FIELD: process engineering.
SUBSTANCE: proposed method comprises introducing a hose made in modified thermoplastic polymer inside the pipe and its subsequent heating. Cross section of aforesaid polymer hose is at least 10% smaller than the pipe ID. Note here that aforesaid hose has its diametre increasing in heating to size 10% larger than pipe ID.
EFFECT: simplified procedure, higher quality of pipe inner surface coat.
