High Pressure Rubber Joint
High Pressure Rubber Joints, is also one type of single arch rubber joints, are integral rubber flanged 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.

Features and Benefit:
·Absorbs directional movement
·Absorbs vibration, noise and shock
·Compensates for more misalignment
·Wide flowing arch design
·Economical fully molded construction
·Integral rubber flange design, prevent rubber end pulling out
·Control units supplied for safety
·No gaskets required; integrally rubber flanged design

Notes:
1. Supply range can be up to DN300, 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 products will only be sold with control units.
4. Pressure rating is based on 30℃ operating temperature. The pressure rating is reduced at higher temperatures.
5. 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.
