Product Details

Expansion joint, also known as a compensator, is a type of compensation element. It can be divided into a flange expansion joint and pipe expansion joint according to the connection process. Flange connection expansion joint is composed of bellows (an elastic element), end tube, support, flange, trestle and other accessories.

The bellows absorb effectively the expansion and deformation of the pipeline size change, conduits and containers caused by thermal expansion and cold contraction, or compensates the axial, transverse and angular displacement of pipelines, also can be used for damping of vibration and noise transmissions. The stainless steel expansion joint can be used in heating pipes to prevent deformation or damage caused by thermal elongation or temperature stress during heating or to reduce forces on the pipe wall, valve or trestle structure.

The stainless steel expansion joint is mainly used to compensate axial displacement, lateral displacement or angular displacement (not recommended), is characterized by no thrust, corrosion resistance, high-temperature resistance, noise and vibration attenuation, especially suitable for hot air pipe and smoke pipe. World iron&steel supply and manufacture 304 stainless steel expansion joints in accordance with EN, ASTM, GB standards and we also made a variety of materials for wider application. The materials used in the pipe system are directly related to how to join the pipes and what types of pressure assembled in the pipe. For more information, call us today!
