Deformation prevention method for large-scale stainless-steel tank wallboard construction under high temperature environments

The invention discloses a deformation prevention method for large-scale stainless-steel tank wallboard construction under high temperature environments. The method is characterized in that the methodincludes the following steps: a, a step of deformation prevention during the making of steel plates of tank wallboards; b, a step of deformation prevention during the welding operation of the tank wallboards; and c, a step of the arrangement of expansion rings for tank jacking. The characteristics of the method are that the wallboard welding under high temperature, high humidity and blown sand environments has longer stress release time than usual welding. The advantages of the method are that welding technologies are rigorous in measure design, and deformation prevention for tank wallboard construction is rigorous; welding stress release modes can be successfully buffered after tank wallboard welding construction is finished; welding deformation caused by releasing can be avoided; weldingquality of the tank wallb
