Continuing from yesterday’s touchpoint on API SPEC 20A standard, the 6D from the American Petroleum Institute; provides specifications for pipeline valves and covers the design, manufacture, testing, and documentation for pipeline ball, check, gate, and plug valves for pressure ratings up to ASME class 2500.
The standard specifies configurations for the following types of valves:
• Gate valves
• Lubricated and non-lubricated plug valves
• Ball valves
• Check valves
• Full-opening valves
• Reduced-opening valves
• The valve ends may be flanged or welding. If fluid can become trapped in the body cavity, then valves for both gas and liquid service must have a pressure relief. Actuators may be electric, hydraulic, or pneumatic.
API 6D specifies the following tests:
• Hydrostatic shell test
• Stem backseat test
• Hydrostatic seat test
The standard ensures consistency and quality in the production of these valves, promoting safety, reliability, and performance in critical applications such as oil and gas transmission. Adherence to it helps facilitate interoperability and compliance with industry standards.
Its a short one because I’m also still learning myself, let’s get back to work and hope no Monday blues today.
