Scope

Scope: This document specifies the penetration testing method for the surfaced weld overlay and the base material within a 13-mm range around it, as well as the testing personnel, penetration testing agents, testing timing and conditions, testing procedures, safety requirements, quality acceptance, and testing reports. This document is applicable to the detection of surfaced weld overlay on the inner and outer surfaces of oil extraction tree components with an inner diameter greater than 50mm. The detection of the outer surface of other oil extraction tree components (such as gate valve flaps, valve seats, and valve stems) before surfacing can be carried out in accordance with this document.
