How much pressure rubber joint can bear in the pipe?

Rubber joint work pressure refers to the rubber joint highest stress at work.It includes air, compressed air, water, sea water, hot water, oil, acid and alkali, such as fluid in the pipeline after, and the pressure.How to choose a rubber joint work pressure？  The work pressure of rubber joint  is  usually 1.0 MPa, 1.6 MPa. The two pressure use most.Of course, a single sphere of rubber joint including but not limited to these two kinds of work pressure, because it has 0.25 MPa, 0.6 MPa, 1.0 MPa, 1.6 MPa, 2.5 MPa. The single sphere rubber joint work blasting if too big, can cause in the use of blasting, the phenomenon such as tear.So when choosing pipe pressure don't exceed the burst pressure depending on pump and pipeline pressure to choose, be sure to corresponding to the working pressure of pipeline and equipment can not use small pressure rubber joint in pressure pipeline installation, in this way, will cause the rubber joint and pipeline equipment damage.First, will have a clear identity, in the packaging has pressure in the body of the rubber joint, moreover, we can see the thickness of the flange, if the flange is thinner, the rubber joint work pressure will be smaller, on the other hand, the pressure is bigger.
