Stainless Steel Screwed Union Bspt Threaded Expansion Joint Rubber Thermal Expansion Joint
Rubber thermal expansion joint is a flexible connector made of rubber or rubber-like elastomeric materials, designed to accommodate thermal expansion, contraction, vibration, and misalignment in piping systems while maintaining a reliable seal. It effectively absorbs dimensional changes caused by temperature fluctuations, reduces stress on connected pipes and equipment, and prevents leakage or structural damage, making it widely used in industries such as HVAC, water treatment, chemical processing, and power generation.
Performance characteristics of Rubber Thermal Expansion Joint
1. Rubber connector for pipe has the advantages of small volume, light weight, good elasticity and convenient equipment maintenance;
2. Rubber connector for pipe 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 Bspt threaded expansion joint will expand and contract;
4. Rubber connector for pipe can reduce the noise transmitted by the structure and has a strong damping capacity;
5. According to different scenarios, Rubber connector for pipe 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.

Rubber Thermal Expansion Joint production Flow
Do you know how is a Rubber Thermal Expansion Joint made?Let's see with JINGNING.
It is very important to select the appropriate rubber connector for pipe 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.
Rubber Thermal Expansion Joint advantage
1. Rubber connector for pipe is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.
2. Rubber connector for pipe 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 Bspt threaded 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 Rubber connector for pipe 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 Rubber connector for pipe. Rubber connector for pipe is characterized by perfect combination of inner rubber layer, bright, clean and seamless; the label of Bspt threaded expansion joint adopts vulcanization process, which perfectly matches the ball of Bspt threaded expansion joint.
Rubber Thermal Expansion Joint application
Rubber connector for pipe 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 Rubber connector for pipe is used to transport - 15 ℃ - 115 ℃ air, compressed air, water, water, seawater, oil, acid and alkali. Special type Bspt threaded expansion joint is used to transport medium, oil or strong alkali, strong acid and solid materials above - 30 ° C to 250 ° C.
