Rubber joints, also known as flexible rubber joints, flexible rubber joints, soft rubber joints, shock absorber, (shock absorbers throat), rubber shock absorbers, rubber expansion joints and so on. The product consists of inner and outer layers of plastic, ply and bead composition tubular rubber parts, high temperature, high pressure molding after curing with metal flanges or parallel connector loose jacket combination. This product utilizes the high elasticity of rubber, high gas resistance, chemical resistance, weatherability and resistance to radiation and other advantages to reduce vibration and noise, and thermal expansion and contraction due to temperature changes from the compensation due to the widely used various piping systems.
Connection: Generally loose flange type (semi-hermetic), fixed flange (sealed), clamp and threaded connections.
Soft rubber joints Material:
Soft rubber joints ball is from the inside layer, scraping gum enhanced multi-layer nylon (nylon) cord fabric, rubber outer layer composite tubes. Depending on the medium used rubber material is also 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.
1) It owns internal higher density to bear higher pressure as well as ideal elastic deformation.
2) It designs high radian section ,long curve,which has large displacement fuction
3) It is extremely suitable for geologic,large extend of sedimentation places and places are easy to be damaged due to frequent alternation of heat and coldness.
4)The elastic slide transfer and deformation of rubber and the heat dispersion of mechanical force may well prevent the physical damages from displacement of pumpd,valves and pipes.
5)As s poor conductor,it is an ideal environmental product to reduce the vibration and noise in transmission.
6)The product is designed with smooth inner walls,after testing,it is proved to have no any influence on the flow speed and flux of the medium,and keeps stainless for ever,accordingly it will be free of maintenance in operation.
7)The material are good sealing, light weighting, easy to fix and maintain, also has longworking
