Stainless Steel Metallic Bellows Expansion Joint
Multi-ply SS metallic bellows absorbing thermal expansion in piping systems. Available DN 15 to DN 12,000. Fatigue, yield, and rupture tested per EJMA/ASME standards. Choose this (prod_e1) over the standard axial joint (prod_e1b) when your application requires multi-ply high-cycle fatigue life, exotic alloy material (Incoloy, Inconel, Hastelloy, Titanium), very high pressure above 16 bar, or PED/AD2000 third-party certification documentation.
Application: High-pressure steam exhaust systems, chemical process pipes, heat exchanger connections, and piping requiring thermal movement compensation. Best choice for high-cycle fatigue duty, exotic materials, pressures above 16 bar, or where PED/AD2000 certification is required. For standard steam and water pipelines at moderate pressure, the axial expansion joint (prod_e1b) is more cost-effective.
