Non Metallic Expansion Joint Bspt Threaded Joint Twin Sphere Expansion Joints Manufacturers
Non Metallic Expansion Joint is a flexible, corrosion-resistant component designed to accommodate thermal expansion, vibration, and misalignment in piping systems without relying on metal materials. Typically constructed from reinforced elastomers, fabrics, or composite materials, it provides reliable sealing and stress relief in applications where metal joints may fail due to chemical corrosion, abrasion, or extreme temperatures. Commonly used in industries such as chemical processing, wastewater treatment, and power generation, these joints ensure system longevity by absorbing dimensional changes, reducing noise, and preventing leaks in aggressive environments.
Performance characteristics of Non Metallic Expansion Joint
1. Non Metallic Expansion Joint has the advantages of small volume, light weight, good elasticity and convenient equipment maintenance;
2. Non Metallic 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 Bspt threaded expansion joint will expand and contract;
4. Non Metallic Expansion Joint can reduce the noise transmitted by the structure and has a strong damping capacity;
5. According to different scenarios, the Twin Sphere Union Rubber Joints 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.

Non Metallic Expansion Joint production Flow
Do you know how is a Non Metallic 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.
Non Metallic Expansion Joint Advantage
1. Non Metallic Expansion Joint is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.
2. Non Metallic 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 Twin Sphere Union Rubber Joints 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 Bspt threaded 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 Expansion Joints Manufacturers. Expansion Joints Manufacturers is characterized by perfect combination of inner rubber layer, bright, clean and seamless; the label of Twin Sphere Union Rubber Joints adopts vulcanization process, which perfectly matches the ball of Bspt threaded expansion joint.
Non Metallic Expansion Joint Application
Non Metallic 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 Expansion Joints Manufacturers is used to transport - 15 ℃ - 115 ℃ air, compressed air, water, water, seawater, oil, acid and alkali. Special type Expansion Joints Manufacturers is used to transport medium, oil or strong alkali, strong acid and solid materials above - 30 ° C to 250 ° C.
