Rubber soft connection is used for anti-seismic and noise reduction of chemical pipeline system
Rubber soft connection is also called rubber soft joint, flexible rubber joint, flexible rubber joint, rubber shock absorber and so on.The products are mainly composed of internal and external rubber layer, curtain layer and steel wire ring, tubular rubber parts, after high temperature and high pressure vulcanization molding and then combined with metal flange loose sleeve.It is widely used in fire protection, chemical industry, pump valve and other pipeline systems, and plays the role of seismic noise reduction to absorb the displacement generated in the pipeline operation.

Use range | Due to its good comprehensive performance, flexible rubber connections are especially suitable for pumps, valves, pipelines with large vibrations, and pipelines with frequent changes in cold and heat. They are often used in seawater, fresh water, cold and hot water, drinking water, and domestic sewage. , Crude oil, fuel oil, lubricating oil, refined oil, air, natural gas, steam and dust fields. |
External form | Single-ball rubber joints, double-ball rubber joints, three-ball rubber joints, concentric reducing rubber joints, eccentric reducing rubber joints, clamping rubber joints, 90° rubber elbows, etc. |
Features | 1. The internal density is high, can withstand high pressure, and the effect of elastic deformation is good. 2. Vibration reduction, noise reduction, lightweight product design, convenient installation and maintenance. 3. It can reduce the transmission noise of the structure while working, and has a strong vibration absorption capacity. |
installation steps | 1. The flanges should be welded vertically before installation (note: the flange waterline faces outwards, and the installation distance for the rubber soft connection is reserved between the flanges). 2. Use fasteners to connect the flanges at both ends of the rubber soft connection to the pipe end flanges. (Note: Use the diagonal method to tighten the nuts in parallel, and do not bias them.) 3. After installation, perform a hydraulic test on the rubber soft connection. After the water is tested and weighed, the connection bolts are tightened again in step 2 to prevent local leakage. |
