OEM Double Sphere Rubber Joint DIN, ANSI

Hola Double Arch Rubber Expansion Joints are custom made to protect your piping systems form stress caused by vibration and thermal expansion and contraction, available in a variety of material and configurations.Our expertise, in designing and constructing rubber expansion joints, is reflected in their long service life and high operational reliability. Refer to the Product Data Sheets for more information.

Double ball rubber 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.

Twin sphere rubber expansion jointis 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.

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 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

NOTESNon-standard items beyond above tables available, such as other tubes materials, flange material, flange standard or F/F length, plz contact HOLA for more information.
