SAEP-347 is Saudi Aramco's Engineering Procedure that governs the procurement of bulk piping materials from approved stockists. Approval under SAEP-347 Annex 4 means Gulf Union Ozone is registered in the Saudi Aramco approved stockist list for 59 specific Annex 4 material numbers — covering industrial valves, pipe fittings, flanges, and metallic pipes.
Contractors purchasing SAEP-347 Annex 4 materials from Gulf Union Ozone can do so directly without requiring additional supplier qualification steps — our Annex 4 registration satisfies Saudi Aramco's pre-qualification requirement for these material numbers.

Our document management system ensures that each batch of material in our Jeddah warehouse is matched to its corresponding MTC before dispatch.
Our 10-year document archive allows retrieval of any MTC by PO number or heat number for Aramco audit purposes. Procurement teams can request a specific historical MTC by email and receive it within one business day.
Gulf Union Ozone operates a documented quality control framework built on the Plan–Do–Check–Act (PDCA) cycle. Every operational activity — from supplier selection through to final dispatch — is governed by documented procedures that are subject to regular internal review. All materials are procured exclusively from approved mills with active ISO 9001:2015 certification, and mill certification copies are retained in our document management system.
Our QMS scope covers procurement of industrial valves, pipe fittings, flanges, and metallic pipes from approved mills; incoming material inspection and verification against EN 10204 3.1 material test certificates; segregated warehousing to prevent material mix-up; order processing and documentation control; and outbound shipment inspection to confirm material numbers and quantities match purchase orders before dispatch.
Corrective and Preventive Action (CAPA) procedures are activated whenever an inspection non-conformance, customer complaint, or internal audit finding is raised. Root cause analysis is completed within 5 business days and corrective actions are tracked to closure in our QMS document control system.
Suppliers are evaluated and maintained on an approved supplier list based on ISO certification status, MTC compliance, and delivery performance. Only mills and distributors on our approved list may supply pressure-retaining materials.
Every incoming shipment is verified against its MTC: material grade, heat number, dimensional compliance with ASME B16.5 / B16.9 / B36.10M, and quantity. Non-conforming material is quarantined with a hold tag and returned to supplier.
Internal quality reviews are conducted quarterly across all procurement and dispatch processes. All non-conformances identified in reviews are actioned within agreed timescales under our corrective action procedure. Mill supplier quality performance is evaluated annually against MTC compliance and delivery records.
Send your supplier qualification form and we'll return it completed with our CR details, SAEP-347 approval status, mill ISO 9001:2015 certificate copies, and EN 10204 3.1 sample MTCs within 1 business day.
