Detailed descriptions of Bellows Coupling

Brief introduction:
Stainless steel bellows expansion joint is also known as expansion joint or expansions bend. The main body is the bellows (a flexible element), and it is also composed with some accessories like side tubes, brackets, flanges and conduit tube etc. It is a kind of compensation components. By using the bellows affect extensional deformation, to absorb pipe, ducts and containers axial, lateral and angular displacement. It is also widely used for industry noise reducing and shock absorption.
Flange connection standard is in line with GB4216.3-4612.5 standard, as to other standards, also can be explained and acceptable. Levels of the product working pressure are 0.6Mpa 1.0Mpa 2.5Mpa.
