Discussion On Sealing Problems Of Ductile Iron Pipe Interface

- Jun 14, 2017-

Ductile iron pipe each pipe interface must undergo a sealed experiment to ensure that the plastic or spherical ink pipe interface in operation, add miscellaneous a quantitative pressure standards, but also to seal it.
Then the maximum clearance of the socket ductile iron pipe after docking should be between Be, so that it can be machined on the inside surface, this can meet customer requirements of the wall thickness. In the socket interface for sealing test, the socket part Ngawang more than twice times the inner diameter of the ball ink tube, the design of the wall thickness should be 0 to 10%, to meet customer requirements of the wall thickness. Comply with Iso10804 regulations.
