FIELD: process engineering.
SUBSTANCE: invention relates to pipe rolling. This process comprises crosswise welding of pipe billets. Assembly-line production of these pipes comprises coiling sheet or roll strips on spinning reel their length being specified by mathematical relationship. Then, strip edges are welded together in radius from pipe billet outer surface to its inner surface. Then, after removal of coiled pipe billet from said reel, strip outer and inner edges are welded to pipe billet. Proposed plant comprises reel, reel drive, gear stand, stationary case, pipe billet removal lever displacing in horizontal plane, lever drive with worm reduction gear, cover with thrust bearing, unit for radial and lengthwise welding of pipe biller plies, feed roll table with straightening- tensioning device, prism for fitting strip rolls, draw-off roll table and crosswise butt welding means. Note here that said reel has driven and idle journals. The former is engaged via reduction gear with the drive while the latter is engaged with the cover. The latter is coupled with stationary case accommodating the thrust bearing. Groove is made in outer diameter of said reel.
EFFECT: lower costs and metal input.
