To connect a pipe spool between existing pipes with high accuracy for power plant constructions,a calculation approach which figures out appropriate cutting positions and angles of extra length areas of the spool has been developed.In this approach,center positions and axes of end surfaces are modeled numerically based on three-dimensional measurement of each pipe,and the appropriate cutting surfaces are calculated by geometric analysis of the models with considering for ease of cutting work at the construction site.This paper described a modeling method of pipes,a calculation algorithm of the proper cutting surfaces of the spool,and a verification result of the calculation.
