Describe
KST-L threaded rubber joint
KST-L threaded rubber joint, also known as multi-ball thread flexible rubber joint, is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The threaded rubber soft joint utilizes rubber elasticity, high air tightness, medium resistance, weather resistance and radiation resistance. It is compounded with a high-strength, cold-hot and stable polyester cord fabric. It is vulcanized by high pressure and high temperature mold. The internal density is high, it can withstand high pressure, and the elastic deformation effect is good. Reduce vibration, reduce noise, good flexibility and easy to use.
 
[product alias]: flexible rubber joint, threaded rubber soft joint, shock absorber, shock absorber throat, threaded soft joint, threaded rubber flexible joint, threaded rubber pipe joint, etc.
[product pressure]: 1.0MPa-1.6MPa
[product specifications]: [DN15mm-DN80mm]
[Product Certification]: ISO9001-2008
[Scope of application]: [acid, alkali, corrosion, oil, hot water, cold water, compressed air, compressed natural gas, etc.]
[product material]: the sphere is natural rubber, the flange is carbon steel, stainless steel
 
Features
KST-L threaded rubber joint ball is composed of inner rubber layer, reinforcing layer with multi-layer scraping nylon cord fabric and rubber layer compounded with outer rubber layer. The rubber materials used are different depending on the medium, such as natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene rubber, silicone rubber, fluorine rubber, and the like. They have the functions of heat resistance, acid and alkali resistance, corrosion resistance, wear resistance and oil resistance.
 
Product use: The connection of threaded rubber joints with pumps and valves is especially suitable for pipes with large vibration and frequent changes in heat and cold.
 
Applicable medium: seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder.
 
Product application range: Because Gongyi Xinli KST-L threaded rubber joint has good comprehensive performance, it is mainly used for lifting and conveying raw water and sewage, water supply and cooling circulating water of thermal power plant, metallurgical industry, condensed water, chemical industry Pipeline transportation of chemicals, cooling in the petrochemical industry, dilution and flexible connections between long and short pipelines in other industries. Because rubber has high wear resistance, it is also suitable for the transportation of granular and powdery and vapor in all industries.
