METHOD FOR PRODUCING STRIPS OF OFF-GAUGE LENGTHS OF PIPE Russian patent published in 2016 - IPC B21B1/26 

Abstract RU 2579856 C2

FIELD: recycling.

SUBSTANCE: invention relates to methods for recycling unmeasured pipe ends preferably stainless steel. Method includes a breaker for the mother tube measuring and unmeasured sections, rolled sections into a flat profile. Preparation commercial product without the use of energy-intensive processes provided by the fact that the off-gauge lengths to form a flat profile is rolled into a barrel with a smooth rolls to obtain a strip with double reduction ratio λ, which is defined by the formula 1 < λ < Lmin/L0, wherein Lmin - minimum permissible length of commercial rental; L0 - off-gage length of the original length. Resulting dual band single strip is divided into segments of cut edge. Cut edge is drawn to give a wire.

EFFECT: obtaining a commercial product without the use of energy-intensive processes.
