Ring pressure

Ring pressure pipe

Summary

Ring pressure connection definition:
A pipe mechanical connection method in which the pipe fitting together with the cylindrical rubber sealing ring and the stainless steel pipe are extruded inwards along the circumferential direction with a special tool.
Ring pressure connection principle:
The ring-press connection is a type of pipe connection in which special sealing rings, pipe fittings and pipe circumferences are extruded into a body with special tools. The cylindrical wide-band sealing ring is sleeved on the pipe, and the pipe is inserted into the pipe. The special tool applies pressure from the outside along the circumference of the pipe to make the pipe concave and deform and compress the sealing section of the pipe, so as to achieve the connection type of pipe and pipe fastening and sealing.
