Carbon Steel Pipe Supplier Al Khobar, Saudi Arabia

Gulf Union Ozone supplies carbon steel pipe to Al Khobar and Dhahran-area contractors from our Jeddah headquarters warehouse, with 24-to-48-hour delivery to the Eastern Province. ASTM A106 Grade B seamless pipe — the most common SAEP-347 Annex 4 process piping material — is held in Schedule 40, 80, 160, and XXS from ½" NB to 24" NB. API 5L Grade B, X42, X52, X60, and X65 for oil and gas transmission projects, and ASTM A53 Grade B for utility service, are also stocked. Saudi Aramco Dhahran engineering office contractors, King Salman Energy Park (SPARK) industrial tenants 60 km south of Khobar, and Bahrain-facing EPC teams who source from the Khobar side of the King Fahd Causeway are all served with full EN 10204 3.1 MTC documentation traceable to the original mill heat number and formatted for Saudi Aramco Goods Receipt inspection.

Saudi Aramco Dhahran's engineering approval process for procurement orders — the Goods Receipt (GR) inspection at Aramco's Eastern Province receiving facilities — requires carbon steel pipe to carry SAEP-347 Annex 4 material numbers with EN 10204 3.1 Mill Test Certificates traceable to the original mill heat. The three most common Annex 4 material numbers for process piping at Dhahran and Eastern Province plants are ASTM A106 Grade B seamless (the dominant ASME B31.3 process piping specification), API 5L Grade B ERW (lower-pressure utility service), and API 5L Grade X52 or X60 PSL2 (for natural gas transmission and production gathering lines). Gulf Union Ozone holds all three in standard schedule wall thicknesses and delivers to Khobar within 24 to 48 hours, with pre-assembled GR-ready documentation packages.

SPARK industrial tenants have a specific procurement challenge not faced by Jubail-based buyers: SPARK is still a developing zone where not all operators have established local materials warehouses. EPC contractors installing process plant at SPARK frequently place emergency procurement orders for SAEP-347 Annex 4 piping materials with 24-to-48-hour lead times. The grades most frequently requested for SPARK process plant installations are ASTM A106 Grade B seamless in Schedule 80 and 160 for high-pressure process piping, API 5L Grade X52 PSL2 for intra-zone gas transmission headers, and ASTM A53 Grade B for utility steam, compressed air, and cooling water lines. Gulf Union Ozone holds all of these at our Jeddah warehouse and can dispatch to SPARK within 24 hours — including full EN 10204 3.1 MTC documentation.
