  • Jgd B2 Double Arch Rubber Joint Aluminum And S - China

    price: contact company for price

    The Liangda flexible expansion joint JGD-B2 are double arch designed

    with integral rubber flanges for tough, demanding industrial

    applications, as found in: Chemical/Petrochemical Plants, Industrial

    Process Piping Systems, Marine Services, Power Generation Plants,

    Pulp/Paper Plants, Steel Mills, Water/Wastewater and Pollution Control

    Systems. Installed next to mechanical equipment or between the anchor

    points of a piping system to: (1) Absorb Pipe Movement/Stress (2) Reduce

    System Noise (3) Isolate Mechanical Vibration (4) Compensate

    Alignment/Offset (5) Eliminate Electrolysis, (6) Protect Against Start-Up

    Surge Forces.

    The Liangda Double Arch joint rubber JGD-B2 is a twin sphere design with more length, the supply range is from 500mm to 1000mm, and design pressure can be 1.0MPa/1.6MPa/2.5MPa. Compared to Rubber Expansion Joint(JGD-1, JGD-2, JGD-3), mechanical and acoustical performance can be almost double by changing to the most commonly specified twin sphere construction. Twin sphere designs are more flexible and allow greater movement.

    Features and Benefits:

    1, Versatile hand-built construction. Made in China

    2, Bellows to Absorb directional movement

    3, Absorb vibration, noise and shock

    4, Bellows Compensates for misalignment

    5, More compensation capability

    6, Embedded steel reinforce ring enable the pressure resistance

    7, Solid galvanized steel floating flanges speed the installation time

    8, Integral rubber flange design, prevent pulling out

    9, 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

    10, No gaskets required; DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JIS


    1. rubber expansion JGD-B2 Supply range is from DN500 to DN1000.

    2. Control units must be used when piping is not properly anchored.

    3. The rated pressure 2.5MPa products will only be sold with control units.

    4. JGD-B2 Pressure rating is based on 30°C operating temperature. The pressure rating is reduced at higher temperatures.

    5. rubber joint expansion Weights in the above table are joints with DIN PN16 drilling retaining ring flanges.

    6. Movements shown in the above table are non-concurrent.

    7. 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'.

    8. Normally, the flange drilling is based on DIN PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.
