What is SAEP-347 and who needs to comply with it?

SAEP-347 is Saudi Aramco's Engineering Procedure governing the purchase, inspection, and documentation requirements for valves, pipe fittings, flanges, and metallic piping used in Aramco facilities. Any contractor or sub-contractor procuring these materials for Saudi Aramco projects must ensure suppliers are compliant with SAEP-347 requirements, including MTCs, CoCs, and approved material grades.

Which material grades and standards are covered in SAEP-347 Annex 4?

SAEP-347 Annex 4 covers a wide range of materials including carbon steel (ASTM A105, A234 WPB, A350 LF2), stainless steel (316L, 304), duplex stainless steel, alloy steel, and various ASME/ANSI rated fittings and flanges. Gulf Union Ozone stocks products compatible with 59 Saudi Aramco material numbers across these categories.

What documentation comes with SAEP-347 compatible materials from Gulf Union Ozone?

Every order includes full Material Test Certificates (MTCs) with chemical and mechanical properties, Certificates of Conformance (CoC), manufacturer mill certificates, ISO 9001:2015 quality system documentation, packing lists with heat and lot numbers, and inspection reports upon request. All documents are traceable back to the original mill heat.

SAEP-347 Annex 4 — All 59 Stockable Numbers

What is SAEP-347?

How Does Saudi Aramco SAEP-347 Stockist Supply Work?

SAEP-347 is a Saudi Aramco Engineering Procedure that defines the requirements for stockist suppliers who supply materials from stock — rather than direct from manufacturer.

Annex 4 of SAEP-347 contains the List of Stockable 9COMS: specific material numbers that Aramco allows to be sourced from approved stockists.

Gulf Union Ozone Trading Co. supplies products meeting the specifications of 59 material numbers listed in SAEP-347 Annex 4 — covering valves (23), pipe fittings and flanges (24), and metallic pipes (12). All products supplied with full material documentation.

9COMS, 9CAT & 9COM explained: In Saudi Aramco's Materials System (SAP), "9COMS" refers to 9000-class Commodity Materials that are stockable — the category that SAEP-347 Annex 4 defines. "9CAT" (9000 CAtalogue) refers to catalogued Aramco material numbers in the 9000 series. When procurement engineers search for "9COM supplier" or "9CAT valve Jeddah," they are looking for the same SAEP-347 Annex 4 stockable items that Gulf Union Ozone provides. Aramco material numbers in this category follow the format 6000XXXXXX (10 digits beginning with 6000).

"SAEP-347 Compatible" vs "SAEP-347 Approved Vendor": Gulf Union Ozone supplies products meeting the material specifications defined in SAEP-347 Annex 4 — grades, standards, documentation. Inclusion on Saudi Aramco's official Approved Stockist List (Annex 5 of SAEP-347) is a separate vendor qualification process managed by Saudi Aramco's Materials Supply organisation. See our full SAEP-347 guide for the complete compliance framework.

In Summary

SAEP-347 authorises Saudi Aramco contractors to source 9COM (Commodity) materials from approved stockist suppliers rather than directly from OEMs, provided three conditions are met: the material number appears in SAEP-347 Annex 4, the stockist holds an approved vendor listing, and every item is accompanied by an EN 10204 3.1 mill test certificate with unbroken heat-number traceability. This contrasts with 7COM procurement, where materials are ordered directly from the original manufacturer to a specific purchase order — a process that typically takes 6 to 12 weeks lead time. 9COM stockist supply compresses that to 2 to 4 days from a compliant Jeddah warehouse, which is critical during plant maintenance Turnaround (TA) windows where downtime losses for large process plants are widely cited in the industry at USD 1 million or more per day. Saudi Aramco introduced the 9COM commodity classification to allow verified fast-track supply without sacrificing quality or traceability. All 59 qualifying material numbers — spanning valves, pipe fittings, flanges, and metallic pipes — are defined in SAEP-347 Annex 4.

Terminology

"SAEP-347 Compatible" vs "SAEP-347 Approved Vendor" — What's the Difference?

Procurement engineers often ask whether Gulf Union Ozone is on Saudi Aramco's Approved Vendor List. Here is a precise explanation of the terminology so you can make the right procurement decision.

