Service Defects and Assessment of their Influence on Strength of Pressure Vessels and Pipelines in Petroleum Processing Production Systems
Equipment operation in petrochemistry inevitably leads to defect initiation, in particular in pressure vessels and pipelines. The most widely spread defects are erosion-corrosion and crevice shallow wall thinning. Assessment of the influence of such defects on load-carrying capacity of structures is a highly urgent task. The paper presents the results of many years of research in this direction, performed in the USA and in Western Europe. Here, the determinant factor at assessment of strength of structures with such defects is the maximum value of wall thinning, irrespective of the thinning zone dimensions. E.O. Paton Electric Welding Institute proposed procedures of assessment of the strength of structures with surface thinning, allowing for the length, width and varying depth of the thinning zones. It is experimentally established that the design (calculated) strength of the structure can be ensured at certain values and ratios of these characteristics. A procedure based on fracture mechanics principles is also proposed. Investigations are in progress now.
