Technology and device for production of heightened quality pipes for arterial oil and gas conduits are created and inculcated on factual data of work of Novomoskovsk Pipe Plant. At present such pipes are made with using heat treatment in penetrated sectional stoves. Herewith big volume of natural gas is expended. Besides, it is observed an incomplete removal of residual stresses during heat treatment that adversely affects at operation pipe indexes and durability of welded seam. Researches, which authors have conducted, have shown that offered weakly annealing technology and device provide almost full removal of undesirable residual stresses that considerably raises durability of welded junctions and improves operation pipe indexes. Inculcation of offered technology in Ukraine at the same time will allow to reduce by 40-50 % natural gas expense, to raise ecological safety at the sacrifice of diminish of possible damages at conduits as well as to produce electric welded pipes of heightened quality. I am sending you the abstract of the report Elaboration and device complex trial for pipe production of heightened quality, reference number - IAC-02.V.6./1.7 - ? (Unfortunately number is lost. Please inform us the number of our report once again) authors Privarnikov J.K, Vdovin V.D., Privarnikova I.J. for presentation at the 53rd International Asnronautical Congress/ Professor Yu.
