Name: JGD-WD-type high-pressure rubber joints DIN
Features:
DIN high-pressure rubber joints , also known as shock absorbers, pipe shock absorbers, shock absorbers throat, soft joints. German standard high-pressure rubber joints of the product is the flexible metal pipe couplings, from the inside layer, nylon cord enhanced rubber compound outer layer loose ball and set composed of metal flange.
German standard high-pressure rubber joints with a high pressure, good elasticity, displacement volume, balance pipe deviation, absorb vibration and reduce noise effect, easy installation and so on. Can be widely used in water supply and drainage, recycled water, HVAC, fire, paper, pharmaceutical, petrochemical, shipping, 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.
