Abstract
The paper describes typical cases of failure of elements of oil refining equipment, including the destruction of welded joints made by austenitic electrodes, furnace coil pipes cracking, hydrogen cracking, metallurgical cases and corrosion. The causes of destruction and depressurization are classified with the identification of the main problems and the relations between them.
Highlights
The modern oil refining industry is characterized by the use of powerful power plants and process fluids with high corrosion activity
An important step in determining ways to solve this problem is to conduct a comprehensive analysis of the accident rate of oil refining equipment, identifying common types of damage and critical factors that affect it
As a result of the studies, it was found that the accident rate at oil refineries is determined by two groups of reasons: technological and operational
Summary
The modern oil refining industry is characterized by the use of powerful power plants and process fluids with high corrosion activity. Increasing the reliability and service life of equipment in order to increase safety and optimize economic resources is always an urgent task. An important step in determining ways to solve this problem is to conduct a comprehensive analysis of the accident rate of oil refining equipment, identifying common types of damage and critical factors that affect it. One of the regularly arising problems is the destruction of welded joints of pipe fragments of steel 15Cr5Mo (AISI 501 analog) made by austenitic electrodes. The determining conditions for the occurrence of brittle fractures are factors of heterogeneity and deterioration of the properties of certain zones of such welded joints [1, 2]
