摘要 |
In a method for manufacturing a thermoplasic pipe (46) a pipe-shaped blank having larger wall thickness and less diameter than the completed thermoplastic pipe is positioned in a cylindrical chamber. The blank is formed by being softened and expanded into engagement with the inner surface of the chamber. A sealing ring (64) is then mounted in an end portion of the plastic pipe by positioning the sealing ring in the expanded blank and shrinking the blank around the sealing ring by heating the pipe end portion (52). <IMAGE> |
