FIELD: process engineering.
SUBSTANCE: invention relates to pipeline protection against corrosion and may be used in production of pipelines in various industries. In facing, polymer sleeve with adhesive compound is fed to be glued to tune inner surface by moving piston to produce tight chamber and fix said tube. Sleeve is pressed against tube inner wall by surplus pressure in produced chamber while gluing results from heating tube to adhesive compound polymerisation temperature. Polymer sleeve OD is selected equal to minimum tube ID with relevant allowance. Polymer sleeve inner surface is lubed with antifriction composition before facing process. Piston may be adjusted to outer diameter while tube is heated after complete pressure of sleeve to tube inner surface.
EFFECT: higher quality and facing and process efficiency.
