Specifications
Henan Liwei Industry Co., Ltd:
1. Since 1988, Top 3 manufacturer of metal bellows in China;
2. The Main Drafting Committee of National Standard for Bellows;
3. Qualified Supplier for Nuclear Power Plant;
4. ISO9001:2008 and ISO14001:2004 Certified.
Metal bellows also called stainless steel bellows, stainless steel expansion joint, bellows expansion joint, etc., is the compensating element 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.
Bellows Expansion Joint is elastic vessel 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).
