What Is API 16A?
API 16A is the American Petroleum Institute's specification for drill-through equipment, including blowout preventers (BOPs), ram blocks, and other pressure control components. It defines the critical requirements for design, performance, material, welding, marking, and testing.
Key Elements of API 16A
The specification defines critical requirements for design, performance, material, welding, marking, and testing of drill-through equipment
Design verification of BOPs and pressure control assemblies
Material specifications, traceability, and NDT requirements
Welding procedures, inspection, and documentation
API monogram program requirements
