Flanged Materials: Carbon Steel Q235 with Epoxy Coating
The flange is forged with JB / T 81-94 standard. No difference.
It has limit bolts to prevent the ball from pulling off.
It has a compression ring made of carbon steel. A steel cord is wound around the ball cord to increase the ball strength.
The rubber sphere is made of EPDM rubber. And the rubber content is more than 40%. It has the characteristics of tensile resistance, compression resistance, aging resistance, high temperature resistance and low temperature resistance.
Each product will be inspected for sphere appearance, hardness, air tightness, pressure resistance and flange pull-out prevention before leaving the factory. Unqualified products are strictly not allowed to leave the factory.
The flange is spray-treated. Spray thickness is greater than 250um, which can reduce the rust generated in humid environment by more than 70% and improve the anti-oxidation rate by more than 20%.
