FIELD: process engineering. ^ SUBSTANCE: set of invention relates to metal forming and can be used for fluid forming of articles. Proposed line comprises roll unwinder to unwind steel strip from reel, strip bending machine to bend steel strip into tube, welding head to weld strip edges together, fluid forming plant with mold that can be opened to receive ready tube after its forming and welding, and cutting unit to cut ready article after it is discharged from said fluid forming plant. There are also devices to seal tube, arranged on tube both ends, and device to feed fluid through one of said seals. Fluid forming is performed directly at said production line. ^ EFFECT: simplified process and reduced costs. ^ 4 cl, 3 dwg |
