What is the relationship between the pressure resistance of Air hose and its material?

The pressure resistance performance of Air hose is directly affected by its material. Rubber is a common material for making hoses. It has good elasticity and softness and is suitable for low to medium pressure gas transportation. Polyurethane is the choice for high-pressure applications due to its excellent wear resistance and strength, making it suitable for medium to high-pressure gas transportation while being relatively lightweight. PVC is an affordable option for low to moderate pressure applications, but may be relatively poor at high temperatures and abrasion resistance. Nylon is lightweight, high-strength, has good abrasion resistance, is suitable for medium-pressure applications, and has some resistance to chemicals. The air hose with polyester braided structure has high strength and pressure resistance and is often used for higher pressure gas transportation.

When selecting an Air hose, factors such as gas characteristics, working environment, operating pressure, and wear resistance need to be comprehensively considered. Different gases may have different corrosiveness and permeability to materials, and factors such as temperature, humidity, and chemical exposure in the working environment will also affect the choice of materials. According to the working pressure requirements of gas transportation, select a material with suitable pressure resistance, and consider the friction and wear that the Air hose may suffer during use, and select a material with good wear resistance.
