What is API 607 Certification
The API 607 Standard, developed by the American Petroleum Institute (API), defines rigorous fire-testing protocols for quarter-turn valves (ball/plug valves) and valves with non-metallic seats. This certification verifies valve integrity during fire emergencies, ensuring:
- Fire resistance under extreme temperatures
- Leak-tight sealing during/after fire exposure
- Operational functionality post-fire event
Key Requirements of API 607 Testing
| Test Parameter | Specification | Certification Criteria |
|---|---|---|
| Temperature Range | 650°C–760°C (1202°F–1400°F) | 30-minute sustained exposure |
| Pressure Testing | 75%–100% rated pressure | Zero leakage demonstration |
| Cooling Method | Water quenching | Structural integrity retention |
| Operational Test | Post-fire cycling | Torque compliance |
Industries Requiring API 607 Certification
1. Oil Refineries: Emergency shutdown systems
2. Chemical Plants: Hazardous fluid control
3. LNG Facilities: Cryogenic service valves
4. Offshore Platforms: High-pressure hydrocarbon valves
API 607 vs. Related Standards
| Standard | Scope | Valve Types Covered |
|---|---|---|
| API 607 | Quarter-turn valves & non-metallic seats | Ball valves, plug valves |
| API 6FA | General fire testing for API 6A/6D valves | Gate valves, ball valves, plug valves |
| API 6FD | Check valve-specific fire resistance | Swing check valves, lift check valves |
4-Step Certification Process
1. Design Validation: Submit material specs & engineering drawings
2. Laboratory Testing: Fire simulation at accredited facilities
3. Manufacturing Audit: Quality system verification
4. Continuous Compliance: Annual audits & version updates
2023 Revision Alert: The latest edition mandates testing for hybrid sealing materials – review updates via API official portal.
