Method to control condenser clapboard deformation during erection

The erection of Unit 1 condenser clapboard in Shaoguan Power Plant is of strict precision requirements,heavy welding workload and great difficulty in controlling welding deformation.By improving the erection method of condenser clapboard and strictly implementing the welding codes and rational welding sequence,the welding deformation is strictly controlled to ensure the concentricity of clapboard tube holes within the designing allowance,and to shorten the time of threading tubes into the clapboard.The method is of referential value to the erection of condenser clapboard.
