What is the difference between API 608 and API 607?
API 607 is a standard issued by the American Petroleum Institute (API) that specifies the performance requirements and test methods for ball valves and plug valves under fire conditions. API 607 is commonly used to assess and verify the reliability and safety of valves in fire incidents.
API 608 is a standard developed by the American Petroleum Institute (API) for metal ball valves. This standard aims to provide clear specifications and guidance for the design, manufacture, testing, and operation of industrial metal ball valves, ensuring their performance and reliability in a variety of applications.
| Comparison Aspect | API 607 | API 608 |
|---|---|---|
| Standard Nature | Fire Testing Standard for Valves | Design & Manufacturing Standard for Metal Ball Valves |
| Primary Purpose | Verify valve sealing & integrity during fire | Specify design, materials & requirements for industrial ball valves |
| Applicable Valves | Soft-seated ball valves, plug valves, butterfly valves | Metal ball valves with flanged, threaded, or welded ends |
| Key Requirement | ≤ Specified leakage rate after 30-min fire test | Structural strength, material properties, pressure-temperature rating |
| Testing Focus | External fire exposure, leakage detection, operability | Shell strength test, seat seal test, operating torque test |
| Typical Application | High-risk fire zones (e.g., oil/gas platforms, chemical plants) | General industrial piping (oil, gas, chemical) |
