WELDING CONSUMABLES FOR PIPELINE SOUR SERVICE - SPECIAL REQUIREMENTS

Welding Consumables Sour service requirements: Sour service Welding Procedure Qualification test coupon needs to be and Impact Tested. Dissimilar Metal Welding (DMWs) are not permitted for any welds exposed to sour service (welds in clad systems are acceptable if the DMW interface with the ferritic steel is not in contact with the sour fluid). DMWs are permitted for non-sour hydrocarbon service if made with a nickel-based consumable. Austenitic stainless-steel consumables may be used only for the following applications and if the maximum design temperature is below 300°C: 1) External structural attachments (e.g., pipe supports). 2) Non-sour, non-hydrocarbon (e.g., water, air) services. 3) Hydrogen addition in the shielding gas is not permitted for DMW. Filler metal conforming to ER70S-6 shall not be used with GTAW process for sour service. If ER70S-6 is to be used with GMAW process for sour service, the chemistry of the wire shall not exceed the requirements of NACE SP0472 (as follows), This must be verified for all lots of wire. Carbon (C) 0.10 wt% max; Manganese (Mn) 1.60 wt% max; Silicon (Si) 1.00 wt% max. Local Standard: Filler metal or deposit chemistries conforming to A-number 2 (ASME SEC IX), i.e., carbon-0.5% Mo, (e.g., E7010-A1 or E7018-A1 for SMAW), shall not be used for sour service applications without post weld heat treatment. All electrodes shall be purchased with certified lot testing in accordance with AWS A5.01 or BS EN ISO 14344. The Lot classification shall be S2, T2, C2, F2 or higher. The schedule of testing shall be “4 or I” or higher for AWS A5.01 and “Schedule 4” or higher for BS EN ISO 14344. For sour service application, all welding related requirements of ISO 15156 shall be followed. Note that for sour service, carbon steel welding consumables containing more than 1.1% mass fraction nickel are not acceptable.
