What It Does: Made for Big Size Pipe Movement
Our Flexible Pipe Flange is made for big size pipe movement compensation. We use it in city water supply, heat networks, chemical circulation, and waste water treatment. We have been making pipe parts for over 20 years. This flexible pipe flange has strong sealing, handles pressure well, and lasts a long time. It keeps big size pipes safe. We use 304 or 316L stainless steel for the bellows. It has good spring back and fatigue resistance. The flanges are forged carbon steel or stainless steel. They meet international standards.


Real Data You Can See
This thing works from -50℃ to 350℃. It handles pressures from PN6 to PN25. Each flexible pipe flange gets a water test at 1.5 times the design pressure. We also do an air tightness test at 1.1 times. It takes in movement from heat expansion, settling, and vibration. It stops pipes from breaking, flanges from loosening, and equipment from damage. The flange connection does not need welding. Installation is fast. The stainless steel body resists waste water, acids, alkalis, and aging. It lasts over 15 years. The seal is stable with no leaks and no upkeep. We support custom sizes from DN50 to DN1200. Our factory is 10,000 square meters with 50 workers. We check every unit before shipping. We give a 24-month warranty.
