Our Corrugated Expansion Joint is a common pipe part for power plants, chemical plants, city gas lines, water supply, and HVAC. We have been doing this for over 20 years. This corrugated expansion joint is stable, durable, and a good value. Many customers trust it for a long time. We use 304 or 316L stainless steel for the bellows. The flanges and pipes use carbon steel or stainless steel. We use hydraulic and roll forming to make the bellows.

This thing takes in axial, lateral, angular, and combined moves. It works from -20℃ to 600℃. It handles pressures from PN6 to PN40. Each corrugated expansion joint gets a pressure test at 1.5 times the design pressure. We also do an air tightness test at 1.1 times. Its fatigue life goes over 8,000 cycles. It stands up to heat, pressure, and corrosion. It also cuts down vibration and noise. Our standard sizes are in stock and ship fast. We give a 24-month warranty
