Various pipe fittings soft flexible connection system for starting role between the metal pipe hollow rubber products, this product can reduce vibration and noise, and thermal expansion and contraction due to temperature changes from the compensation due to the pair, widely used systems. Suitable medium: water, fresh water, hot water, drinking water, sewage, oil, fuel oil, lubricating oil, refined oil, air, gas, steam and particulate powder. . Soft joints also called soft rubber tube joints, rubber joints, rubber flexible connector, can be curved around the joints, high pressure rubber joints, rubber shock absorbers. By way of loose flange connections, fixed flanges and threaded three kinds; according to the structure can be divided into single ball, double ball, bending the ball and so on. By the inner and outer layers of plastic, ply and bead tubular rubber by vulcanization molding and metal flange or parallel connector loose combination. This product can reduce vibration and noise, and thermal expansion and contraction due to temperature changes from the compensation due to the pair, widely used in various piping systems. Shanghai Songjiang flexible connector is a high flexibility, high air tightness, chemical resistance and weather resistance of the pipe joints. The product utilizes rubber elasticity, high air tightness, chemical resistance, weather resistance and radiation resistance, etc., made of high strength, strong cold bias stability of polyester tire cord fabric with composite later, after pressure, high temperature vulcanization molds. As the soft rubber joints has a good overall performance, so it is widely used in chemical, construction, water supply, drainage, oil, light and heavy industrial, refrigeration, sanitation, plumbing, fire, electricity and other infrastructure projects. Two features: internal high density, can withstand high pressure, good elastic deformation effects. Advantages: shock absorption, noise reduction, lightweight, non-toxic. Three purposes: pump, valve connections, larger pipe vibration, frequent changes of hot and cold pipes. Four Suitable medium: water, fresh water, hot water, drinking water, sewage, oil, fuel oil, lubricating oil, refined oil, air, gas, steam and particulate powder.
