One of the most common types of metal destruction in the oil and gas industry is hydrogen embrittlement. Hydrogen corrosion is a complex of negative effects of hydrogen on steel, leading to the destruction of metal structures. Hydrogen passes through a defect-free metal, without lingering in it. In the presence of defects, hydrogen is retained in the metal forming a brittle solid solution, metal stratification along the segregation streamer, blistering. Studies of the metal of a gas pipeline made of steel 09G2S are presented in the article. The sample was selected from the local zone of destruction in the condensate collector, the metal of the pipe had typical for hydrogen corrosion stratifications. The scope of the study was identification of the most dangerous part of hydrogen corrosion on the sample taken from the local zone of destruction. Studies on the chemical composition and mechanical properties of 09G2S steel were also carried out. Stress-related characteristics of the metal microstructure of the failed gas pipeline were obtained and the character of the destruction progress was revealed. The presence of sulfides cluster in the metal of studied pipe was determined applying metallographic method for determining nonmetallic inclusions.

Over the years of existence of the oil and gas industry, increasing the efficiency of equipment at production facilities places increasing demands on operational reliability and durability. The use of aluminum alloys is due to a large range of its features and properties, one of which is the combination of high strength in combination with low density, sufficient corrosion resistance, good moulding ability by casting, pressure and cutting, the possibility of using aluminum parts in all kinds of structures by welding, soldering and other methods. It is important to bear in mind that aluminium alloys do not require regular corrosion coating during operation. It is all about the finest and extremely strong oxide film (0.00001 mm), which forms a reliable adhesion to the metal.

“…A fairly large number of works are currently devoted to the problem of investigating the occurrence of damage in the coils of tubular furnaces and ensuring reliable and safe further operation of them. [1][2][3][4][5][6][7] Most often, various damages and deviations are observed in coils that are operated in radiant chambers. Simultaneous exposure to overpressure, elevated temperatures, working medium, etc.…”

The coils of radiant chambers of tubular furnaces are operated under especially loaded conditions in terms of temperature stress distribution. It is in the radiant sections that the feed is heated to the required maximum temperatures. Also, part of the coil structure may be in close proximity to the burners and exposed to an open flame to form superheating zones. In this regard, the elements of the coil can deform and prematurely collapse. One of the most important roles is played by the support elements of the coil in the form of suspensions, brackets, etc., which serve to prevent sagging of the coil pipes. An important role is played by the optimal location of the support elements of the coils during design in order to prevent pipe sagging during operation. In the era of rapidly developing digital technologies, the problem of optimal location of support elements at the coil, taking into account the peculiarities of the design, operating parameters, and the intensity of thermal radiation, can help solve specialized software complexes. Special programs develop a coil model taking into account all the necessary parameters and characteristics, both material and technological process. This makes it possible to detect zones of concentration of increased stresses and maximum deformations. Therefore, the actual work is the modeling of the stress-strain coil of the radiant coil, taking into account the different locations of the support elements.
