Issues regarding the inspection reporting for pressure vessels and pressure pipelines
Thread Content
Hello everyone, I have a question regarding the inspection fees for pressure vessels and pressure pipelines: We hired a company with GC1 certification to install a small device in our laboratory. In their detailed quote, the cost for the inspections of these pressure vessels and pipelines totaled 40,000. Do you think this amount is too high? I looked for the relevant fee details at the Shanghai Special Inspection Institute. Our pressure vessel is relatively small, with a volume of 150 L and a design pressure of 17.13 MPa; it seems to cost only a few thousand yuan? As for pressure pipelines, ours are DN40 in size (actually, according to the new regulations, there’s no need to submit them for inspection?) ), the total length is only 71m. What are the items included in the inspection requirements for pressure pipelines? I saw a document titled \"Charges for Inspection of Maintenance and Renovation of Pressure Pipelines\" and another titled \"Charges for Regular Inspection of Pressure Pipelines\". I’m not sure how these inspection fees are calculated Could those who are aware of the situation please help explain it? Thank you.
Could the original poster share these two pricing standards? Where was it found~
The inspection costs mainly involve flaw detection of the weld joints and pressure testing for leaks. Only pipelines with a diameter of DN50 or larger qualify as pressure pipelines. You can ask the construction party to provide a detailed list of the costs, or you can consult the local Quality and Technical Supervision Bureau’s special inspection institute
