Basic Info

Model No.: JIS JOINT

Product Description

JIS rubber soft joint is also known as ANSI flexible rubber soft joint, shock absorber, Expansion Joint, pipeline shock absorber, shock absorber throat, soft joint, it mainly uses the good high elasticity of rubber, good sealing performance and thermal expansion and cooling It can reduce the vibration and noise of the pipeline, and play a certain role in compensating for thermal expansion and contraction caused by temperature changes.
JIS rubber soft joints are divided into two types: concentric concentric radial foot soft joints and concentric reducing rubber soft joints. Among them, concentric reducing rubber soft joints adopt advanced production technology, and the inner layer is subjected to high pressure during the production process. It is better combined with the rubber layer, and has higher working pressure and better quality than ordinary flexible rubber joints. It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance.
The composition of the JIS flexible rubber soft joint is: the inner layer is colloidal, the middle layer is reinforced with SNT series nylon 66 ultra-high-strength industrial silk cord fabric, and the outer rubber layer is compounded. of metal flanges.
Main parameters of JIS rubber soft joint
Working pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa
Working temperature: -40 degrees to 80 degrees (also can process high temperature resistant rubber soft joints)
Nominal diameter: DN32-DN1000
Material of main parts
Ball body: NR, CR, IIR, NBR, FKM, EPDM
Inner and outer lining: NR, CR, IIR, NBR, FKM, EPDM, PTFE
Main frame: Nylon cord
Flanges for rubber joints: cast steel, forged carbon steel (Q235), stainless steel (201, 304, 316, 321), plastic (PVC, PPC)
JIS rubber joints are widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power and other basic projects, especially suitable for pipelines with large vibration and frequent changes in cold and heat.
ANSI single sphere rubber soft joint, the rubber material used is different, can play different roles:
1. Natural rubber NR (over water, below 80 degrees)
2. EPDM (high temperature below 150 degrees, acid and alkali resistance, corrosion resistance, power plant desulfurization, lime slurry, gas, etc.)
3. Nitrile butadiene rubber NBR (oil resistance, including hydraulic oil, aviation kerosene and other oils, high temperature resistance below 150 degrees)
4. Wear-resistant rubber TZ (wear-resistant, generally used in the mining industry, granular media pipelines)
5. Special rubber (emulsion, sulfuric acid and other special media)
6, lined with tetrafluoroethylene (lined with polytetrafluoroethylene material, which can resist strong acid, strong alkali, emulsion, dilute sulfuric acid, wear resistance, high temperature resistance of 200 degrees, low temperature resistance of 100 degrees and other special industrial and mining environments)
JIS double sphere rubber soft joint solves pipeline bursting and damage to pipeline connection equipment caused by thermal expansion and cold contraction with unique design, novel structure and good sealing performance, effectively improving the service life of pipeline and the protection of equipment. Compared with the single sphere, the double sphere has a larger compensation amount. It is widely used in various pipeline systems. Connections with pumps and valves, fire-fighting equipment, pipelines with large vibrations, and pipelines with frequent changes in cold and heat. Mainly used for lifting and conveying raw water and sewage, feed water and cooling circulating water in thermal power plants, metallurgical industry, condensate water, pipeline transportation of chemical substances in chemical industry, cooling, dilution in petrochemical industry and other industries. Flexible connection. Because rubber has high wear resistance, it is also suitable for low-temperature transportation of granular and powdery and vapor in all industries.
