Product Description

The PTFE bellows compensator is used to compensate the thermal expansion and contraction of the pipeline system with the strong corrosive medium. According to the different structure, it can be divided into three categories: I class is PTFE compensator, II class is PTFE outsouring rubber reinforced compensator, III class is PTFE outsourcing metal strengthened compensator. Because of its chemical corrosion resistance and excellent dielectric properties (except Fluorine under high temperature and molten alkali metal), Non absorbent, not sticky, not conductive, low coefficient of friction performance, PTFE bellows compensator is widely used in chemical, petroleum, textile, pharmaceutical, metallurgy, machinery, electronics, electrical appliances, electric power food, aviation, military and scientific research and other industries.

The lining material PTFE is also called Teflon, 4F, the King of Plastic. PTFE has excellent acid and alkali resistance property, and it is resistant to all kinds of organic solvent, high temperature resistance, low friction coefficient, can be used for lubrication or coating. PTFE is the best quality corrosion resistant material in the world. It can working under +250℃ to -180℃ for a long time, almost resistant to all chemical medicine.

Product Features of PTFE Bellows Compensator:

  1. High temperature resistance, working temperature can reach 250 ℃.
  2. Good low temperature resistance, good mechanical toughness; Even if the temperature dropped to - 196 ℃, it can also maintain the elongation of 5%.
  3. Corrosion resistance-to most chemicals and solvents, inert, acid alkali, water and a variety of organic solvents.
  4. Weather-proof, service life is the longest.
  5. High lubrication - the lowest friction coefficient in solid materials.
  6. Inadhesion - the surface tension of the solid material is is the smallest, don't adhere to any material.
  7. Non-toxic, has a physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reaction.
