Every pipe fitting order ships with EN 10204 Type 3.1 Mill Test Certificates with chemical composition, mechanical test results, and inspector stamp — satisfying Saudi Aramco Goods Receipt inspection requirements under SAEP-347.
We stock ASME B16.9 butt weld fittings (elbows 90°/45°, equal and reducing tees, concentric and eccentric reducers, caps) in schedules SCH 40, SCH 80, SCH 160, and XXS, plus ASME B16.11 socket weld and threaded fittings in Class 3000 and 6000. All 36 SAEP-347 pipe fitting material numbers are in stock.
Dammam Eastern Province piping contractors require SAEP-347 compliant ASME B16.9 and B16.11 pipe fittings for Saudi Aramco offshore and onshore facilities maintenance and capital projects. Gulf Union Ozone stocks carbon steel ASTM A234 WPB elbows, tees, reducers, and caps in schedule 40, 80, 160, and XXS, and stainless steel ASTM A403 WP304L and WP316L in schedules 5S through 80S, across sizes half-inch through twenty-four-inch NPS. ASME B16.11 socket-weld and threaded fittings in Class 3000 and Class 6000 are stocked for small-bore applications. All fittings are accompanied by EN 10204 3.1 MTCs and ASME dimensional inspection certificates. Delivery to Dammam site or port warehouse is 48 to 72 hours from our Jeddah facility for all standard stock items; emergency orders dispatch same-day for receipts before 14:00 AST.
ASME B16.9 covers butt-weld fittings (elbows, tees, reducers) for NPS ½" to 48" — used in welded piping systems. ASME B16.11 covers forged socket weld and threaded fittings typically in Class 3000 or 6000 for small-bore high-pressure piping (NPS ≤4"). Butt weld for large-bore and high-cycle systems; socket weld and threaded for instrument tie-ins and small lines.
Butt-weld ASME B16.9 fittings are the primary joining method for Saudi Aramco Eastern Province process piping in sizes above two-inch NPS, where full radiographic weld inspection of butt-weld joints meets ASME B31.3 code requirements. Socket-weld ASME B16.11 fittings are used for small-bore utility, instrument, and drain connections where radiographic inspection is not required. Gulf Union Ozone maintains both product lines for Dammam customers: long-radius 90-degree and 45-degree elbows, equal and reducing tees, concentric and eccentric reducers, and caps in butt-weld configurations; and elbows, tees, couplings, half-couplings, and bossets in socket-weld Class 3000 and 6000. Wall thickness schedule, material grade, and heat number are verified in the dimensional inspection report included with every fitting lot delivery to Dammam projects.
Yes. We stock heavy-wall schedule fittings (SCH 80, 160, XXS) in ASTM A234 WPB carbon steel for high-pressure, high-temperature hydrocarbon piping — common in refinery and gas plant applications. All heavy-wall fittings are supplied with EN 10204 3.1 MTCs and ASME B16.9 dimensional compliance reports.
NACE MR0175 compliant pipe fittings for Dammam sour service piping — including production flowlines, gas gathering headers, and produced water injection systems — require controlled hardness and special heat treatment to prevent sulphide stress cracking. Gulf Union Ozone supplies ASTM A234 WPB ASME B16.9 fittings with Rockwell C hardness certificates confirming 22 HRC maximum on body, weld deposit, and heat-affected zone. ASTM A403 WP316L stainless fittings for corrosive sour service include low-carbon content verification (0.03% max) in the EN 10204 3.1 MTC. The complete NACE MR0175 documentation package for Dammam project sites includes: Mill Test Certificate, Hardness Certificate, Dimensional Inspection Certificate, Certificate of Conformance to ASME B16.9 or B16.11, and Heat Treatment Certificate where applicable.
Every order includes EN 10204 3.1 MTCs (traceable to mill heat number), Certificates of Conformance confirming ASME B16.9 or B16.11 dimensional standards, and ISO 9001:2015 quality records. SAEP-347 compatibility documentation is available on request for orders that include Annex 4 material numbers.
