Metal-containing polymeric reinforced pipe, method for manufacturing same and pipeline produced using said pipe

A method for producing a metal-polymeric pipe by extrusion molding, comprising the steps of:

• feeding a polymer melt from an extrusion head into a mold cavity being comprised of a heat-resistant non-metal bush, a mandrel after the bush, and an external mold barrel around the bush and said mandrel;
• welding a metal reinforcing framework comprised of longitudinal reinforcement elements and transverse reinforcement elements, the step of welding being comprised of:
• coiling said transverse reinforcement elements around said longitudinal reinforcement elements;
• constantly pressing said transverse reinforcement elements to said longitudinal reinforcement elements by a roll electrode with a force applied by a hydraulic actuator;
• and
• synchronizing mutual crossing of said longitudinal reinforcement elements and said transverse reinforcement elements with pulses to said roll electrode;
• simultaneously feeding of said welded metal reinforcing framework into said mold cavity so as to form a molded pipe;
• and
• cooling an internal surface of said molded pipe within said molded cavity and after the bush, and after said molded cavity, and an external surface of said molded pipe after said molded cavity so as to produce a polymer matrix with a molecular structure based on an amorphous phase.
