Description

Известный способ изготовлени  тонкостенных труб со спиральными ребрами заключаетс  в закрутке тонкостенной трубы с продольными ребрами.A known method of manufacturing thin-walled tubes with spiral ribs consists in twisting a thin-walled tube with longitudinal ribs.

В предлагаемом способе дл  совмещении термообработки с деформацией и полут1ен л ьысокой точности по шагу спирали закрутку трубы с продольными ребрами осуществл ют с MecTHbiiM подогревом.In the proposed method for combining heat treatment with deformation and semi-low high precision in the pitch of the helix, the pipe is twisted with longitudinal ribs with MecTHbiiM heated.

Предлагаемый способ включает следующие олерации: прокатку «а стане ХПТР тонкостенной , термообработанной, ;протр  вленной и с соответствующим необходимым покрытием гладкой трубы на оправке дл  получени  продольных ребер и последующую закрутку с местным подогревом на закруточном стане дл  получени  трубы с винтовыми ребрами . Это позвол ет совместить процесс термообработки с деформацией и получить высокую точность niara спирали.The proposed method includes the following olerations: rolling a thin-walled, heat-treated mill; heat-treated, punctured and with the appropriate necessary coating of a smooth pipe on a mandrel to obtain longitudinal ribs and subsequent twisting with local heating on a twisting mill to obtain a pipe with helical ribs. This allows the heat treatment process to be combined with the deformation and to obtain a high precision niara helix.
