End-to-End API 6D Compliance Support for Pipeline and Piping Valves
In critical pipeline systems, valve performance is central to flow control, safety, and pressure integrity. At Petreltech, we provide expert API 6D pipeline valve compliance services for EPC contractors and operators-ensuring your valves meet stringent industry standards from design to delivery.
Whether it's ball, gate, check, or plug valves, our team ensures full compliance with the latest API 6D specification, offering engineering review, testing, inspection, and complete documentation support.
What Is API 6D?
API 6D is the American Petroleum Institute's specification for pipeline and piping valves. It defines the requirements for design, manufacturing, inspection, and testing of valves used in oil, gas, and petrochemical pipelines.
By meeting API 6D compliance standards, manufacturers and operators demonstrate their commitment to safe, reliable, and globally accepted pipeline valve performance and integrity.
Key Elements of API 6D
The specification covers critical technical and performance requirements for all pipeline and piping valve types
Valve types: gate, plug, ball, and check valves
Design, material, and pressure class requirements
PSL (Product Specification Levels) and temperature ratings
Pressure testing, shell and seat testing protocols
Welding and NDT requirements
Marking, traceability, and API monogram guidelines
