Reducing rubber joints JGD-type (size head)
Author Admin Browse Posted 2011-07-25
 Name: JDX Reduced rubber joint type 
Features:
    Reducing the size of head, also called rubber joints, reducers shock absorber, Reducing soft rubber joints, rubber reducer fitting, pipe shock absorbers, shock absorber hose, flexible rubber connector. Rubber ball joints from the inside layer, enhanced multi-layer plastic scratch nylon cord fabric, rubber outer layer composite tubes. According to media of different rubber materials used are different, there are natural rubber, styrene butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber and so on. Reducing rubber joints, respectively, with heat, acid, alkali, corrosion resistance, abrasion resistance, oil and other functions.
Reducing the main characteristics of rubber joints of metal pipe connection solved the problem of different caliber, while the role of damping and noise reduction can save pipeline installation parts, and cost savings. It is from the inside layer, nylon cord enhanced rubber outer layer composite sphere composed of metal flange and set loose.
    Reducing rubber connector with high pressure, good elasticity, displacement volume, balance pipe deviation, absorb vibration and reduce noise effect, convenient installation, reducers rubber joints can be used in water supply and drainage, recycled water, HVAC , fire, paper, pharmaceutical, petrochemical, marine, pumps, compressors, fans and other piping systems. Common type used to transport -15 ℃ ~ 120 ℃ in air, compressed air, water, sea water, oil, acid and alkali. Special type used to transport -30 ℃ ~ 250 ℃ over the medium or oil, concentrated acid concentrated alkali, solid-state materials.
