Threaded Union Molded Rubber Expansion Joints EPDM NBR BSPT
Standard
EPDM Thread-Connection expansion joint for high vibration absorbing
ability after surface and treatment and inspection of finished products.
Screw thread rubber joint is the soft joint of metal pipes, and
consists of inner rubber, nylon cord fabric, outer rubber compound
rubber ball and metal lap joint flanges. The product can endure
high pressure, maintain good elasticity, have large displacement to
balance pipe deviation, absorb vibration and make less noise and
have easy installation, etc.
Screw thread rubber joint can be widely used in the pipe system of
water supply, drainage, circulating water, HVAC, fire protection,
paper making, pharmacy, petroleum chemical industry, ship piping
system, water pump, compressor and fan etc. The normal type is used
to transport air ranges from - 15 °C to 115 °C, compressed air,
water, sea water, oil, acid and alkali etc. The special type is
used to transport the media above ranges from - 30 °C to 250 °C
above, oil or strong alkali, strong acid and solid material.
Screw thread rubber Flexible Expansion Joint , also known as
flexible joint, rubber expansion joint, rubber flexible joint, pipe
expansion joint, soft rubber joint etc.
We introduce advanced technology from abroad, and combine it with
Chinese production experience. In the manufacturing operation, the
inner side endures high pressure; nylon cord fabrics and the inner
rubber are better combined and can work under higher pressure than
normal flexible rubber joint. Its characteristics are that the
inner adhesive layer united perfectly, bright, clean and seamless;
the tag adopts the vulcanization process, perfectly matches the
product.
Threaded union rubber expansion joint Advantage:
A: 15 minutes zinc plating, high pressure resistance, high
temperature resistance, oil resistance, wear resistance, corrosion
resistance, acid and alkali resistance.
B: Connect with pump, valve, fire fighting equipment, pipe which
vibrate big, pipe which hot and cold change frequently.
C: Natural rubber content of forty-seven percent, can continue to
use for 15 years without aging.
EPDM Thread-Connection expansion joint for high vibration absorbing
ability can be customized DN15-DN80.
Rubber expansion joints are generally composed of smooth wave shape
compensation element with rubber flange at both ends and metal
flange. A loose sleeve structure is often used for metal flange.
The surface of the wave shape compensating element is rubber, and
the inner layer is made from multilayer of strong fiber or steel
band (wire). The layers of fiber or steel band (wire) has been
extended to the ends of the rubber flange, the flange has a hard
steel wire skeleton. The rubber expansion joint has a larger
displacement compensation ability, which can compensate the axial,
lateral and angular displacement, which can reduce the noise,
absorb the vibration and has anti corrosion ability. Rubber
expansion joints have excellent high pressure resistance, good
elasticity, large displacement compensation, nice vibration
absorption and noise reduction capability, convenient installation,
widely used in water supply and drainage, HVAC, fire control,
compressor, paper, pharmaceutical, ship, water pump, fan and other
piping systems.
