ASME B16.9 ASTM A420 WPL6 sour service elbows for UAE sour gas project

Haihao Group has finished fabrication, inspection and shipment of large diameter longitudinally welded elbows built for sour service, to meet the sour gas piping requirements of our UAE client. This shipment includes 36 inch SCH STD 45° and 90° long radius elbows, all manufactured as longitudinal seam welded components.

This ASME B16.9 ASTM A420 WPL6 sour service elbow is specified for harsh sour hydrocarbon environments, where resistance to hydrogen induced cracking is non-negotiable. Unlike ordinary carbon steel elbows for general utility lines, this ASME B16.9 ASTM A420 WPL6 sour service elbow follows sour service material controls, suitable for wet H₂S process piping common across UAE onshore and offshore gas facilities.

Sourcing large bore sour service elbows carries extra production challenges. The 36 inch size makes seamless forming impractical for many fabricators, so longitudinal welded construction is selected here. Each ASME B16.9 ASTM A420 WPL6 sour service elbow is formed, welded and inspected with extra focus on seam integrity, to satisfy project sour service acceptance criteria.

Our QA team tracks weld documentation, material traceability and required mechanical testing for every heat and weld seam. We ensure each ASME B16.9 ASTM A420 WPL6 sour service elbow comes with a complete document package ready for third-party review, which helps UAE EPC teams cut down site approval delays.

Many regional buyers struggle to find reliable suppliers for large bore WPL6 sour service elbows that combine ASME B16.9 compliance and proper sour service qualification. Haihao Group holds stable capacity for longitudinally welded large diameter elbows for sour gas service.
