Product Description

Classification of expansion bellows 

Expansion Joint SS is devided into two connection ways of flange and welding, buried pipe compensator commonly used welding methods (except trench installation) .

Different models of stainless steel metal bellows expansion joint

  

Working theory of expansion bellows 

metal expansion joint is a compensator device which absorb the size change of pipeline, conduit or vessel caused by thermal expansion and contraction and other reasons, by using the effective extension and deformation of elastic elements of bellows compensator. It belongs to a compensation element, it can absorb axial, transverse and angular displacement.

Characteristics of expansion bellows 

metal expansion joint (Metal corrugated compensator) has excellent flexibility, light weight, corrosion resistance, high temperature resistance and high pressure resistance, it can be connected in any direction of the pipeline, it can play a role in temperature compensation, absorbing vibration, reducing noise, changing the conveying direction of medium, it can eliminate the mechanical dispalcement between pipes, between pipe and equipment, double flange metal corrugated pipe is particularly applicable for various pumps, valves and flexible joints which has a certain displacement and vibration .

 

Material of expansion bellows 

metal expansion joint is manufactured by adopting stainless steel material or according to the materials customer requested. Different metal materials are chosen for their different uses.
