtration system it is common to use woven nylon mesh. The openings in the mesh do not restrict the flow of fluids or air, while at the same time help to remove particles of different sizes.

Inspect Woven Nylon Mesh in Filtration Systems on a Regular Basis

In order to maintain the desired level and results when using filtration systems it is important to inspect them on a regular basis. You will find woven nylon mesh screens within the system can become clogged with particles overtime. You may be able to clean the mesh screens by spraying them out with water. In cases where the sediment is still blocking mesh openings it is better to just replace it with new nylon mesh.

You Can Purchase Blunt Needles in Different Lengths and Gauges

Blunt needles are the result of combining hypodermic tubing and polypropylene luer hubs. These needle assemblies are available in different gauge sizes as well as needle lengths. The gauge and length you require does depend upon the actual types of applications. For instance in healthcare, some needles are used to make injections, others to draw blood, and still others for surgical procedures. Each of the needles will be different lengths in order to be able to reach the desired area of the body where they are used.

Not All Blunt Needles Are Finished with Straight End Blunt Tips

Special finishing processes are able to be applied to blunt needles for situations where a straight end tip will not work correctly. Blunt tipped needles can be angled at varying degrees to create a curved tip. The amount of angling required is dependent upon where and how the needle is used, as well as the application. Two examples of possible angles achieved through finishing processes are 45 degree angled needles and 90 degree angled needles.

Bundle and Hold Wires in Place with PTFE Heat Shrink Tubing

Bundling wires together can be accomplished by using PTFE heat shrink tubing. The process could involve cutting piece of tubing to size and first applying it to the individual wires. Once each wire has its own tubing on it, they are able to be held together and in place by using a larger piece of tubing and shrinking it around the group of wires.

Make Sure to Fully Shrink PTFE Heat Shrink Tubing on All Sides

A heat gun is commonly used to provide the necessary heat required to shrink PTFE heat shrink tubing. You need to make sure to evenly apply the heat by moving the gun back and forth to all sides of the tubing in the location where the tubing is placed. If the tubing is not shrunk correctly there could be sections of the tubing which do not seal fully. In situations where the tubing needs to be applied in tight locations you will want to remove the wire or cable, apply the tubing and then reattach it.

Polyester Mesh Is Better Suited to Some Applications Due to Its Properties

The types of properties found in polyester mesh make it more suitable for certain applications than polypropylene or polyamide mesh. For instance, polyester has a higher softening point and melting point than the other two kinds of mesh. Polyester also provides better light and weather resistance when used in outdoor settings or locations which receive direct sunlight.

Polyester Mesh Is Designed for High Acidity Levels and Water Filtration Systems

You should consider using polyester mesh in water filtration systems. Polyester is able to stand up to wet conditions and water better than nylon mesh. While nylon mesh can also be used for water filtration systems, it has to be replaced more frequently than polyester. You should also consider using polyester in cases where you are working with liquids with high acidity levels or if the water being filtered contains high acid levels. Polyester is also more resistant to acids than nylon filter mesh.
