A method for manufacturing a polymeric container comprising forming a polymer shell, in which the shell, bottom, neck, nozzles for inlet and outlet of water and aggressive substances, inlet and outlet of coolant or heat carrier of a body are made of a heat-resistant polyethylene PE-RT. In this case the shell and neck are made in the form of a spiral-welded pipe of large diameter wound from one, two or three layers of a pressure tube, the bottom - in the form of a single-layer welded flat spiral, nozzles for inlet and outlet of water and aggressive substances, inlet and outlet of coolant and heat carrier of the body - from pressure tubes. |
