| Feature | Onshore (SAES-A-134 Onshore) | Offshore (SAES-A-134 Offshore) | |---------|-------------------------------|--------------------------------| | Coating | 3LPP or FBE (minimum 400 µm) | Concrete weight coating + FBE | | Trenching | Required for HDD crossings | Required in scour zones & shore approaches | | Vents/Blowdowns | Required every 20 km | Not typical (riser relief valves) | | Corrosion allowance | 3 mm (sweet) / 6 mm (sour) | 3 mm + CP system |
In conclusion, SAES-A-134 is a critical standard for the Saudi Arabian oil and gas sector, outlining the requirements for the design, fabrication, inspection, testing, and documentation of pipeline systems. The standard has had a significant impact on the industry, enhancing safety, reliability, and efficiency, while also promoting international cooperation and trade. As the industry continues to evolve, it is essential that SAES-A-134 remains a living standard, regularly updated to reflect changes in technology, industry best practices, and regulatory requirements.
The choice of an external protective coating system relies directly on the atmospheric and operational guidelines outlined in the standard. SAES-A-134 coordinates with the SAES-H series to assign pre-qualified Approved Protective Coating Systems (APCS) for various applications: Saes A 134 | PDF | Corrosion | Stainless Steel - Scribd
Future revisions are expected to incorporate and hydrogen blending compatibility (up to 10% H₂). saes-a-134
is a mandatory Saudi Aramco Engineering Standard (SAES) that defines the minimum engineering requirements for external corrosion protection across industrial infrastructure. Operating in some of the most aggressive environmental conditions in the world—characterized by high atmospheric salinity, scorching heat, and corrosive soils—Saudi Aramco relies on this document to guarantee long-term mechanical integrity, safety, and reliability.

: As detailed above, it addresses corrosion of the outer surfaces of assets, primarily through coatings and cathodic protection. | Feature | Onshore (SAES-A-134 Onshore) | Offshore
The scope of SAES-A-134 typically covers:
To be effective, coatings must be applied to a properly prepared surface. The standard sets strict requirements for surface cleanliness (e.g., Near-White Metal Blast Cleaning, NACE No. 2 / SSPC-SP 10) and profile to ensure coating adhesion. It also outlines inspection protocols, including the use of holiday detectors to find pinholes in the coating, and adhesion tests.
: In severe environments, austenitic stainless steel fasteners are restricted for certain applications like cable trays. Corrosion Under Insulation (CUI) and Fireproofing (CUF) CUI is a major risk for insulated piping. The choice of an external protective coating system
: Governed strictly by the companion standard SAES-A-133 . 2. Structural Breakdown of External Corrosion Threats
Protection against atmospheric corrosion and CUI. 4. Importance of Compliance
This technical standard dictates structural safety and asset longevity from the initial design phase through construction, maintenance, and final repairs. 1. Scope and Core Framework
Hot bends must be induction-bent and post-weld heat treated (PWHT).
Given the prevalence of sour fields (e.g., Ghawar, Khurais), SAES-A-134 includes mandatory provisions for H₂S service:
