摘要:
The invention relates to polymeric pipes reinforced with a metal casing, which are used for transporting oil and gas, acids, alkali products, drinking water and industrial water, and also in the transportation of aggressive and neutral pulps, for example, in the event of the underground leaching of rock. What is claimed is: a metal-containing polymeric reinforced pipe comprising a welded metal casing and a polymeric matrix having an amorphous-phase-based molecular structure. The metal-containing polymeric reinforced pipe is produced by extrusion molding with simultaneous feeding of a polymer melt and the reinforcing metal casing into the mold cavity, followed by intensive cooling of the internal and external surfaces of the pipe being molded. The technical result of the invention is an increase in the quality and endurance limit in the radial direction of the metal-containing polymeric reinforced pipe, with an increase in productivity of the process for manufacturing said pipe, and also an increase in the strength and technological effectiveness of a pipeline constructed from the pipes produced.
