Metal Bellows Expansion Joint is designed to absorb thermal expansion, pipeline movement, vibration and mechanical stress in industrial piping systems. It uses stainless steel bellows as the flexible element and can compensate axial, lateral or angular movement according to different pipeline layouts and working conditions.

Compared with rubber expansion joints, metal bellows expansion joints are more suitable for high temperature, high pressure, steam, hot water, oil, gas and other demanding industrial applications. The stainless steel bellows provide good flexibility, pressure resistance and long service life under suitable working conditions.

This product is widely used in power plants, chemical plants, heating systems, steam pipelines, oil and gas pipelines, water treatment systems, HVAC systems and general industrial pipeline projects.

Hongze Valve can customize metal bellows expansion joints according to pipe size, pressure rating, movement requirement, working temperature, medium, bellows material, connection type and project drawings. Common bellows materials include SS304, SS316L, SS321 and other stainless steel grades. Flange, welding end and other connection types are available.
