FEP bellows common specifications and main application scenarios
What is 1. FEP bellows?
FEP bellows is a tubular elastic sensitive element, which is made of foldable corrugated sheets connected in a specific direction, showing good telescopic performance. The design of the bellows is characterized by its thin and light wall, so it has a high sensitivity and can cover a wide measurement range from tens of Pa to tens of MPa. During use, one end of the bellows is fixed, and the other end remains free, and its elasticity is enhanced by an auxiliary coil spring or reed. When the pressure inside the bellows, it will stretch along the length of the tube, resulting in a displacement proportional to the pressure on the active end. This displacement will then drive the pointer to move, thus directly indicating the magnitude of the measured pressure. However, because the bellows needs a large volume change during the expansion process, its response speed will be slightly slower than the Bouton tube, so the bellows is more suitable for low-pressure measurement occasions.

3. FEP bellows main application scenarios
In the chemical industry, FEP bellows have excellent chemical stability, so they are often used to transport a variety of chemical liquids and gases.
In the electronics industry, FEP corrugated pipe because of its excellent insulation performance, mainly used in wire and cable protection and packaging, as well as circuit board insulation work.
In laboratory applications, FEP bellows are often used for the transportation of chemical reagents, the connection of experimental equipment and the assembly of chemical evaporation systems because of their transparency and corrosion resistance. At the same time, it is convenient for laboratory personnel to visually observe the fluid dynamics in the tube.
In the food processing and beverage industry, FEP bellows are also widely used in the transportation of liquid, gas and other food raw materials and finished products due to their safe and hygienic characteristics.
In the field of medical equipment, FEP bellows are widely used in medical catheters and instruments due to their biocompatibility and corrosion resistance.
In addition, FEP bellows also play an important role in special occasions, such as as tubular reactors and exchangers, as well as tankers, storage tanks, containers and reactors to the discharge tube. At the same time, it can effectively replace graphite, ceramic, glass and other pipes with low mechanical strength, and is used for pipeline dislocation connection or balance pipeline displacement and dimensional changes caused by climate or other reasons, and eliminate high-frequency mechanical vibration.
