Dammam port and industrial city contractors procuring flanges for Saudi Aramco Eastern Province piping projects require SAEP-347 Annex 4 compliant ASME B16.5 flanges with full EN 10204 3.1 documentation. Gulf Union Ozone stocks weld-neck, slip-on, blind, socket-weld, and lap-joint flanges in ASTM A105 carbon steel and ASTM A182 F304, F316, F11, and F22 alloy grades. Pressure classes from Class 150 through Class 2500 are maintained for all flange types. Face finishes include raised-face (RF) with 125 to 250 µin Ra serrated finish, and ring-type joint (RTJ) groove per ASME B16.5. Delivery to Dammam is 48 to 72 hours from our Jeddah warehouse for all standard sizes. Large-diameter flanges to ASME B16.47 NPS 26 through NPS 60 are available on 1 to 2 week sourcing lead time with EN 10204 3.1 certificates.

ASME B16.5 compliance is a mandatory procurement requirement for all flanged connections in Saudi Aramco Eastern Province process piping governed by SAEP-347. Gulf Union Ozone's flange lots are supplied with dimensional inspection reports confirming all critical dimensions against ASME B16.5 Table 1 and Table 2 per pressure class. Material traceability runs from mill heat number through the EN 10204 3.1 MTC to the final stamped identification mark on each flange. Saudi Aramco goods receipt at Dammam, Dhahran, and Ras Tanura requires: EN 10204 3.1 certificate, dimensional inspection record, hydrostatic test certificate, and Certificate of Conformance to the specified ASME standard. Gulf Union Ozone pre-assembles this documentation package per purchase order line item to prevent delays at Saudi Aramco goods receiving inspection.

RTJ flanges for high-pressure Dammam piping — including the Abqaiq-Yanbu pipeline and Eastern Province NGL transport lines — require Class 900 through Class 2500 weld-neck flanges with accurately machined ring grooves. Gulf Union Ozone stocks RTJ weld-neck flanges in ASTM A105 Class 900 through 2500 and ASTM A182 F316 for corrosive service Class 900 through 1500. All RTJ groove dimensions are inspected per API 6A ring groove tolerances: groove width, depth, and angle are verified and documented. Matching octagonal and oval ring gaskets in soft iron, low-carbon steel, and stainless steel are stocked across ring numbers R11 through R99. RTJ flange and ring gasket sets are available as kits, simplifying Eastern Province procurement and reducing the risk of mismatched ring groove and gasket combinations at Dammam project sites.
