How should the process for pressure vessels be carried out?
Thread Content
I have switched from the chemical engineering field to equipment engineering, focusing on pressure vessel manufacturing processes. Half a year has passed in the blink of an eye, and it seems that all I’ve learned are those inspection standards listed in document 150; the processes I’ve mastered don’t seem to be useful for guiding production. I would like to ask experienced colleagues: how should a professional pressure vessel manufacturer prepare its process documents? How should part drawings and dimensions be created? Is it necessary to draw diagrams including welds before cutting the materials? Please share your thoughts on this matter. Thank you
I work in pressure vessel manufacturing as well; the workshop technicians all have their own processes
1. Check the technical specifications to see if there are any special manufacturing requirements. 2. The layout diagram for cutting the sheet metal, with notes indicating the locations of the openings for the connections. 3. Arrange the process flow and specify the manufacturing and inspection requirements. 4. Prepare drawings for the pressure testing equipment; if such equipment is not available, new drawings must be created. 5. Compile welding procedure cards and welding specifications.
1. Pattern review； 2 Make a budget, list of materials used ； 3. Structural manufacturing process: requirements for the dimensional specifications of components, requirements for the main manufacturing steps (materials, marking, cutting, inspection, welding, inspection, heat treatment…), assembly process ； 4. Develop welding procedures: Prepare weld layout diagrams, welding procedures, and inspection procedures ；
