ASTM A403 WP316L MSS SP-95 Swage Nipples & Forged Fittings for UAE Oil & Gas

Haihao Group has finished packing and dispatched a mixed batch of piping fittings for a UAE EPC client, combining stainless steel swage nipples, socket weld branch outlets and galvanized carbon steel threaded fittings for on-site high-pressure tie-in and reduction connections. This order mixes multiple material grades and connection styles, a common requirement for oil and gas process lines where different corrosion and pressure conditions run side by side.

The core stainless steel scope features ASTM A403 WP316L MSS SP-95 swage nipples, supplied in both concentric and eccentric configurations with varied schedule wall thicknesses including S40S, S80S and S160. These swage nipples serve as compact reducers for small-bore branch lines, preferred by UAE engineering teams for tight-layout skid piping where standard butt weld reducers cannot fit. Matching socket weld elbows, 45° and 90°, plus socket weld branch outlets, are produced from ASTM A182 F316L to ASME B16.11 and MSS SP-97, rated 3000LB for corrosive process media.

Alongside the stainless package, we delivered carbon steel forged fittings built from ASTM A105 and A105N. A subset of these branch outlets is designated for sour service, with wall schedules ranging from S40 up to XXS, designed for robust hydrocarbon lines. The order also includes galvanized threaded elbows and couplings, all ASME B16.11 forged type, for auxiliary piping circuits where basic rust protection is required without heavy coating. A small set of 6000LB socket weld tees, couplings and elbows complements the high-pressure carbon steel assembly.

What makes this shipment practical for the UAE site is the unified inspection traceability across dissimilar materials. Stainless steel components go through PMI verification to confirm low-carbon 316L chemistry, while sour service A105 items are checked against client sour service requirements. Galvanized threaded pieces receive zinc coating inspection after forging and machining to avoid thread damage. Every heat lot is isolated, with MTRs grouped separately for stainless and carbon steel items so the site QA team can review documents without sorting through mixed records.

Many regional contractors in the UAE prefer to consolidate these small-bore forged fittings and swage nipples from one supplier, rather than sourcing stainless and carbon items separately. This reduces the risk of mismatched dimensions, marking standards and document formats. We can support combined packages of ASTM A403 WP316L MSS SP-95 swage nipples, socket weld fittings, threaded galvanized items and sour-service branch outlets against your P&ID or component list.

If you are sourcing compact reducing fittings and forged branch connections for UAE oil, gas or process skid projects, share your schedule, pressure class and material requirements. We can quote mixed-material packages with full material traceability and third-party inspection options.