What "SAEP-347 Compatible" Means

Gulf Union Ozone Trading Co. stocks products that meet the material specifications defined in SAEP-347 Annex 4: the correct ASTM grade, the correct dimensional standard (ASME B16.5/B16.9/B16.11 etc.), the correct pressure class, and the required documentation — EN 10204 3.1 MTCs, Certificates of Conformance, and API test reports where applicable.

This means an Aramco contractor can procure 9COM items from Gulf Union Ozone and submit the accompanying documentation package through the Aramco Goods Receipt process — the materials meet the specification requirements of the applicable material number.

What "Approved Vendor" (ASL) Means

Saudi Aramco's Approved Supplier List (ASL) — sometimes called the Approved Vendor List or AVL — is a formal vendor qualification register managed by Saudi Aramco's Materials Supply and Supply Chain Management organisations. To appear on the ASL for stockist supply, a vendor must complete a formal qualification process including facility audits, quality system review, financial checks, and approval by Aramco's procurement authority.

Gulf Union Ozone is pursuing registration on the Aramco Ariba supplier portal as part of an ongoing commercial development initiative. Contractor procurement engineers who have sourced from Gulf Union Ozone can include our documentation package in their own Goods Receipt submissions under their vendor approvals.

Bottom line for procurement engineers: Gulf Union Ozone supplies the correct materials with the correct documentation for your SAEP-347 Goods Receipt. If your Aramco contract requires sourcing exclusively from the Aramco ASL-registered stockist list, confirm with your Aramco Materials Representative before placing an order. If your contract permits use of specification-compliant stockists with full material traceability, Gulf Union Ozone can fulfil the requirement.

Broader Industrial Scope

Beyond Saudi Aramco: Other KSA Industrial Customers We Serve

SAEP-347 compatible materials — full EN 10204 3.1 MTC traceability, ASTM/ASME material grades, ISO 9001:2015 documentation — meet the procurement standards of every major Saudi industrial authority, not only Saudi Aramco contractors. Gulf Union Ozone supplies the same specification-grade materials and documentation to SABIC affiliates and their EPC contractors, MARAFIQ (Power and Water Utility Company for Jubail and Yanbu), SWCC (Saline Water Conversion Corporation), Saudi Electricity Company (SEC) power generation and grid projects, National Water Company (NWC) municipal infrastructure, TASNEE (National Industrialisation Company) petrochemical operations, Aramco affiliates SATORP (Ras Tanura Integrated Refinery) and SADARA (Jubail Chemical Company), and international EPC contractors executing LSTK projects across the Kingdom. If your project requires mill-traceable industrial piping materials with documentation sufficient for Saudi Aramco Goods Receipt, those same materials satisfy the equivalent documentation standards of any SABIC, MARAFIQ, or SEC procurement team.

A Jeddah-based EPC subcontractor was executing a tie-in package at a hydrocarbon facility in the Eastern Province of Saudi Arabia. During the pre-turnaround material check, the site team identified a documentation shortfall: three purchase orders for ball valves, weld neck flanges, and butt weld fittings held by the original vendor were missing EN 10204 3.1 MTCs traceable to the originating mill heat number. Goods Receipt at the Aramco facility would not be posted without compliant documents.

Constraint

The plant turnaround window was 72 hours. Materials had to be delivered to the Aramco facility gate with compliant documentation within 48 hours or the tie-in package would slip to the next scheduled maintenance window — an additional 3-month delay.

Materials Supplied (SAEP-347 Annex 4)

✔ Ball valves, ASTM A216 WCB, ASME Class 150, 2″ to 6″ NPS — 18 units
✔ Weld neck flanges, ASTM A105N, ASME B16.5 Class 300, RF, 4″ to 12″ NPS — 32 units
✔ Butt weld elbows and tees, ASTM A234 WPB, ASME B16.9, Sch 40, 3″ to 8″ NPS — 47 pieces

Outcome

All 97 items were pulled from Gulf Union Ozone's Jeddah stock and dispatched within 6 hours of the WhatsApp enquiry. Original EN 10204 3.1 MTCs were retrieved from the mill archives and verified before dispatch. The complete package — materials, MTCs, Certificates of Conformance, and packing lists with heat numbers — arrived at the Aramco facility gate in 31 hours. Goods Receipt was posted by the Aramco Materials team on first inspection with no NCRs raised. The tie-in package was completed within the turnaround window.
