Pipe gasket with selective economy of scale |
摘要 |
A pipe sealing gasket is shown which is designed to be received within a groove provided within a socket end of a thermoplastic pipe in a pipe sealing system. The sealing system includes a male, spigot pipe end which is joined to a mating female belled pipe end. The belled pipe end has an internal groove adjacent a mouth region thereof which is simultaneously formed under temperature and pressure as the mouth region is forced over a forming mandrel and about a sealing gasket located on the forming mandrel so that the sealing gasket is prelocated within the internal groove. The sealing gaskets of the invention have a sealing capability to seal volume ratio which is numerically related to the same sealing capability to seal volume ratio of prior art gasket designs by a multiplying factor of 2:1 or more.
