Flanged Connector Pipe Expansion Joint EPDM Flexible Rubber Expansion Joint
Pipe expansion joint is used for hollow rubber products with flexible connection between metal pipes. Pipe expansion joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The pipe expansion joint takes advantage of the elasticity, high air tightness, medium resistance, weather resistance and radiation resistance of the rubber. The pipe expansion joint is made of polyester cord fabric with high strength and strong cold and hot stability, which is obliquely crossed and compounded, and then vulcanized by high pressure and high temperature mold. Pipe expansion joints are widely used in various pipeline systems.
Performance characteristics of pipe expansion joint
1. The pipe expansion joint has high internal density, can bear high pressure and good elastic deformation effect.
2. Pipe expansion joint can reduce vibration and noise, product design is light and convenient for installation and maintenance.
3. When the pipe expansion joint works, it can reduce the structure transmission noise and has strong vibration absorption ability

Note: 1. The special requirements of pipe expansion joint can be customized according to user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of pipe expansion joint can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the pipe expansion joint above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the pipe expansion joint shall be installed with anti falling device.
