The Liangda Rubber Expansion Joint is 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/Wastewater Treatment.
The Liangda Eccentric flexible rubber bellow is a twin sphere design with more length, the supply range is from 40mm*25mm to 600mm*700mm, and design pressure can withstand 1.0MPa/1.6MPa/2.5MPa working pressure.
The rubber expansion bellows are engineered special for pipe reducing and offsetting pipe misalignment. 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 Liangda expansion joint rubber 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
10, 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
11, No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JIS

Note:
1. Pressure/Vacuum rating is based on neutral installed length(F/F).
2. Pressure rating is based on 30°C operating temperature. The pressure rating is reduced at higher temperatures
3. Weights in the above table are joints with DIN PN16 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 PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.
