DN80 Union Type Threaded Rubber Expansion Joint Vulcanized
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.
Performance characteristics of threaded rubber expansion joint
1. The threaded rubber expansion joint has the advantages of small volume, light weight, good elasticity and convenient equipment maintenance;
2. The threaded rubber expansion joint can have lateral, axial and angular displacement, and is not limited by the non centering of the pipe and the non parallel of the flange.
3. With the increase of temperature, the threaded rubber expansion joint will expand and contract;
4. The threaded rubber expansion joint can reduce the noise transmitted by the structure and has a strong damping capacity;
5. According to different scenarios, the threaded rubber expansion joint with different rubber materials can more effectively prevent the corrosion of corrosive media on the inner wall of rubber joints, and improve the service life.

Note: 1. The special requirements of threaded rubber expansion joint can be customized according to the user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of threaded rubber expansion joint can be used as natural rubber, ethylene propylene diene monomer rubber, chloroprene rubber, butyl rubber, butadiene rubber, fluorine rubber, etc. When the threaded rubber expansion joint above DN200 is used for suspended water supply, the pipe must have fixed support or fixed support, otherwise the threaded rubber expansion joint shall be installed with anti falling device.

Threaded rubber expansion joint production Flow
Do you know how is a threaded rubber expansion joint made?Let's see with JINGNING.
It is very important to select the appropriate threaded rubber expansion joint of the pipeline, understand the compatibility of the medium with the selected material, the full temperature, pressure and vacuum range, the required movement and the size between the pipeline flanges. With this information, Jingning application engineers can help determine the ideal threaded rubber expansion joint for any application.
Threaded rubber expansion joint advantage
1. The threaded rubber expansion joint is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.
2. Threaded rubber expansion joint are connected with pumps, valves, fire-fighting equipment, pipes with large vibration and pipes with frequent changes of cold and heat.
3. The natural rubber content of threaded rubber expansion joint is 47%, which can be used continuously for 15 years without aging.
We introduce foreign advanced technology and combine with China's production experience. In the threaded rubber expansion joint manufacturing operation, the inner side bears high pressure, and the nylon cord and the inner side rubber are combined better, which can bear higher pressure than the ordinary threaded rubber expansion joint. Threaded rubber expansion joint is characterized by perfect combination of inner rubber layer, bright, clean and seamless; the label of threaded rubber expansion joint adopts vulcanization process, which perfectly matches the ball of threaded rubber expansion joint.
Threaded rubber expansion joint application
Threaded rubber expansion joint can be widely used in water supply and drainage, circulating water, HVAC, fire protection, paper making, pharmaceutical, petrochemical, ship piping system, water pump, compressor, fan and other piping systems. Ordinary threaded rubber expansion joint is used to transport - 15 ℃ - 115 ℃ air, compressed air, water, water, seawater, oil, acid and alkali. Special type threaded rubber expansion joint is used to transport medium, oil or strong alkali, strong acid and solid materials above - 30 ° C to 250 ° C.
