The development of the oil and gas industry is solely related to the development of new northern territories of the Russian Federation. The development of deposits in permafrost conditions dramatically increases the cost of construction, primarily foundation work. One of the ways to reduce the cost of construction is to abandon the post-welding heat treatment of welded joints of straight seam welded microwave pipes. The paper presents the results of studies of mechanical properties, corrosion resistance, crack resistance, and fatigue tests confirming the possibility of eliminating excessive heat treatment.
