Abstract

1275379 Applying layers to pipes UKRAINSKY NAUCHNO-ISSLEDOVATELSKY I KONSTRUKTORSKY INSTITUT PO RAZRABOTKE MASHIN OBORUDOVANIA DLYA PERERABOTKI PLASTICHESKIKH MASS REZINY I ISKUSSTVENNOI KOZHI 29 Oct 1970 51553/70 Heading F2P A process for embedding a layer of fibrous material 14 in a thermoplastic pipe 8 comprises the steps of applying the layer to the pipe, decreasing, by cold forming, the diameter of the pipe and layer, and heating the pipe to the soften the pipe material so that the layer presses on to the pipe and the pipe material fills the interstices of the fibrous material layer. The layer 14 is wound on to the pipe 8, which enters a watercooled tapered sleeve 9. The pipe 8 and layer 14 are then heated by an electrical heater 13 and are subsequently cooled by a water-cooled sleeve 11. The pipe 8 with the embedded layer 14 has its outer surface roughed. If the resisting forces due to diameter decrease of the pipe 8 cause slippage at the pulling means, which is situated after the final operational stage, the pre-layered pipe is provided with longitudinal ribs to reduce these forces.
