CHINA DN80 Double Sphere Threaded Rubber Expansion Joint

Threaded rubber expansion joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The screw expansion joint is made of rubber double ball and metal plate movable joint by vulcanization of inner layer, reinforcing layer and outer layer. Threaded rubber expansion joint material: Forging / Casting (round or square), surface treatment galvanized; Threaded rubber expansion joint ball material: the inner layer is heat-resistant rubber, the outer layer is aging resistant rubber, the middle is reinforced cotton cord cloth.

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 details show

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 not only compensate axial, lateral and angular displacement, reduce noise, absorb vibration, but also threaded rubber expansion joint has anti-corrosion performance. Threaded rubber expansion joint also has excellent high pressure resistance, good elasticity and large displacement compensation. Moreover, the threaded rubber expansion joint has good vibration and noise reduction performance and is easy to install. Therefore, threaded rubber expansion joint is widely used in water supply and drainage, HVAC, fire protection, compressor, papermaking, pharmaceutical, ship, water pump, fan and other pipeline systems.
