stainless steel bellows DN40 SS304

Description

 
Metal Bellows (they are also called compensators) are compensating elements for thermal expansion and relative movement in pipelines, containers and machines. They consist of one or more metal bellows, connectors at both ends, and tie rods that depend on the application. They are differentiated according to the three basic types of movement: axial, angular and lateral expansion joints. 
Metal Bellows are elastic vessels that can be compressed when pressure is applied to the outside of the vessel, or extended under vacuum. When the pressure or vacuum is released, the bellows will return to its original shape (provided the material has not been stressed past its yield strength). 
 
1.Reasonable structure, good elasticity, large range of compensation pipeline and little counterforce to the brackets of pipeline. 
2.Shock absorption and noise decrease, heat and dust insulation, environmental protection and simple structure bracket. 
3.The displacement can be deflected to prevent damagment caused by subsidence of connected brackets and equipment base. It can adapt itself to the centrifugal difference of pipeline installation to provide convenience to installation and maintenance. 
4.Good resistance to milling, heat, aging and corrosiveness and long service life. 
5.Little resistance and little weight. Each performance is better than the compensation device of other materials. 
6.The temperature range of media is wide:*****0°c
