Is it required that each fitting received for inspection be equipped with a certificate of conformity? (elbows, tees, crosses, flanges, valves, etc.)
Yes, usually, when receiving the pipe fittings, it is necessary to check whether each fitting comes with a certificate of conformity. Fittings such as elbows, tees, crosses, flanges, and valves all require corresponding certification documents. Only fittings that have undergone proper testing and meet the standard requirements can be used properly. Therefore, for incoming inspection, it is necessary to carefully check the quality of each fitting as well as its certification. .
Are you that idle? Signs don’t cost anything – put one on every place. The question is, do you check each one personally?:lol:lol:lol
Pressure pipeline components require material certification; ordinary components have fewer general requirements
Each fitting and pipe must be equipped with a certificate of conformity, while valves are hung on them
Does the standard require random inspections or full inspections for fittings before they leave the factory?
Here we are discussing petrochemical pipe fittings; which standards do the manufacturers of pressure pipeline fittings follow? Is there a licensing system? The TSG D2001 2006 document was invalidated in 2019, and it’s not clear what document replaced it. Furthermore, the standard followed by the construction unit responsible for the pressure pipelines on site determines the technical requirements for the incoming inspection (including the certificate of conformity). If the above two files are clarified, there will be a basis.
TSG D2001 has been replaced by TSG07-2019. In my opinion, the construction of pressure pipelines should comply with the relevant pipeline regulations, namely TSG D0001-2009 and Part 4 of the Pressure Pipeline Code GB20801-2020. In addition, industry-specific standards such as SH3501-2021 from the petrochemical industry should also be followed. As for the inspection of materials upon arrival, in addition to the aforementioned standards, it is also necessary to follow the procedure documents of the construction party’s pressure pipeline quality assurance system.

So, for pipe components (in my opinion, with valves being somewhat special), there is no requirement to attach a certificate of conformity to them in reality. . . Rather, it should have tracking marks that allow for tracing back to the quality certificate
