Buckle grooved flexible rubber joint generally is composed of inner layer 、fabric reinforced protection layer(layer increase with multilayer fractioning polyamide cord fabric)、middle layer、outer layer and end reinforced metal ring or steel wire circle, through high temperature and high pressure vulcanization molding, with metal flange or a combination of parallel loose tube compounding rubber hose. This product taking advantage of the high elasticity, medium resistance and weather resistance and radiation resistance of rubber can reduce the vibration and noise of pipeline, and can meet the compensation caused by changes in temperature effect on heat bilges cold shrink.
