High pressure flexible ptfe coupling corrugated expansion joint
Feature
The lining material PTFE is also called , 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.
PTFE corrugated bellow expansion joint with flange
1.Flexible joint with PTFE inner
2. Have excellent dielectric and chemical corrosion-resistance;
3. Non-absorbent, non-stick, non-conductive, low coefficient and
non-aging properties
4.For oil, chemicals, food, medicine, space, and other fields.
