Title: Lining sewage pipe with thermoplastics - by placing extruder in pit at one end of pipe, extruding thin-walled tubing inside pipe and pressing it against pipe with compressed air
Inventor: ABELER AXEL DIPL ING
IPC: B29C48/09
Filed: 1990-12-13
Abstract: Pipes lined with thermoplastics are produced using pipes whose i.d. holds the plastic material which is applied in the form of tubing and is bonded to that i.d.
