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.

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.

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.
