Product Description

The HOLA rubber joint coupling are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces.
Because of rubber has superior capability in resistance of acid, alkali, oil, and electrolytic, Rubber Expansion Joint has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: Chemical/Petrochemical, Marine, Power Generation, Pulp/Paper, Steel Mills and Water/Waste water Treatment.

The series of Rubber Joints are including hose joint, expansion joint and so on.In a flexible rubber hose coupling double ball (can be scratched the dual ball soft rubber joints) used for metal pipe flexible connection between the function of hollow rubber products, and reducing joint belong to the same series products, soft take over by the inner and outer layer of glue, cord fabric layer and steel wire circle tubular rubber parts, flange or parallel again after vulcanization molding and metal joint loose tube.
The rubber joint is engineered special for pipe reducing. It offers an economic and space saving way to combine a reducing pipe fitting with an expansion joint, different sized pipe can be jointed by big and small flanges. Specifying Concentric Rubber Reducer to help solve piping system vibration or movements problems as well as connection problems.
Features and Benefits:
1, Versatile hand-built construction. Made in China
2, Absorbs directional movement
3, Absorbs vibration, noise and shock
4, Compensates for misalignment
5, More compensation capability
6, Combine a reducing pipe with an expansion joint
7, Embedded steel reinforce ring enable the pressure resistance
8, Solid galvanized steel floating flanges speed the installation time
9, Special grooved flange ring design, prevent rubber end pull out
*0, High tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings
*1, No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN*0/*6 drilling standard, other flange drilling available, including ANSI **0lb/**0 lb, BS, and JIS
Note:
1. Pressure/Vacuum rating is based on neutral installed length(F/F).
2. Pressure rating is based on *0℃ operating temperature. The pressure rating is reduced at higher temperatures
3. Weights in the above table are joints with DIN PN*6 drilling retaining ring flanges.
4. Movements shown in the above table are non-concurrent.
5. Control units must be used when piping is not properly anchored.
6. Rated pressure in the above table is the maximum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure is 4 times " work pressure".
7. Normally, the flange drilling is based on DIN PN*6, ANSI **0/**0/**0 lbs, BS PN*0, JIS *0K are also available upon request.
