Al Khobar is the commercial and logistics hub for the Eastern Province's petrochemical and oil-sector supply chains, directly serving facilities in SABIC's Dhahran complex and MARAFIQ's Eastern Province utilities. The Dammam Second Industrial City, adjacent to Al Khobar, generates consistent demand for ASME B16.5 flanges in Class 150 through 2500 for process piping, utilities, and offshore support infrastructure. SWCC desalination plants along the Eastern coastline require large-bore ASME B16.47 flanges and raised-face configurations for seawater and feedwater service. SABIC Dhahran facilities specify weld neck flanges in A182 F316L for corrosive process streams.
Gulf Union Ozone holds all 15 SAEP-347 Annex 4 flange material numbers in Jeddah — covering the full range of types, pressure classes, and facing configurations required by Eastern Province operators. Our documentation package is pre-formatted for SABIC, Saudi Aramco, and MARAFIQ vendor portal submission, eliminating the additional preparation time that delays material acceptance at Eastern Province sites.
Eastern Province operators — from MARAFIQ's utility networks to SABIC's Dhahran process plants — specify SAEP-347 compatible flanges with EN 10204 3.1 documentation for all piping assemblies. Gulf Union Ozone maintains the complete set of 15 SAEP-347 Annex 4 flange material numbers in permanent stock, covering all facing types, pressure classes, and bore sizes required for Al Khobar area projects.
