● Screw rubber flexible joint is also called threaded rubber expansion joint, shock absorber, shock absorber throat, screw soft joint, screw rubber pipe joint, etc. Threaded rubber expansion joint is composed of elastic rubber joint, plane movable joint, loose metal flange or threaded pipe flange, which is used for vibration isolation, noise reduction and displacement compensation.

● threaded rubber expansion joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The flexible rubber expansion joint is composed of inner rubber, polyester cord reinforcing layer, outer rubber and composite rubber tube. The flexible rubber expansion joint of threaded rubber expansion joint can choose any kind of inner and outer rubber materials, such as IIR, Cr, EPDM, NR, NBR, etc. the outer and inner layers of rubber materials can be different.

● However, the frame layer of the threaded rubber expansion joint is made of polyester fabric, and the reinforcing layer has steel rings. It can be made into acid, alkali, corrosion, oil, heat and other varieties according to different materials, and can adapt to a variety of media and environment. There are many kinds of threaded rubber expansion joint flange materials, including Q235, SS304 and SS316.

The threaded rubber joint is composed of inner and outer rubber layers, cord layers and wire rings, which are formed by vulcanization and then combined with metal flanges or parallel joints. It is a flexible part used at the pipeline connection. Because of its superior performance and advanced production technology, it is widely used in construction, water supply and drainage, fire protection, water heating, chemical engineering, electric power and other fields. The main raw material of the product body is rubber, which takes advantage of its high elasticity, high air tightness, weather resistance and radiation resistance to absorb the lateral, axial and angular displacement caused by pipeline vibration; Therefore, the vibration and noise of the pipeline can be reduced, and the thermal expansion and contraction caused by temperature change can be compensated;

Screw thread rubber joint has good comprehensive performance and is mainly used for flexible connection between long and short distance pipelines in industries such as improvement and transmission of raw water and sewage, water supply and cooling circulating water, metallurgy, condensate, chemical pipeline transportation, petrochemical cooling, dilution, etc. Due to its high wear resistance, rubber is also suitable for particle, powder and steam transportation in various industries.
