KXT-B type silk buckle rubber flexible joint, also known as female threaded flexible rubber joint, female threaded rubber shock absorber throat, etc., is a kind of high elasticity, high airtightness, media resistance and weather resistance of pipeline joints. Silk buckle rubber flexible joint makes use of the material performance characteristics of rubber, using high strength, cold and heat stability of polyester cord fabric twill and its composite, after high-pressure, high-temperature mold vulcanization and become. The internal density is high, can withstand high pressure, elastic deformation effect is good. The soft joint has the characteristics of reducing vibration, noise, good expansion and contraction, easy to use and so on. Spherical structure and good sealing performance solves the problem of pipeline rupture and damage to pipeline connecting equipment due to thermal expansion and contraction, reduces medium impact, improves the service life of pipeline and protection of equipment. Widely used in cold water, hot water, compressed air and other media.
Product Features
It is characterized by high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect and easy installation.
Scope of Application
It can be widely used in water supply and drainage, circulating water, HVAC, fire fighting, papermaking, pharmaceuticals, petrochemicals, ships, pumps, compressors, fans and other piping systems, using units such as power plants, water plants, steel mills, water companies, engineering and construction.
