What is single sphere expansion joint price?
Single sphere expansion joint is also called single arch expansion joint, single bellow expansion joint. It solves the problem of pipeline burst and damage to pipeline connection equipment caused by thermal expansion and contraction with its unique design, novel structure and good sealing performance, effectively improving the life cycle of pipelines and the protection of equipment.
And then it has so many advantages, so what is the single sphere rubber expansion joint price?
Depending on the type and material of the expansion joints, the price is different. Let’s take an example, such as a flanged expansion joint: size is 50mm, length is 105mm, material is EPDM & CS, its price is about $12. Let’s take another examplesize is 150mm, length is 180mm, material is EPDM & CS, its price is about $45.

Main uses and application scope of single sphere expansion joint
Widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire-fighting, electric power and other basic projects, especially for pipes with large vibration and frequent hot and cold changes.
Working principle and structural characteristics
This product mainly makes use of the good high elasticity, good sealing and thermal expansion and contraction of rubber to reduce the vibration and noise of the pipeline and play a certain compensating role for the thermal expansion and contraction caused by temperature changes.
Different rubber materials of single sphere expansion joint play different roles:
- Natural rubber NR (over water, below 80 degrees)
- Ethylene-propylene EPDM (high temperature below 150 degrees, acid and alkali resistance, corrosion resistance, power plant desulfurization, lime slurry, gas, etc.)
- nitrile rubber NBR (oil-resistant, including hydraulic oil, aviation kerosene and other oils, high-temperature resistance of 150 degrees or less)
- wear-resistant rubber TZ (wear-resistant, generally used in the mineral industry, granular media transport pipeline)
- special rubber (emulsion, sulfuric acid and other special media)
- lined with tetrafluoroethylene (lined with PTFE material, can be resistant to strong acids, strong alkalis, emulsions, dilute sulfuric acid, wear-resistant, high temperature 200 degrees, low temperature 100 degrees and other special industrial and mining environments)
