Description

Примен емые способы сварки труб 1на станах спиральной сваркп не обеспечивают возможности изготовлени  труб ,с незначительной толщиной стенок.The methods used for welding pipes 1 in spiral-welded mills do not provide the possibility of producing pipes with a small wall thickness.

Описываемый способ изготовлени  сварных труб со спиральным швом путем нг вивки спирали из ленточной заготовки и сварки спирального шва позвол ет получать трубы с весьма тонкими стенками.The described method of manufacturing welded pipes with a helix by ng winding a helix from a band blank and welding a helix weld produces pipes with very thin walls.

Достигаетс  это применением роликовой контактной сварки вместо злектродуговой, причем, с целью повышени  производительности и улучшени  качества труб, на ленточной заготовке заранее или перед сваркой /производ т отбортовку кромок, а затем сваривают их.This is achieved by using roller contact welding instead of arc welding, and, in order to increase productivity and improve the quality of the pipes, on the strip blank in advance or before welding / flanging of the edges, and then they are welded.

Лента после стыкосварочной по.ступает на загибку кромок под пр мым углом к поверхности ленты, что осуш,ествл ют в клет х дуо с промежуточными энджерными валками.The tape after the welding seam starts to bend the edges at a right angle to the surface of the tape, which is dried in duo cages with intermediate angler rollers.

После этого ленту на формовочном стане сворачивают в трубу со спиральным расположением зазора между кромками, которые подвергают роликовой контактной .сварке.After that, the tape on the forming mill is rolled into a pipe with a spiral arrangement of the gap between the edges, which are subjected to roller contact welding.

Загнутые и сваренные кромки прижимают к стенкам трубы в правильно-калибровочном стане на роликовой оправке, ролики которой расположены по винтовой „шнии, причем угол наклона оси роликов к оси трубы равен углу наклона шва.Curved and welded edges are pressed against the pipe walls in a proper calibration mill on a roller mandrel whose rollers are located along a screw line, the angle of inclination of the axis of the rollers to the axis of the pipe is equal to the angle of inclination of the seam.

При необходимости иметь трубу с несогнутыми кромками загибани  кромок не производ т.If it is necessary to have a pipe with unbent edges, the edges are not folded.

отличающийс  тем, что, с целью повышени  производительности и улучшени  качества труб, на ленточной заготовке заранее или перед сваркой делают отбортовку кромок, а отбортованные кромки сваривают методом роликовой контактной электросварки.characterized in that, in order to increase productivity and improve the quality of pipes, strip flanging is made on the strip blank in advance or before welding, and flanged edges are welded by the method of roller electric welding.
