Working pressure and bursting pressure of flexible rubber expansion joints
- Flexible rubber expansion joints working pressure refers to a rubber expansion joints in the maximum working pressure, including pressure air, compressed air and water, water, water, oil, acids, alkalis and other fluids generated in the pipeline passes.
Flexible rubber expansion joints working pressure unit is MPa (Kgf / cm2).
Flexible rubber expansion joints working pressure of 0.6 MPa, 1.0MPa, 1.6MPa, 2.5MPa and the like. These four pressures are common. Of course, soft rubber joints working pressure include, but are not limited to these four four. The most commonly used American Standard operating pressure flexible rubber expansion joints are generally divided into class 150ibs, 300ibs, 400ibs like.
The bursting pressure of the flexible rubber expansion joint is the rubber expansion joint, which may be caused by blasting, tearing and damage under the pressure. Burst pressure requirement is higher than the work pressure, generally 1.8MPa, 3.0map, 4.8map, 5.5map, etc..
So how to choose the work pressure of the flexible rubber expansion joints?
This should be based on pump and pipeline pressure to choose, must correspond to the working pressure of the pipeline, so as not to cause damage to the flexible rubber expansion joints and pipeline valve.
