Sharing the reply from the General Administration of Quality Supervision, Inspection and Quarantine regarding the “issue of qualification stamps for pressure vessels”
Thread Content
Question: General Administration of Quality Supervision, Inspection and Quarantine: Hello! In the EPC projects carried out by our company, the pressure vessel equipment was designed by XXX design firm. The date of signing the design drawings was July 2008; at that time it happened to be the period for renewing their design qualification license, yet their qualification seal was still valid within the permitted scope (the expiration date of that seal was the end of 2008), and it was this seal that was used on the design drawings. The number of devices is 45. In October 2008, the equipment users commissioned the manufacturing units to begin production, and by February 2009, some equipment was still under construction; at that time, the validity period of the design approval stamp had already expired. The boiler inspection agency in the location of the manufacturing unit stated that its design qualification seal is no longer valid, which prevents the equipment from leaving the factory. Is what the boiler inspection agency says correct? Thank you! Answer: For entities holding a design license, drawings that meet the requirements of laws, regulations, and standards and are designed within the scope of the license during its valid period can be used for the manufacture of pressure vessels. Note: On March 18, 2009, the topic I initiated regarding the \"qualification seal for pressure vessels\" received a response from the General Administration of Quality Supervision, Inspection and Quarantine. I really admire their skill; their answers are excellent! I am now uploading it to share with everyone. Please share your valuable suggestions!
What matters is not the reply from the headquarters, but whether your actual problem has been resolved Has the local pressure vessel inspection agency given approval?
For entities holding a design license, drawings that are designed within the scope of that license during its valid period and comply with relevant regulations, codes, and standards can be used for the manufacture of pressure vessels.
The answer is vague; I still can’t understand it. No matter how the inspection agency interprets this answer, it’s fine...
“For entities holding a design license, drawings that are designed within the scope of that license during its valid period and comply with relevant regulations, codes, and standards can be used for the manufacture of pressure vessels. ” This answer is amazing!
“For entities holding a design license, drawings that are designed within the scope of that license during its valid period and comply with relevant regulations, codes, and standards can be used for the manufacture of pressure vessels. ” This should be a drawing designed within the valid period of the design license; it can also be used for manufacturing outside that period. However, when issues such as material substitution arise, which require intervention from the design department, things get quite complicated. I’m not sure if this is correct – I hope the experts can clarify it for me.
After reading it, I understood that the design must be valid within its design license period; the manufacturing aspect isn’t that important, right?
When will the endless word games stop? ! The fundamental issues are problems such as equipment quality and safety. The boiler inspection agency should put itself in the companies’ shoes and think about finding solutions. . . Looking forward to it. . .
Due to the tight schedule, without waiting for a response from the General Administration of Quality Supervision, Inspection and Quarantine, the design firm was asked to redesign the drawings and send them to the manufacturing unit. Done!
The design must be within the validity period of the design license
