Diameter 127mm steel pipe, and diameter 127mm rubber hose how to connect?

Diameter 127mm steel pipe, and diameter 127mm rubber hose how to connect?

Answer:

According to GB1187, the rubber tube with an inner diameter of 127 has the maximum working pressure of 0.7MPa. The internal diameter tolerance is 2, and the outer diameter of the steel pipe is 127. If the purchase is appropriate, it should be sheathed, but the pipe factory is always taking negative tolerances.
Connection method:1, send special purchasing rubber pipes, as far as possible to choose the correct tolerance.2, if the work pressure is not more than 0.7MPa, the end of the steel pipe can be in accordance with the rubber tube inside the car, a knife.3, the processing of a casing.
A metal ring is sheathed inside the rubber tube, and the rubber tube with the metal ring is sheathed into the metal tube so that they can come into close contact with each other. In brief, the metal collar and the steel pipe hold the rubber tube in the center. I wonder if you understand. The outer diameter of the metal ring is about 111~119mm. It's hard to say how specific it is.
