What Documents Are Needed for API 607 Fire Testing of API 6D Ball Valves | Required Documentation and Certification Requirements
For API 6D ball valves to undergo API 607 fire resistance testing, design drawings, material certificates (EN10204 3.1), pressure rating and dimensional data, test procedures, instrument calibration certificates and type test reports must be provided. The test is usually conducted under a 650°C flame for 30 minutes, and leakage rate and sealing performance are recorded, […]
How to Pass API 607 Fire Testing with an API 6D Ball Valve Design | Fire-Safe Design Optimization and Leakage Control
Adopt metal + soft seal dual structure, after fire burn metal seal leakage ≤ 100 ml/min;Packing select graphite withstand temperature ≥ 700℃;Valve seat add spring compensation structure, ensure after thermal deformation still fit;Conduct API 607 full process fire test and cold state re-test verification. design optimization Dual Sealing Mechanism When inside pipe pressure reaches 10 […]
