Frequently Asked Questions - API 6A Training

API Specification 6A covers the requirements for wellhead and Christmas tree equipment used in oil and gas drilling and production operations. It governs the design, manufacture, and testing of equipment including casing heads, tubing heads, tubing hangers, gate valves, choke valves, and associated components. Key framework elements include Product Specification Levels (PSL 1-4), Performance Requirement Levels (PRL), material classes (AA through HH), temperature ratings, pressure ratings (2,000 to 20,000 psi), NDE requirements, and functional testing criteria. Compliance with API 6A is typically required for equipment carrying the API monogram.

PSL (Product Specification Level) in API 6A defines the level of quality system, documentation, testing, and inspection requirements applied during the manufacture of equipment. PSL 1 is the minimum standard, while PSL 4 is the most stringent - with increasing requirements for material traceability, NDE, testing, and quality system documentation. PRL (Performance Requirement Level), by contrast, defines the performance testing requirements for equipment such as valves and chokes - covering test conditions, cycles, and acceptance criteria that the equipment must satisfy to demonstrate fitness for a specific operational environment. This course covers both frameworks in detail with selection guidance and worked examples.

API 6A requires various non-destructive examination (NDE) methods depending on the PSL level and the type of component. Common NDE methods include Magnetic Particle Testing (MT) for surface and near-surface defects in ferromagnetic materials, Liquid Penetrant Testing (PT) for non-ferromagnetic surfaces, Ultrasonic Testing (UT) for volumetric examination of forgings and pressure-containing welds, and Radiographic Testing (RT) for castings and weld joints. PSL 4 requirements are the most comprehensive, requiring all of the above methods with additional personnel qualification and documentation requirements. This course covers the NDE requirements for each PSL level and how to review and accept NDE reports from your suppliers.

Yes. Petreltech offers in-house delivery of this API 6A training for corporate clients - including wellhead equipment manufacturers, oil and gas operators, EPC contractors, and inspection companies.
