Based on the application status of the ship pipe processing technology database system, it is proposed to build a ship pipe processing technology database system to improve the management and control of the pipe production data and quality data. The overall design of the pipe processing technology database system is studied, the technological process of pipe processing is sorted out, the pipe fitting family is assembled and split, and the pipe processing production line of large, medium and small pipe fittings is designed. Through the on-site implementation and application, it is found that the process database system can standardize the BOM management of pipe fittings and refine the working hours
