FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Proposed plant comprises furnace for heating the ingots to ductility temperature, roll table for ingots transfer, helical rolling mill for broaching the ingots to hollow sleeves, two trolleys to transfer said sleeved to Pilger mill, roll tables, hot cutting saws to cut off Pilger heads and seed ends, drag to transfer articles to finishing station, straightening presses, tolls for cutting pipes to lengths, inspection stations, repair sections and acceptance sections. Stationary troughs are installed behind every stand, their semicircular diameters being specified. Note here that feeder with long mandrel are arranged at inlet of the first Pilder stand. Pilger mill is arranged behind said helical rolling mill with at least three Pilger stands spaced apart on one axis.
EFFECT: higher efficiency, lower metal input and costs.
