DF Steel Pipe Delivers Complete Integrated Pipe Fittings and Flanges Package to Kuwait Oil Company (KOC) for Oil Field Gathering System with Full MTC 3.1 Documentation and Positive Material Identification

DF Steel Pipe has successfully delivered a complete integrated pipe fittings and flanges package to Kuwait Oil Company (KOC) for a new oil field gathering system in northern Kuwait. The order included ASTM A106 Grade B seamless carbon steel pipes, ASTM A234 WPB carbon steel butt weld fittings, ASTM A105 forged carbon steel flanges (ANSI Class 300 and Class 600), ASTM A193 Grade B7 / A194 Grade 2H stud bolts with nuts, and spiral wound gaskets. All pressure-containing components were subjected to 100% Positive Material Identification (PMI) using handheld XRF analyzers in the presence of an SGS third-party inspector. Full EN 10204 Type 3.1 Material Test Certificates with chemical, mechanical, NDT, and PMI documentation were delivered for every item.

1. KOC Oil Field Gathering System — Integrated Supply Package Strategy

Kuwait Oil Company (KOC) is a subsidiary of Kuwait Petroleum Corporation (KPC) and manages Kuwait upstream oil production operations, including the giant Burgan field (the world second-largest oil field after Ghawar in Saudi Arabia), as well as the Raudhatain, Sabriyah, Minagish, and Umm Gudair fields. KOC crude oil production capacity of approximately 2.85 million barrels per day (2026) requires an extensive network of oil field gathering systems — the surface pipeline infrastructure that collects crude oil, associated gas, and produced water from individual wellheads and transports these multiphase fluids to gas-oil separation plants (GOSPs), central processing facilities (CPFs), and ultimately to export terminals at Mina Al-Ahmadi, Mina Abdullah, and Shuaiba.

The gathering system for which DF Steel Pipe supplied this pipe package is designed for a new development area in northern Kuwait, connecting approximately 40 new production wells to an existing central processing facility. The system operates at wellhead flowing pressures up to 600 psi and temperatures up to 85°C, handling crude oil with API gravity of 28-32°, H2S content up to 3 mol% (sour service per NACE MR0175), and CO2 content up to 2 mol%. The combination of sour service conditions, elevated temperature, and erosive sand production from unconsolidated sandstone reservoirs required careful material selection — ASTM A106 Grade B for general piping (with NACE MR0175 hardness limit of 250 HV10 verified by laboratory testing on representative samples), A234 WPB for fittings (with supplementary hardness testing per project specification), and A105 for flanges (with restricted chemistry for HIC/SWC resistance per NACE TM0284 when H2S partial pressure exceeds 0.05 psia).

2. Quality Documentation and Material Traceability for Middle East NOC Projects

Kuwait Oil Company, like other Middle East National Oil Companies (NOCs) including Saudi Aramco, ADNOC, QatarEnergy, and PDO, maintains exceptionally rigorous quality documentation and material traceability requirements for all pressure-containing components in its oil and gas facilities. These requirements, typically documented in project-specific Material Requisition (MR) and Supplementary Technical Requirements (STR) documents, include: (a) Full EN 10204 Type 3.1 Material Test Certificates for every item, signed by the manufacturer authorized inspection representative and countersigned by the third-party inspector (SGS in this case); (b) 100% Positive Material Identification (PMI) on all alloy steel components and a defined percentage (typically 5-10%) of carbon steel components, with PMI results recorded on individual inspection reports traceable to the component unique identification number; (c) Heat treatment records for all quenched and tempered components (e.g., A193 B7 stud bolts) including furnace charts demonstrating compliance with specified temperature ranges and hold times; (d) NDE reports for all components requiring supplementary non-destructive examination beyond standard specification requirements, including UT lamination checks on flange forging blanks and MT/PT on fitting and flange finished surfaces; (e) Full dimensional inspection reports for a defined percentage of components, demonstrating conformance to ASME B16.5 (flanges), ASME B16.9 (butt weld fittings), and ASME B16.11 (forged fittings) dimensional tolerances; (f) Preservation and packing inspection reports confirming that all components are adequately protected against corrosion and mechanical damage during ocean freight, port handling, and site storage in Kuwait harsh desert-coastal environment.

DF Steel Pipe demonstrated full compliance with all KOC quality documentation requirements on this order, with zero punch list items raised by the SGS inspector during final document review. This successful execution further strengthens DF Steel Pipe position as a qualified steel pipe and fittings supplier to Kuwait and the broader GCC oil and gas sector.
