MAINTENANCE OF CORROSION FIRMNESS OF WELDED CONNECTIONS OF PETROWIRE PIPES AT LEVEL OF WELDED METAL
Work is devoted increase of operational properties of pipes. It is shown that for the petrowire pipes received by high-frequency welding, at certain modes послесварочной thermal processing it is possible to come into a structural fortune of welded connections and accordingly прочностные and corrosion properties of connections at level of welded metal. Requirements and standards of structure of the welded connections, providing high corrosion firmness of welded pipes are developed
