Product description

  EPDM Pipe Rubber Ring Joint   1. Our factory's introduction:  The Liangda Rubber Expansion Joints 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. Pipe joints   2. Properties of EPDM Pipe Rubber Ring Joint :
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.   3. The specification of EPDM Pipe Rubber Ring Joint  :
The Single Sphere Rubber Joint is a single sphere design with less length, the supply range is from 25mm to 3000mm, and design pressure can be 1.0MPa/1.6MPa/2.5MPa, which is always used where low cost or space limitation control.    4. Features and Benefitsof EPDM Pipe Rubber Ring Joint :   1, Versatile hand-built construction. Made in China
2, Absorbs directional movement
3, Absorbs vibration, noise and shock
4, Compensates for misalignment
5, Wide flowing arch design
6, Virtually eliminates sediment buildup
7, Economical fully molded construction
8, High vacuum rating (up to 30" Hg) can be supplied for certain sizes
9, Special grooved flange ring design, prevent rubber end pulling out
10, Solid galvanized steel floating flanges speed the installation time
11, 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
12, 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   4. Note about EPDM Pipe Rubber Ring Joint  :
1. Rubber expansion joints supply range can be up to DN3000, detailed data can be offered upon request.
2. Control units must be used when piping is not properly anchored.
3. The rated pressure 2.5MPa rubber expansion joints will only be sold with control units.
4. Rubber expansion joint pressure rating is based on 30°C operating temperature. The pressure rating is reduced at higher temperatures.
5. Rubber expansion joint 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". Rubber expansion joint test pressure is 1.5 times "working pressure", Burst pressure is 4 times " work pressure".
8. Normally, the rubber expansion joint flange drilling is based on DIN PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.   5. More styles of   EPDM Pipe Rubber Ring Joint :
