PTFE bellows compensator or corrugated pipe is usually used in conveying system applicable for various corrosive gas or liquid, aiming to solve the compensation of thermal expansion & contraction and offset the installation deviation in the pipeline; or by way of flexible connection, to improve the mechanical damage arisen from the mechanical vibration between the inlet/outlet of fan & pump and pipeline.

Product Category

A) Ordinary type: PTFE bellows compensator made from pure PTFE (Type I) or composite elementary unit (Type II) of PTFE & synthetic rubber, and reinforced with high-strength spring steel.

B) stainless steel compound: PTFE bellows compensator made from PTFE & bellows stainless steel sleeve.

C) stainless steel netting compound: PTFE bellows compensator compound from PTFE & bellows stainless steel net.

D) Vacuum type: made from both of Category A, B and adds a PTFE-lined calibrating ring in wave peak for preventing from vacuum suction.

Properties of product

A) Without special requirements for connection flanges, comply with HG/T20592 PN1.0MPa standard.

B) The thickness, operating temperature and applicable media are similar to those of pipeline.

C) As used for large-diameter compensator (DN>30mm), vacuum type is preferred.

D) The wave number is generally as 3, please customized for extension or non-standard products.

E) Please find the structural length and technical parameter of the compensator in the Table.
