Inspection specifications

I don’t understand the requirements for flaw detection – what are the relevant standards and regulations? Seeking advice from experts
GB/T150.2-2011, GB/T150.4-2011, \"Safety Inspection Regulations for Fixed Pressure Vessels\", NB/T47013-2015
SH 3501-2011 Code for Construction and Acceptance of Steel Piping Systems for Toxic and Flammable Media in Petrochemical Industries, as well as GB50517-2010 Code for Quality Inspection of Metal Piping Systems in Petrochemical Industries; in addition, it is necessary to take into account the pipe grade specified in the pipeline diagram provided by the design institute and the medium flowing within the pipes.

Then, look up the relevant provisions regarding non-destructive testing in that standard; such standards generally include requirements for non-destructive testing methods (RT-100%, RT≥20%, UT, MT, PT, TOFT, etc.). Finally, examine the non-destructive testing procedure standards referenced by the execution standards.
For general requirements and specifications, one can refer to the NB/T47013-2011 series; the specific requirements shall be determined based on the technical specifications for manufacturing and acceptance as well as the design drawings – there are many standards available.
