Choosing a pneumatic hose is very important for our needs,but how to select? ORIENTFLEX will give you a full analysis!
How to choose the hose material?
There are a few materials for the hose:
1.Polyurethane
Polyurethane is a popular choice of material, as it’s quite strong, flexible and resistant to abrasion and kinks. It’s also strong enough to handle contact with oils and fuels. This material is often used in vacuum equipment, medical and laboratory settings, semiconductor manufacturing and pneumatic actuation systems.
2.Nylon
Nylon is used as a material for tubing as it’s relatively light, yet dimensionally stable and tough. Tubing made up of nylon is often selected in applications where withstanding high pressures is important. It also offers greater flexibility, allowing it to be routed through tight spaces, low water absorption and high resistance to flexural fatigue.
3.Polyethylene
Polyethylene tubing is regularly used for pneumatic controls and other low-pressure applications. It offers good resistance to a wide range of solvents and chemicals, is flexible and relatively affordable when compared to other materials. Semi-rigid HDPE tubing is available, which is more resistant to damage and has a higher burst pressure when compared to ordinary polyethylene tubing.
4.Polyvinyl Chloride (PVC)
PVC tubing offers superior flexibility and lighter weight compared to polyethylene and nylon. It can resist exposure to chemicals and can withstand repeated sterilization procedures. This is why it’s often used in medical applications, as PVC tubing can be manufactured to meet all FDA specifications for contact with food and drug products. This type of tubing is usually made clear, making it an optimal choice for settings where seeing the flow is needed.
5.Polypropylene
Polypropylene tubing is commonly used in food manufacturing. It has excellent resistance to chemicals and is well suited for outdoor applications as it’s able to withstand UV radiation without degrading.
Any engineer comparing materials should carefully assess the different benefits and drawbacks that each of them comes with. The chosen material should be compatible with the fluids that will go through the conduit. So we need to think a twice before buying pu hose.
Pneumatic tubing and hose assemblies use various fittings to connect them to mating components. These can be made out of many different materials, such as stainless steel, plastic or brass. The chosen type and material of fittings should be compatible with the hose use.
