FIELD: pressure vessels. ^ SUBSTANCE: plastic-coating metallic vessel comprises outer load-bearing plastic shell and inner thin-walled welded steel shell whose intermediate section is cylindrical, two bottoms, and connecting pipe. The connecting pipe and at least one of the bottoms are made in block. The method comprises rolling out the rod from its one end thus defining the flange having flat circular surface from one side, working the unrolled section of the rod to form the outer surface and inner passage of the connecting pipe, rotating tension of the flange, moulding the bottom of a given shape, connecting the bottom to the intermediate cylindrical section, and welding the parts. ^ EFFECT: reduced labor consumption. ^ 4 cl, 3 dwg |
