In order to improve the management and control of pipe fitting production data and quality data in shipyards, it is proposed to construct a ship pipe processing technology database system. The overall design of the pipe processing technology database system is studied, the pipe processing technology flow is sorted out, and the pipe fitting assembly process is improved. Through the practical application in shipyards, the ship pipe processing technology database system realizes the management standardization of pipe fitting Bill of Material (BOM) and the refinement of working hours, which can effectively improve the production efficiency in shipyards and meet the expected requirements of enterprises.
