Industrial areas with high humidity or aggressive chemical atmospheres. Severely Corrosive:
A gas sweetening plant in the Empty Quarter (Rub' al Khali) operating at 120°C with 15% H₂S and 2,000 ppm chlorides will specify SAES-A-134 for all wetted 316L components. Standard 316L would pit and crack within months; SAES-A-134 lasts for decades.
Mandatory protective coatings must be selected based on environmental corrosivity. Critical inspection points include soil-to-air interfaces, pipe supports, and deck penetrations.
The standard acts as the foundational directive that mandates the use of Approved Saudi Aramco Coating Systems (APCS). It links directly to the SAES-H series for the actual selection and application formulas: Saes A 134 | PDF | Corrosion | Stainless Steel - Scribd saes-a-134
A: In sour service (H₂S present), NACE limits it to < 50 ppm at ambient temperature and < 0.05 ppm at high temperature. For non-sour, it can tolerate up to ~200 ppm at < 60°C.
Specifies types (e.g., FBE, 3LPE, 3LPP) for different operating temperatures.
To ensure ongoing compliance, SAES-A-134 requires a comprehensive inspection and monitoring program: Industrial areas with high humidity or aggressive chemical
Coatings must be designed to withstand cathodic disbondment.
SAES-A-134: Comprehensive Guide to Saudi Aramco's External Corrosion Protection Requirements
Saudi Aramco’s standards often reflect or exceed national and international regulations. Compliance with SAES-A-134 helps demonstrate due diligence and adherence to legal requirements. Mandatory protective coatings must be selected based on
. This table categorizes geographic and industrial areas based on their potential for aggressive corrosion. Classifications typically include: Highly Corrosive:
While the standard itself is a document, it often specifies the use of various "pieces" or components such as: Protective Coatings : It mandates specific coating systems, often referencing SAES-H-001 SAES-H-002 for material selection [17, 19]. Removable Insulation Plugs
