METHOD OF PROTECTION OF INNER SURFACE OF PIPE LINE WITH POLYMER MATERIAL Russian patent published in 1998 - IPC

Abstract RU 2118742 C1

FIELD: civil engineering; protection of gas mains against corrosion and increase of their carrying capacity. SUBSTANCE: application of polymer material is effected by extrusion of material in viscous-flow state by means of thermomechanical module. Power supply and motion will be effected due to kinetic energy of gaseous agent transported via pipe line at pressure drop of from 0.05 to 7.5 MPa and rate of motion of thermomechanical module up to 1 m/min. EFFECT: extended of technology. 2 cl
