Haihao Group Dispatches NACE-Compliant ASTM A234 WPB Tees to UAE
Haihao Group has completed the dispatch of a large-volume consignment of heavy-wall butt-weld tees for an oil and gas infrastructure project in the United Arab Emirates (UAE). The shipment includes both seamless and welded equal and reducing tees engineered to operate under high-pressure loads and sour gas environments.
Delivery Specification & Order Manifest
Sourcing from a certified NACE MR0175 ASTM A234 WPB tee manufacturer ensures precise dimension control and full metallurgical compliance with severe sour service standards. Below is the technical specification of the completed order:
Equal Tees (Seamless, BW, ASME B16.9): 1/2″ SCH XXS, 1″ SCH 160, 2″ SCH 160, 10″ SCH 120, and 10″ SCH 160 | ASTM A234 Grade WPB | NACE MR0175 / ISO 15156.
Reducing Tees (Seamless, BW, ASME B16.9): 2″ x 1″ (SCH 80 x SCH 160), 2″ x 1″ (SCH 160 x SCH 160), 6″ x 4″ SCH 120, 10″ x 4″ SCH 120, 10″ x 4″ SCH 160, and 10″ x 6″ SCH 120 | ASTM A234 Grade WPB | NACE MR0175 / ISO 15156.
Large-Bore Welded Reducing Tees (BE, ASME B16.9): 20″ x 8″ (33.32 mm x SCH 120) and 20″ x 10″ (33.32 mm x SCH 120) | ASTM A234 Grade WPB(W) | NACE MR0175 / ISO 15156.

Sour Service Metallurgy & Quality Assurance Testing
Upstream oil and gas processing facilities handling hydrogen sulfide ($\text{H}_2\text{S}$) require rigorous material controls to prevent sulfide stress cracking (SSC). Every NACE MR0175 ASTM A234 WPB tee in this order was manufactured under controlled chemistry parameters to guarantee compliance with ISO 15156 requirements.
To verify surface integrity and internal soundness on heavy-wall fittings—ranging up to SCH XXS and 33.32 mm wall thickness—components underwent thorough shot blasting followed by 100% Magnetic Particle Inspection (MPI / MT).
Surface Preservation & Export Packaging
As an experienced NACE MR0175 ASTM A234 WPB tee manufacturer, Haihao Group enforced comprehensive export preservation protocols before maritime transport:
Surface Treatment: All carbon steel tees received uniform shot blasting to remove mill scale, followed by application of protective anti-corrosion coatings.
End Protection: Beveled ends (BE) were fitted with heavy-duty plastic bevel protectors to safeguard welding margins during transit and field handling.
Certification & Traceability: Full EN 10204 3.1 Mill Test Certificates were issued, covering chemical analysis, mechanical property testing, NACE hardness limits, and MT inspection reports.
Working with an established NACE MR0175 ASTM A234 WPB tee supplier ensures seamless procurement for complex Middle Eastern pipeline projects.
