Why isn’t there even anyone to reply? I’ll reply myself:P
As a reference, for the final closing weld of the equipment in the field of equipment engineering, if RT testing is not possible, then testing may be omitted; however, shims must be used. If testing is required, then PT or MT testing can only be employed. There’s also a last-ditch option: insert a pair of flanges. Haha
Both RT and UT are comprehensive methods for inspecting weld quality, and neither can replace the other. A pressure pipeline installation report must include either RT or UT; therefore, if neither method can be used, the inspection cannot be completed successfully. The TSGD7006-2020 \"Rules for Supervisory Inspection of Pressure Pipelines\" issued on May 16 provides detailed instructions.
