Stainless Steel Screwed Union Bspt Threaded Joint NBR Threaded Expansion Joint
NBR threaded expansion joint is a type of flexible piping system component designed to accommodate axial, lateral, and angular movements in piping systems while providing a reliable seal. These expansion joints utilize stainless steel threaded unions with BSPT threads, combined with a general-purpose rubber bellows, to create a robust and versatile connection that can withstand a wide range of environmental and operational conditions.
Performance characteristics of NBR Threaded Expansion Joint
1. The NBR threaded expansion joint has the advantages of small volume, light weight, good elasticity and convenient equipment maintenance;
2. The NBR threaded 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 NBR threaded expansion joint will expand and contract;
4. The NBR threaded expansion joint can reduce the noise transmitted by the structure and has a strong damping capacity;
5. According to different scenarios, the NBR threaded 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.

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