Sour Service Pipeline Integration: Haihao Group Delivers ASTM A105N Branch Outlets to UAE

Haihao Group has completed the dispatch of a multi-component high-pressure piping order engineered for a critical onshore sour service development in the United Arab Emirates (UAE). Combining normalized carbon steel integrally reinforced branch outlets, high-pressure forged plugs, and specialized swage nipples, this shipment provides robust branching and flow transition capabilities under severe operating conditions.

Delivery Manifest & Technical Specifications

Sourcing from a certified MSS SP-97 ASTM A105N branch outlet manufacturer guarantees precise saddle contours, flawless bevel geometry, and total compliance with international piping standards. Below is the itemized manifest for the UAE consignment:

High-Pressure Hex Plug (ASME B16.11): 3/4″ Class 6000 Threaded Hex Head Plug | Material: Stainless Steel ASTM A182 Grade F316/316L.

Eccentric Swage Nipple (MSS SP-95): 4″ x 3″ (Branch Large End Beveled x Threaded Small End – BLE x TSE) | Wall Thickness: SCH 80 x SCH 160 | Material: ASTM A234 Grade WPB.

Normalized Carbon Steel & Sour Service Metallurgy

When pipeline systems handle hydrocarbon fluids containing wet hydrogen sulfide (H₂S), raw material soundness is essential to prevent hydrogen-induced cracking (HIC) and sulfide stress cracking (SSC). Every forged fitting manufactured by our MSS SP-97 ASTM A105N branch outlet manufacturer plant was forged from normalized carbon steel stock.

The normalized heat treatment eliminates internal forging stresses and yields a refined ferrite-pearlite grain structure. This process guarantees low hardness levels across all fitting sections, fully qualifying the components for demanding sour gas and oil processing environments across the Gulf region.

Precision Machining & Export Packaging

As an established MSS SP-97 ASTM A105N branch outlet manufacturer, Haihao Group applied strict quality control measures to protect component geometry prior to maritime shipment:

Precision CNC Contour Machining: Branch outlet saddles were precision-turned to match run pipe outer diameters ranging from 4″ up to 30″, ensuring zero-gap fit-up during site welding.

Bevel & Thread Inspection: Beveled ends (BW / BLE) and NPT threads were gauged for angle tolerances, thread pitch accuracy, and defect-free sealing surfaces.

Surface Protection & Traceability: Carbon steel items were coated with anti-corrosion varnish, while stainless steel Class 6000 plugs received protective thread covers. Complete EN 10204 3.1 Mill Test Certificates were provided for all heat lots.

Partnering with a reliable MSS SP-97 ASTM A105N branch outlet manufacturer ensures seamless project execution and certified safety for high-pressure pipeline loops.
