FIELD: civil engineering. SUBSTANCE: method is used for construction of pipelines with internal protective lining. Metal pipes with internal coating are set on sealing cylindrical bushing. Then squeezing cylindrical coupling is mounted on butt joint of pipes from external side with lateral sides of coupling positioned from different sides of butt joint, and subsequent reducing of coupling from one end of coupling to the other is performed. External surface of sealing cylindrical bushing has projections and groove in the middle, and internal surface of squeezing cylindrical coupling is provided with thread and/or grooves. Prior to setting of pipes on sealing bushing, sealing material is placed in its groove, and during assembly groove is positioned at place of butt joint of metal pipes. EFFECT: enhanced reliability of pipeline. 1 dwg
