Structure and Feature
"Double sphere expansion rubber joint:
Constructed of neoprene and nylon (other materials are available see charts below), the spherical shape allows pressure to exert itself uniformly in all directions, thus reducing the force exerted on pipe lines and equipmen t. Bias-ply tire cord provides strength, a high safety factor, and low force to move. Precision molding provides a dense, uniform carcass.
Double sphere expansion rubber joint material:
Double sphere expansion rubber joint ball is from the inside layer, enhanced multi-layer plastic scraper nylon cord, rubber outer layer composite tubes. Depending on the medium used rubber material is different, there are natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on. Respectively, with heat, acid, alkali, corrosion resistance, abrasion resistance, oil and other functions.
Connection:
Generally have threaded connection, flange, clamp connection and so on.
