Rubber expansion joints

Bellow material available in neoprene, EPDM, Butyl, Nitrile, Hypalon, Viton or otherwise specified. Different material and design are suitable for different medium and different temperature range.

Production process of Rubber Expansion Joints: this product use the high air tightness of rubber elastic medium resistance of weathering and radiation resistance, high strength and a little cold and heat stability of polyester cord skew and the composite by high pressure, high temperature mold vulcanization and become.

Performance characteristics of Rubber Expansion Joints: 1 can be bent bending double ball rubber joint small volume light weight elastic good easy installation and maintenance and can be bent bending double ball rubber joint installation can produce horizontal axial angular displacement, not affected by pipe impassability heart, flange unparallel limit 3 can be bent bending double ball rubber joint work can reduce structure transfer noise, vibration absorbing ability and my company independent research and development in seamless high pressure rubber joint, in high-temperature resistance to acid and alkali resistant to oil pipeline more effectively prevent the corrosive medium for rubber joint wall erosion and improve the service life

Application medium of Rubber Expansion Joints:Air,compressed air,water,sea water,hot water,oil,acid,alkali,etc.

Purpose of Rubber Expansion Joints: and pump valve connection fire fighting equipment, vibration large pipe cold and hot change frequent pipeline

Advantages of Rubber Expansion Joints: high quality rubber joint recommend quotient lead to reduce vibration noise retractility, easy to use

Installation instructions of Rubber Expansion Joints: rubber joint pipeline construction, must let it in a state of nature, not the human when installing the product produce human deformation when pipeline medium for acid and alkali resistant oil temperature and other special material should choose higher than pipe work pressure a gear of the joint
