DN20 Stainless Steel Screwed Union Bspt Expansion Joint Manufacturers
Expansion joint manufacturers are companies that design and produce flexible connectors used in piping and ducting systems to absorb movement, vibration, and thermal expansion. These manufacturers typically offer a range of products such as rubber, metal, and fabric expansion joints, tailored for various industries including HVAC, water treatment, power generation, petrochemical, and construction. Their main goal is to ensure system safety, reduce stress on equipment, and enhance the durability and performance of pipelines and machinery.
Performance characteristics of Expansion Joint Manufacturers
1. The expansion joint manufacturers has the advantages of small volume, light weight, good elasticity and convenient equipment maintenance;
2. The expansion joint manufacturers 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 expansion joint manufacturers can reduce the noise transmitted by the structure and has a strong damping capacity;
5. According to different scenarios, the expansion joint manufacturers 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.

Expansion Joint Manufacturers production Flow
Do you know how is a Expansion Joint Manufacturers made?Let's see with JINGNING.
![]()
It is very important to select the appropriate expansion joint manufacturers 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.
Expansion Joint Manufacturers advantage
1. The expansion joint manufacturers is galvanized for 15 minutes, resistant to high pressure, high temperature, oil, wear, corrosion, acid and alkali.
2. Expansion joint manufacturers 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 expansion joint manufacturers 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.
Expansion Joint Manufacturers application
Expansion joint manufacturers 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.
