We can produce 3 types of PTFE Expansion Joint it can also be called PTFE Bellows, namely:
PTFE Expansion Joint, PTFE Metal Expansion Joint, PTFE Rubber Expansion Joint
PTFE Expansion Joint has a structure with a reinforce ring as a bellows retainer on PTFE, can use Carbon Steel or Stainless Steel for the flange. PTFE it is suitable for use with all chemical products and compensates for repeated thermal expansion in pipes. It can withstand various concentrations of acids, alkalis, and salts, and has the advantage of pressure on PTFE stainless steel expansion joints.
The Expansion Joint outer body is a stainless steel metal that combines the properties of metal and PTFE into the most advance on the market. There is additional Types of Expansion Joints like Lined, Hinged, Dual and Universal Tied.
PTFE metal expansion joints can be manufactured in special lengths and in special movement capabilities (according to requirements). Consult for information on the specific construction you need for your application.
Rubber expansion joints with PTFE are designed similarly to other types, namely to reduce piping pressure, absorb pipe misalignment, compression and extension, noise and vibration, in a relatively short space of time. But this item has better flexibility at a lower price.
Material : EPDM, NBR, Viton
