WPS Detail — Procedure record & validation findings

Qualified by PQR PQR-API-2026-103. Traceability established.

Base metal group P-No. 1 Gr.1 — API 5L X60 PSL2.

Joint is between identical P-Numbers — no dissimilar-metal restrictions apply.

Range 6–25.4 mm within qualified 1.5–25.4 mm for 12.7 mm test coupon.

Commercial range 6–25.4 mm is within conventional procedure limits.

Diameter statement “OD 406.4 – 1219 mm” compatible with SMAW root technique.

Preheat ≥ 100°C satisfies the 10°C minimum for P-No. 1 base metal.

Interpass 200°C within 315°C ceiling.

Thermal window 100–200°C is internally coherent.

PWHT not invoked — permitted for this material/thickness/code combination.

PWHT not required — cycle parameters not applicable.

PWHT not required — soak band check not applicable.

F-No. 3 (E6010 (root/hot), E7010-P1 (fill-cap)) is consistent with SMAW.

SMAW is flux-shielded; external shielding correctly marked N/A.

SMAW — backing gas not driven by process.

Flux process — flow rate not applicable.

DCEP polarity consistent with SMAW and E6010 (root/hot), E7010-P1 (fill-cap).

Amperage 70–120 A inside the SMAW operating envelope.

Voltage 22–28 V inside the SMAW operating envelope.

Travel speed 100–180 mm/min is plausible for SMAW.

Computed worst-case heat input ≈ 2.02 kJ/mm (declared ceiling 2.5 kJ/mm) — no toughness restriction invoked.

Position 5G is a recognised EN ISO 6947 / QW-461 designation.

Transfer-mode variable applies to GMAW only (SMAW exempt).

SMAW is an admissible process under API 1104.

Impact regime not invoked for the declared thickness/application.

Tank-specific routing not applicable.

IBR statutory route not applicable to this scope.

Administrative header fields adequately populated for issue.

Group-No. split applies only when notch toughness is specified.
