FIELD: construction.
SUBSTANCE: invention can be used in construction of pipelines from metal pipes with internal coating. Connection method of metal pipes with internal coating includes installation inside the pipe ends of bushing with sealing elements mounted on its outer surface and further pipe connection by welding. Connection comprises backing bush pressed with sealing elements and glue from thermoplastic compound applied on both sides from the middle part of external surface of the backing bush, thermoplastic material of adhesive coating is melted due to heat electric arc welding, distributed along the material of the backing bush and metal pipe ends, which is attached backing bush to inner surface of metal pipes with internal coating.
EFFECT: technical result consists in simplification of technology of connection of metal pipes with internal coating.
