FIELD: construction.
SUBSTANCE: invention relates to pipes with an inner protective coating and is designed for construction of pipelines from them to transport aggressive media. In a pipe with an inner protective coating and bushings from corrosion-resistant steel the latter cover some of the inner protective coating of the pipe and are fixed inside ends of the pipe by means of their distribution or clamping of the pipe ends. Connection of inner ends of bushings from corrosion-resistant steel with ends of the pipe is sealed by means of their adhesion between each other or placement of an elastic resilient sealing material between them.
EFFECT: invention increases reliability of protection against corrosion of an area near a seam in pipe connections in a pipeline.
