JGD-B-type Reducing rubber joint is also called dampers, pipe shock
absorbers, shock absorbers throat, soft joints and so on.
This product is the introduction of foreign advanced production
technology, production process under high pressure in the inner,
nylon cord, and layer combination of better than the ordinary type
flexible rubber joint working pressure higher and better quality.
It is characterized by mixed layer within a natural one, smooth
seamless marks, labels, using vulcanization process, and products
together.The product is a flexible metal pipe couplings, from the
inside layer, nylon cord fabric enhanced composite outer layer of
rubber ball and the loose sleeve of metal flange formed. With a
high pressure, good elasticity equilibrium displacement of a large
quantity of pipe deviation, absorb vibration, reduce noise effect
is good, easy installation etc., can be widely used in water
drainage, recycled water, HVAC, fire, paper, pharmaceutical,
petrochemical industry, shipbuilding, water pumps, compressors,
fans and other piping systems. Common type used for transmission of
-15°C ~ 115°C in air, compressed air, water, sea water, oil, acid,
alkali and so on. Special type used for transmission of -30°C ~ 250
°C and above the above-mentioned medium or oil, concentrated acid,
alkali concentration, solid material.
1. It is strictly prohibited to install beyond displacement
2. Installing the bolt should be symmetrical and gradually
tightening in case of partial leakage.
3. When the working pressure is above1.6Mpa, the elasticity
pressure pad should be used over there to prevent bolts from
loosening during work.
4, during vertical installation, there should be vertical pressure
support in two sides of pipeline in case of pulling off when it
5. The installation position should stay away from heat sources,
ozone areas. Radiation, exposure and mediums out of product
requirement are strictly prohibited.
6. During transportation, loading and unloading, keeping it away
from sharp metal instruments in case of scarify the surface.
1. Small volume, light, flexible, easy to install and maintain.
2. It is capable of horizontal, axial and angular displacement
without the restriction of pipeline obstruction and flange
3. It reduces structural noise transmission with strong shock
absorption in service.
4. The inner seamless high-pressure rubber joint independently
developed by us prevents the inner wall of the rubber joint from
etching by the corrosive medium in high temperature, acid and
alkali and oil resistant pipeline, thereby extending its service
