Seek advice on the three inspections and four fixations for equipment
Thread Content
I would like to ask about the concept of \"three inspections and four fixations\" for equipment. Specifically, those practices used by production units, as well as any recommendations for improvements related to construction work, covering both moving equipment, stationary equipment, and pipelines. It shouldn’t be something too technical that only supervisors can understand; it should be something that operators can easily check. It would be best if there were summarized guidelines or reference standards available. Thank you to those who know more on this topic

Check for design omissions: Conduct a final review of the design and construction drawings based on the actual conditions on site, to determine whether there are any design omissions that require additional design work or improvements ； Check the construction quality: First, verify whether the installation of process equipment and pipelines is in line with the design drawings, then conduct a thorough inspection of the overall appearance quality. Any issues that require correction should be identified in writing and immediate action taken to address them. For the internal inspection of construction quality, it is required to check the quality certificates of the installation materials and welding materials, the welding procedure qualification reports, the non-destructive testing reports for pipe welds, and the reports on the purging and pressure testing of the pipeline system ； Check unfinished projects: Conduct on-site inspections to identify which items are supposed to be completed according to the construction schedule but have not yet been finished. Define the process: A detailed, accurate, and feasible manufacturing process must be established, with every detail taken into account during implementation. Formulate plan measures: Based on the process flow diagram, develop a plan that includes each piece of equipment and each pipeline. Designate operators: Determine the organizational structure and operators to ensure unified planning and command. Set a time: Determine the specific date and time.

I don’t think there’s a fixed format for this, right? Whenever any issues are identified, they can all be listed. These issues include those that do not comply with standards, those that make operations difficult, those that hinder inspections, and those that pose safety risks – all of them can be brought up
