DN1200 single ball expansion rubber joints introduction
Rubber joint is also called: flexible rubber expansion coupling, rubber soft connection, and soft rubber joint, rubber compensator, rubber shock hose, rubber shock reducer, is one kind of high elasticity, high air tightness, medium resistance and weather ability pipe fittings.
Rubber expansion joint consists of outer rubber, inner rubber, framework layer, and reinforcing bar and flange. Relying on rubber’s special performances as long range elasticity, air impermeability, medium, climate and radiation resistance, rubber expansion couplings can reduce the vibration and noise of pipeline, and can be caused by the temperature change of heat bilges cold shrink compensation effect.
According to different material, acid resistance rubber joint, alkali proof rubber couplings, oil resistance rubber couplings, thermos table rubber couplings, low temperature resistance rubber joint, wear resistance rubber coupling can be made to suitable for various kinds of medium and environment.
Directions of use:
When expansion rubber joint was used in high water, pipe must have fixed support or fixed bracket, or the product should be installation device to prevent pulled off. The fore of fixed support or fixed bracket must be greater than the axial force.
