Stainless steel flange connection metal bellows compensator with armoured rings
Stainless steel flange connection metal bellows compensator with armoured rings
Expansion bellows can be designed with reinforcing or equalizing rings which are located around the outside of the convolutions, preventing bellows being forced out from high pressure. The principal purpose of these devices is to reinforce the bellows under internal high pressure, so that bellows does not squirm and equalize movement among all the convolutions.
Equalizing and reinforcing rings are made of carbon steel, stainless steel or other suitable alloys.
Reinforcing rings are usually Tee shaped in cross section and equalizing rings are normally fabricated from tubing or solid round bars of suitable material.
Bellows with reinforcing or equalizing rings can be made for any type of expansion joint (axial, lateral or angular etc.). The disadvantage of these bellows is the increased stiffness and limited movement of the bellows.
Flange connection general stainless steel metal bellow expansion joint is the most common and popular, it is mainly used in pipe connection, aborb the extension and compression of pipe, according to different working situation, usually we recommend different structure, but for most common, we recommend general stainless steel metal bellow expansion joint, it is consist of two flanges, tie rods and bellows, according to actual working situation, you can choose to add inner sleeve or change structure, and we can offer you drawing for confirmation, about the material of bellow, we can do SS304, SS316, SS321 and SS310s etc, for working pressure, we can do PN10,PN16, PN25, PN32, PN40 etc. And we can do OEM and ODM production for you.
