Product Description

Product Description

Introduction:

A metal bellows expansion joint consists of a bellows (flexible element) as its core working component, along with accessories such as end pipes, brackets, flanges, and conduits. It functions as a compensation element, utilizing the elastic deformation of the bellows to absorb dimensional changes in pipelines, ducts, or vessels caused by thermal expansion/contraction, as well as to compensate for axial, lateral, and angular displacement. Additionally, it serves to reduce noise and vibration.Widely used in modern industries, these expansion joints are essential for maintaining pipeline integrity and operational safety in various applications.

Structural features:

1. Core Component: Flexible metal bellows (elastic element)
2.Accessories: End pipes, flanges, brackets, conduits
3.Primary Function: Absorbs thermal expansion/contraction and mechanical displacement
4.Secondary Benefits: Noise & vibration damping
5.Industrial Applications: Petrochemical, power plants, HVAC, and more
