摘要：
An attempt is made to take into account the effect of a technological defect - the displacement of edges - in determining the bursting pressure in petrochemical apparatus. formulas are obtained establishing the quantitative relation between the general stress concentration coefficient and geometric parameters of a welded joint/displacement of edges and seam width), as well as stress concentration coefficients at different stages of deformation. Based on the formulas obtained, permissible standards for the displacement of edges are recommended taking account of the geometrical shape of the apparatus and the layout of welds.
