For the nickel-based alloy UNS N06625, the chemical composition shall meet one of the classes given in table 8 Table 8 composition of the nickel-based alloy UNS06625 —Chemical For the nickel-based alloy UNS N06625, the chemical composition Fe 5 specification should be considered for equipment that remains subsea for prolonged times. Welds for use in hydrogen sulphide service shall conform to the requirements of ISO 15156 (all parts), NACE MR 0175. Application Post weld heat treatment: End and outlet connections with corrosion-resistant weld-overlaid ring grooves shall be subjected to post weld heat treatment in accordance with the WPS. Ring grooves for welding: Ring grooves for welding shall be prepared in accordance with API 6A, table 52. weld preparations: Other weld preparations may be used if the mechanical properties of the deposited weld metal equal or exceed those of the base metal. corrosion-resistant overlays other than ring grooves The provisions of section 10.2.4.2 apply to the use of corrosion-resistant weld overlay for bodies, bonnets, clamp hub end connectors, and end outlet connectors for the purposes other than API 6A standard ring grooves. The manufacturer shall use a written procedure that provides controls for consistently meeting the manufacturer-specified material surface properties in the final machined condition. As a minimum, this shall include inspection methods and acceptance criteria. Qualification be in accordance with Articles II and III of ASME Boiler and Pressure Vessel Code Section IX for corrosion-resistant weld metal overlay or hard facing weld metal overlay as applicable. Chemical analysis Chemical analysis of the weld metal shall be performed in accordance with the requirements of ASME. BPVC:2004, Section IX, at the minimum overlay thickness as specified by the remanufacturer, OEM or OPD holder for the finished component. Provisions for the chemical analysis of section 9.2.4.1.2 apply. Mechanical properties overlays Base metal shall retain the minimum mechanical property requirements after post-weld heat treatment.
