Product Description

Flanged metal expansion joint is a flexible component designed to effectively compensate for axial deformation. It is composed of metal corrugated pipes and components, with the characteristics of flexibility, thin walls, and transverse ripples, which endow it with the ability to expand and contract. The working principle of the bellows expansion joint mainly relies on its own elastic deformation ability, which can compensate for the axial, angular, lateral, and combined displacements of the pipeline caused by thermal deformation, mechanical deformation, and various mechanical vibrations.

NO	Name	Material
1	Flange	SS304,ss316,carbon steel,etc
2	Shipping Rod	SS304,ss316,carbon steel,etc
3	Bellow	Stainless steel
