1. Flange has been painted
Flange paint treatment to ensure that in the case of wet rust is not easy.
2. Improved tightness.
3. Reduce the damage caused by friction.
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%.
4. Good quality of flange
The rubber joint USES good quality flange, the service life increases 5 years above.
The rubber ball is made of EPDM rubber, containing more than 40% rubber, which has a longer service life than conventional rubber.
6. The number of lining conforms to the standard requirements
The number of rubber ball inner lining exceeds the standard requirement.
7. Increase of seismic coefficient
Rubber ball ball added steel wire, anti - twist, anti - seismic coefficient increased 10%.
8.Add steel ball
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.The ball is processed by a process
The spheroid is manufactured by one process, which ensures the smoothness and pressure of the spheroid.
