  • Patent number: 7217379
    Abstract: A method for producing a tube section from thermoplastic material, in which a tube section is extruded by means of an extruder which is provided with an extruder die having an inner core, which inner core defines an axial hollow space in the tube section, the tube section coming out of the extruder die downstream of the extruder die being internally cooled by means of an internal cooling member and externally cooled by means of an external cooling device. Immediately after the tube section leaves the extruder die, the internal cooling member brings about internal cooling of the tube. The external cooling device is positioned downstream of the internal cooling member, so that the external cooling of the tube section is brought about after the internal cooling.

  • Patent number: 7069635
    Abstract: A method for forming an integral socket to a pipe made from biaxially oriented thermoplastic material is described. The pipe has a pipe body and is provided, at one or both ends, with an integral socket. The biaxially oriented thermoplastic pipe is subjected to a socket-forming operation comprising the steps of fixing both axial ends of the unheated end part of the pipe, heating the fixed end part to a suitable socket-forming temperature in one or more steps, and expanding the axially fixed end part with the aid of a fluid pressure in the interior of the end part and/or a vacuum on the outer side of the end part, which expansion may begin as early as during the heating of the end part.
