API 16C Choke and Kill Systems
Compliance & Engineering Support - specialised API 16C services for choke and kill systems, helping manufacturers, EPC contractors, and drilling operators meet the highest global standards for well control equipment.
End-to-End API 16C Compliance for Choke and Kill Systems
In well control operations, choke and kill systems are critical safety barriers. At Petreltech, we provide specialised API 16C compliance services for choke and kill equipment - ensuring your systems meet stringent design, manufacturing, and testing requirements from the latest API 16C specification.
Our services cover engineering design review, quality assurance, pressure testing, and complete documentation - supporting OEMs, fabricators, and drilling contractors in delivering API 16C certified choke and kill systems with confidence.
What Is API 16C?
API 16C is the American Petroleum Institute's specification for choke and kill systems used in drilling and well intervention operations. It defines the requirements for design, materials, pressure ratings, testing, and documentation of choke manifolds, kill lines, flexible joints, and associated well control components.
Key Elements of API 16C
The specification defines critical requirements covering design, materials, pressure ratings, testing, and documentation for choke and kill system components
Design and pressure rating requirements for choke and kill equipment
Material specifications, heat traceability, and NDT requirements
Hydrostatic and functional pressure testing protocols
Welding procedures, inspection, and qualification requirements
PSL (Product Specification Level) and temperature class ratings
API monogram program requirements and marking guidelines
