An expansion joint is a device which is used to allow movement in a piping system while containing pressure.Feature1) Improve the flow circulation and avoid the bellow deformation . 2) Absorbs thermal expansion and shock 3) Structure: bellows + flat welding flanges 4) Main material, bellows : stainless steel 304; flanges: stainless steel 304 or carbon steel 5) Compensates converting misalignment 6) Compensates for exhaust converter misalignment 
 Application: 1. Heating and air conditioning installation 2. Hot water and fire protection system 3. Compressors inlet and outlet 4.Pipe with axial displacement by temperature or pressure changes 5.Thermal motors refrigeration circuit
