Yanbu Industrial City is Saudi Arabia's western industrial hub, hosting ARAMCO Yanbu Refinery (one of the Kingdom's largest refineries), YACCO (Yanbu Aramco Sinopec Refining Company), and a dense cluster of petrochemical and plastics producers. Yanbu's location on the Red Sea also makes it a key export hub for processed hydrocarbons.
Gulf Union Ozone stocks weld neck, blind, slip-on, socket weld, and threaded flanges — all in SAEP-347 compatible configurations with EN 10204 3.1 MTCs.
All flanges meet ASME B16.5, ASME B16.47, ASME B16.36 and Saudi Aramco SAEP-347 Annex 4 requirements.
Body materials: ASTM A105N, ASTM A182 F304, F316, F316L, F321. Size range: ½" to 60" NPS, Class 150 through 2500.
Gulf Union Ozone stocks all 12 SAEP-347 Annex 4 flange material numbers (FL-001 to FL-012) in our Jeddah warehouse — weld neck, slip-on, blind, socket-weld, and threaded flanges in ASTM A105N for carbon-steel service and ASTM A182 F316L for stainless applications. Pressure classes range from 150 to 2500. Dimensional standards are ASME B16.5 covering NPS ½" to 24" and ASME B16.47 Series A/B covering NPS 26" to 60". Facing types include raised face (RF) as standard, ring-type joint (RTJ) for Class 600 and above, and flat face (FF) for Class 150 cast-iron connections. All items ship with EN 10204 3.1 MTCs carrying heat-number traceability and comply with NACE MR0175 for sour-service duty. Every order also includes ASME dimensional certificates and ISO 9001:2015 quality records. Delivery to Yanbu Industrial City is 72 hours from our Jeddah warehouse, serving YASREF, Saudi Aramco Yanbu refinery, and MARAFIQ Yanbu project sites.
Emergency orders can be expedited via dedicated road freight.
All flanges supplied with EN 10204 3.1 MTCs, Certificates of Conformance, and ISO 9001:2015 certification — formatted for ARAMCO Yanbu Refinery, YACCO, YANPET, Royal Commission for Jubail & Yanbu contractors vendor portal submission requirements.
45% Saudi-owned LLC (CR 4030570569). Full IKTVA compliance qualifying as local content supplier for Aramco, SABIC, and RCJY procurement.
Every flange 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 B16.5 flanges in Class 150 through 2500 — weld neck, blind, slip-on, socket weld, and threaded configurations — in ASTM A105N carbon steel and A182 F304/F316 stainless steel. All 15 SAEP-347 Annex 4 flange material numbers are held in our Jeddah warehouse.
Yanbu Refinery and SABIC Yanbu petrochemical plants require ASME B16.5 flanges in ASTM A105 carbon steel, ASTM A182 F316 stainless, and ASTM A182 F11/F22 chrome-moly alloys for high-temperature service. Gulf Union Ozone stocks weld-neck, slip-on, blind, socket-weld, and lap-joint flange types in all ASME B16.5 pressure classes from Class 150 through Class 2500. Raised-face and ring-type joint face finishes are available across all pressure classes. Large-diameter flanges to ASME B16.47 Series A (MSS SP-44) and Series B (API 605) are sourceable in 1 to 2 week lead time. Delivery to Yanbu from our Jeddah warehouse is same-day or next-day, making Gulf Union Ozone the fastest SAEP-347 flange supplier for Yanbu shutdowns and emergency maintenance requirements on the Red Sea industrial coast.
Ring Type Joint (RTJ) facing is mandatory for ASME Class 900 and above under ASME B16.5, and is commonly required by Saudi Aramco piping specs for high-pressure hydrocarbon and high-temperature service. We stock both RTJ and raised face (RF) flanges in all pressure classes.
Saudi Aramco SAEP-347 mandates that all flanges at Yanbu Refinery and pipeline installations carry EN 10204 3.1 Mill Test Certificates signed by the manufacturer's authorised inspector — not the third-party inspection agency, and not a 2.2 or 2.3 certificate. Gulf Union Ozone sources exclusively from certified mills producing Type 3.1 certificates compliant with EN 10204:2004. Each certificate documents: chemical composition per heat, mechanical properties (yield strength, tensile strength, elongation, Charpy impact at specified test temperature), heat treatment condition, and NDE results where applicable. The dimensional inspection record verifies all critical dimensions against the relevant ASME B16.5 or B16.47 table. This pre-assembled documentation package is designed for direct submission to Saudi Aramco goods receipt at Yanbu, reducing inspection delays and preventing documentation-related rejection.
Yes. We supply ASME B16.47 Series A (MSS SP-44) and Series B (API 605) large-bore flanges in sizes 26" through 60" NPS. These are used in pipeline and vessel nozzle applications and are supplied with EN 10204 3.1 MTCs and ASME B16.47 dimensional compliance certificates.
RTJ flanges at Yanbu are concentrated in the refinery's vacuum residue and high-pressure hydrogen service piping where Class 900 and Class 1500 pressure ratings demand leak-proof metal-to-metal sealing. Gulf Union Ozone stocks ASTM A105 RTJ weld-neck flanges in Class 900 and Class 1500, and ASTM A182 F316 RTJ flanges in Class 900 for hydrogen and high-purity service. Ring groove dimensions are machined to API 6A tolerances and individually inspected. Complementary octagonal ring gaskets in soft iron (for Class 900) and carbon steel (for Class 1500) are stocked across ring numbers R23 through R57 for common Yanbu piping sizes. RTJ flange and gasket sets for Yanbu Refinery's hydrocracker and hydrogen manifold systems can be supplied within same-day or next-day delivery lead time, supporting fast turnaround on Yanbu shutdown and emergency maintenance programmes.
Every flange order includes EN 10204 Type 3.1 MTCs with full chemical composition and mechanical test results traceable to the original mill heat number. Certificates of Conformance confirming ASME B16.5 dimensional compliance are issued for each shipment. Type 3.2 (third-party witnessed) is available on request.
