Corrosion of equipment in the oil and gas complex is a global problem, as it contributes to huge material costs and global disasters that violate the environment. Corrosion control methods used to protect equipment do not always ensure the absolute safety of the operation of oil and gas facilities. Moreover, they are quite expensive. The developed method for controlling the electrochemical parameters of aqueous solutions to combat complications during the operation of oil-field pipelines provides the necessary protection against corrosion. The method is economical and environmentally friendly, since it does not require the use of chemical reagents. The test results have shown a very high efficiency in dealing with complications in oil fields.

Liquefied natural gas (LNG) is of great importance in the energy segment of the economy. Natural gas, has a higher calorific value, better fuel efficiency and is more environmentally friendly, thereby gaining more importance compared to oil and coal. Not only does LNG offer greater flexibility in supply, it also has cost advantages for transportation starting from a distance of 2,000 km (at sea) and 4,000 km (on land) respectively. Consequently, the LNG market will grow in the coming decades compared to two other fossil sources - oil and coal. To use natural gas, it is necessary to create safe and economically profitable transportation routes from natural gas deposits to end users. One possibility is to transport gas in a liquefied state, at low temperatures. To ensure safe and reliable storage of liquefied gas at minus 163 ° C, good physical and mechanical properties of the base material and weld (corresponding tank system) are required. To meet these high requirements, appropriate welding methods and welding materials are selected. The paper presents an analysis of activities on the development of new welding materials and improvement of welding technologies for the construction of LNG tanks.

“…When the electrode potential is shifted from the optimal range of electrochemical protection -0.85... -1.15 V (by ppm), corrosion processes are significantly promoted. With a decrease in the absolute value of the potential, local corrosion (local, ulcerative) develops, with an increase -peeling of coatings and, as a result, penetration of an aggressive medium into the formed voids [13][14][15][16][17][18][19].…”

Corrosion damage to metal is one of the main factors that reduce the safety of operation of main pipelines. It is known that about 70 % of pipeline failures occur due to metal corrosion. Electrochemical protection in combination with non-metallic coatings is currently the main method to prevent aggressive effects of corrosive media on main pipelines. The use of these methods of protecting pipelines has a number of difficulties that can be associated with the use of several protective coatings of different types and conditions on one oil pipeline; use of cathodic stations of different design and efficiency; Lack of a system to monitor electrochemical protection objects; difficulties arising during operation of anode grounding electrodes and comparison electrodes. Under these conditions, bringing the technical condition of the anti-corrosion protection system of the main oil pipelines to the level corresponding to the modern requirement of industrial safety is an important task that allows improving the safety and reliability of pipeline transport facilities. The article provides an analysis of the operation of cathodic protection units of the Kaltasy-Yazykovo main oil pipeline and the results of calculations on optimizing the modes of the cathode stations.
