Abstract: Starting from the common quality control difficulties in petrochemical engineering design, this paper proposes the use of 3D collaborative design to solve the design quality problems. By analyzing the workflow of 3D collaborative design, this paper studies its systematic quality control methods in three stages in combination with its characteristics of digitalization, visualization and integration, including establishing and improving the rules in advance, strengthening inspection and verification during the process and implementing the quality records after the event. Taking SmartPlant Foundation as an example, this paper proves that the quality control methods of 3D collaborative design are effective in ensuring the integrity, reliability and consistency of design, and explores the innovation and development of quality management and control technology brought by 3D collaborative design
