Application field： Municipal construction, chemical industry, water treatment, electricity, petroleum, water supply and drainage, water conservancy projects.  

Product advantages:    

1.Flange and rubber ball wear less    

The radian of flange inner forged surface is 67 degrees, which reduces the damage caused by friction between flange and rubber ball by more than 95%.    

2.Flange is not easy to rust    

Flange after baking paint treatment, in the humid environment is not easy to rust.    

3.Increased tightness by 10%.    

4.Longer life    

Rubber joint flanges adopt standard flanges, the service life is increased more than 5 years.    

5.The content of EPDM is higher    

EPDM rubber balls, containing more than 40% of rubber, longer than conventional rubber life.    

6.High seismic coefficient    

Rubber ball added steel wire, anti - twist, anti - seismic coefficient increased 10%.    

7.Exceed national standards    

The number of rubber ball inner lining exceeds the standard requirement.    

8.Prevent the ball from pulling    

The thickness of both ends of the rubber ball increased by 10mm, and the steel ball was added to prevent the ball from pulling.    

9.Better sealing effect    

The rubber ball is connected with German waterline and the sealing effect is improved by 30%.
