HIGH DEFLECTION UNRESTRAINED PIPE JOINT

摘要

The present disclosure generally pertains to systems and methods for an improved pipe joint. The system includes a first pipe having a bell socket end and a second pipe having a male or spigot end. The bell socket end of the first pipe is configured to include an inner groove within which a sealing member may be inserted. The bell socket end of the first pipe further includes a pivot cavity. The spigot end of the second pipe may be inserted into socket end of the first pipe to form an unrestrained, push-fit, ring-seal assembly when operatively joined, such that a sealing member is located within the inner groove, the sealing member having a sealing surface that is longitudinally related with the pivot point of the two pipes thereby allowing a high joint deflection angle while maintaining a relatively small pipe bell and sealing member mass.

主权项

1. A pipe joint comprising:
a first pipe having a bell end and a longitudinal axis, the bell end including an annular groove, an annular compressible member located within the annular groove, the annular compressible member having an inner face defining an opening, a second pipe having a spigot end with an outer diameter, the second pipe being inserted into the bell end and through the opening and pivotable relative to the first pipe, an annular seal formed by and between the annular compressible member and the spigot end, and a pivot point about which the second pipe pivots relative to the first pipe, the pivot point being coincident with a pivot plane extending perpendicularly through the longitudinal axis of the first pipe and through the annular compressible member.
