Ductile Iron Flange Rubber Joint

Size Range:DN50-600

Pressure: PN10/16/150LB

Seat Material:EPDM

Flanged Material:Ductile Iron

Features: Flexible rubber joints, abbreviated as rubber joints, are composed of fabric-reinforced rubber parts and metal flanges. They are used as joints for isolating and reducing noise and displacement in pipelines.
It is a type of pipeline joint with high elasticity, high air tightness, resistance to media, and resistance to weather conditions. By absorbing and transmitting vibrations, it reduces the noise and vibration of pipelines and mechanical equipment, thereby improving the stability and service life of the equipment. In pipelines with large vibrations, rubber joints can effectively reduce the noise and vibration of the pipelines, ensuring the stability and safety of the pipelines.

Product advantages

1. The flange is made of ductile iron and has a spheroidization rate of grade 3.

2. The flange is sprayed with international renowned brand Akzo epoxy resin.

3. The spherical body is made of imported EPDM rubber and is vulcanized using our own factory process, ensuring controllable quality and long service life. It also has the British WRAS certification.

4. The thickness of both ends of the rubber ball is increased by 10mm and a steel wire ring is added inside, making the ball more resistant to detachment and twisting.

5. The number of cord fabric inside the ball exceeds the national standard, making it more resistant to pressure and tension.
