PTFE Rubber Expansion Joint

PTFE rubber expansion joint


● List of main components and materials

1,Inner and outer rubber: ethylene propylene diene monomer (EPDM), natural rubber (NR)

2,Main frame: polyester cord

3,Booster ring: multi strand wire rope

4,Flange material: stainless steel (201, 304, 316, 321)

5,Lining material: PTFE

PTFE is added to the inner part of the rubber flexible joint with PTFE flange lining on the basis of the original rubber flexible joint or EPDM high abrasion resistant rubber flexible joint TEFLON polytetrafluoroethylene coating is mainly white, which can effectively protect the rubber soft joints from being eroded by corrosive media, such as strong acid, strong alkali or high temperature oil. The flanges are made of stainless steel flanges. The original mechanical and physical properties have not been affected at all, and they can still compensate for pipeline vibration, absorb pipeline displacement and reduce pipeline noise.




Advantages of PTFE

High temperature resistance - operating temperature up to 250 ℃.

Low temperature resistance - good mechanical toughness; The elongation of 5% can be maintained even if the temperature drops to - 196 ℃.

Corrosion resistance: It is inert to most chemicals and solvents and can resist strong acids and alkalis, water and various organic solvents.

PTFE pipe

Weather resistance - the best aging life of plastics.

High lubrication is the one with the lowest friction coefficient among solid materials.

Non adhesion - is the minimum surface tension in solid materials, and does not adhere to any substance.

Toxic free: It is physiologically inert and can be implanted into the body as an artificial blood vessel and organ for a long time without adverse reactions.

Electrical insulation - It can withstand 1500 V high voltage.
