Repair and Calculation of Balancing Beam Lifting Lugs of an Air Separation Equipment
Corrosion occurred in the area enclosed between the lifting lugs of the balance beam of a certain air sepa-ration equipment and the reinforced plates on both sides due to water accumulation.This paper uses the allowable electric power method to perform linear structural calculations on the balancing beam,and uses the finite element method to per-form non-static analysis for the lifting lugs structure.According to the calculation results,after the corrosion repair of bal-ance beam lifting lugs,the strength of the lifting lugs meets the usage requirements under the action of various working condition adapters(the original five types of designs).In addition,the repair plan and manufacturing and construction re-quirements for the balancing beam lifting lugs are provided.
