Product description:
1.Expansion joint is also called bellows or compensators, which are designed for axial, lateral and angular movements, misalignment and/or vibration in piping systems.
2.Expansion joints come with three convolutions as a standard. More than three convolutions can be customized and the more convolutions, the more movement an expansion joint will provide. Various reinforcements of rings and outer shells are available for high pressures, temperatures or vacuum performance. Tie rods and hinges are designed to limit maximum and minimum movements or preventing movement altogether in certain planes.
3.If there is no specific requirement for flange, it will be as per ANSI B16.5 and HG/T 20592 PN1.0MPa standard.
4.Lining material: PTFE, PFA etc.
5.Nominal diameter: DN25~DN3000
When the size of expansion joint is bigger than DN300, the type with stainless steel housing for vacuum resistant is recommend.
We have more than 10,000 sets on stock,which can provide for project and delivery in short time.
