High-Pressure Sour Service Ready: Haihao Group Dispatches ASME B16.9 ASTM A234 WPB Fittings to UAE
Haihao Group has completed the dispatch of a large-volume consignment of carbon steel butt-weld pipe fittings tailored for an oil and gas infrastructure expansion project in the United Arab Emirates (UAE). The shipment encompasses both seamless and single-seam welded construction, including 45° and 90° long radius elbows, concentric and eccentric reducers, and reducing tees specifically conditioned for sour service environments.
Delivery Manifest & Engineering Specifications
Partnering with an established ASME B16.9 ASTM A234 WPB fitting manufacturer guarantees exact wall thickness matching, smooth back-arc transitions, and compliance with high-yield pressure vessel codes. Below is the technical specification of the cargo delivered to the UAE:
45° Long Radius Elbows (Seamless & Welded): 0.75″ to 8″ (SCH 30, SCH 40, SCH 80, SCH 160) seamless, and 24″ & 36″ SCH 20 single-seam welded | ASTM A234 WPB / WPB-W | Standard: ASME B16.9 | Sour Service.
90° Long Radius Elbows (Seamless & Welded): 0.75″ to 8″ (SCH 30, SCH 40, SCH 80, SCH 160) seamless, and 30″ SCH XS & 36″ SCH 20 single-seam welded | ASTM A234 WPB / WPB-W | Standard: ASME B16.9 | Sour Service.
Concentric & Eccentric Reducers: Concentric 2″ x 1″ & 2″ x 1.5″ (SCH 160); Eccentric 1″ x 0.75″ (SCH 80), 4″ x 3″, 6″ x 3″, 6″ x 4″ (SCH 40), 2″ x 1″ (SCH 160), 24″ x 18″ (SCH 20), and large-bore welded 30″ x 24″ (SCH XS x SCH 20) | ASTM A234 WPB / WPB-W | Standard: ASME B16.9 | Sour Service.
Reducing Tees: 2″ x 1″ (SCH 160 x SCH 160), 4″ x 2″ (SCH 40 x SCH 160), and 10″ x 4″ (SCH 30 x SCH 80) | ASTM A234 WPB | Standard: ASME B16.9 | Sour Service / Standard Service.

Sour Service Metallurgy & Quality Assurance Protocols
Upstream oil and gas pipelines transporting wet hydrogen sulfide (H₂S) require rigorous material controls to eliminate risks of hydrogen-induced cracking (HIC) and sulfide stress cracking (SSC). Every component forged by our ASME B16.9 ASTM A234 WPB fitting manufacturer facilities undergoes normalized heat treatment and strict chemical composition control to keep hardness levels well within sour service specifications.
For heavy-wall and large-diameter welded fittings (including 24″, 30″, and 36″ items), critical quality control measures were applied:
Back-Arc Thickness Control: Maintained a minimum 87.5% nominal wall thickness along back-arc bend radii to preserve pressure containment safety factors under high flow velocity.
Non-Destructive Examination (NDE): 100% Magnetic Particle Inspection (MPI / MT) and surface shot blasting were executed across all welded tee crotches and reducer seams.
100% Radiographic Testing (RT): Longitudinal seam welds were fully radiographed to ensure zero volumetric defects prior to surface painting.
Export Packaging & Logistics Protection
As a trusted ASME B16.9 ASTM A234 WPB fitting manufacturer, Haihao Group enforces heavy-duty preservation protocols for international maritime shipping:
All carbon steel fittings received a black rust-inhibiting coating to guard against ocean salt mist and humidity during transit.
Beveled ends (BW) were fitted with heavy-duty plastic protectors to safeguard welding margins during transportation and field unloading.
Delivered with EN 10204 3.1 Mill Test Certificates covering heat analysis, mechanical tensile and impact testing, NDE reports, and sour service compliance documentation.
Working alongside a verified ASME B16.9 ASTM A234 WPB fitting manufacturer streamlines procurement for complex Middle Eastern pipeline installations.
