JIS stainless steel flange rubber joint pipe connection rubber expansion joint
Main feature of flexible rubber joint
1,Small volume, light weight, good flexibility, easy installation and maintenance.
2,When installation can produce transverse and axial, angular displacement, not affected by pipeline impassability heart, thread unparallel limit.
3, Work can reduce structure transfer noise, vibration absorbing ability.
4,We developed the company in seamless pressure rubber joint, in high temperature resistance, acid and alkali resistant, oil resistant pipe more effectively prevent the corrosive medium to rubber joint wall erosion and improve the service life.
Purpose: Pump valve connection fire fighting equipment, vibration large pipe cold and hot change frequent pipeline.
Advantages: High quality rubber joint recommend quotient lead to reduce vibration noise retractility, easy to use.
