PlywoodFactory-built PR2 validation rig for full-size API 6A gate valves Performs hydrostatic strength gas seat leakage
【Product Description】
The HJVTE series is a purpose-built, skid-mounted test facility designed to execute the complete PR2 validation sequence defined in API 6A Annex F.1.13. The unit simultaneously generates high-pressure water (up to 1 750 bar), high-pressure nitrogen (up to 1 500 bar) and programmable cryothermal cycles (–46 °C ➔ 121 °C) while continuously logging stem torque, pressure drop and leakage rate. A dual-circuit safety architecture (electronic PID + mechanical relief) guarantees compliance with PED Category IV and ASME VIII UG-136. All data are exported in .csv and encrypted .pdf formats for direct upload to ERP or third-party certification bodies.
【Applicable International Standards】
· API 6A:2021 Annex F.1.13 – PR2 Performance Validation
· ISO 10423:2021 – Petroleum and natural gas industries – Wellhead and tree equipment
· ASME VIII Div.1 UG-136 – Pressure relief devices
· PED 2014/68/EU – Category IV Module H/H1
· IEC 61010-1:2010 – Safety requirements for electrical equipment
· ASTM D1599 – Short-time hydraulic failure test
· NACE MR0175/ISO 15156 – Sour-service material compatibility
【Applications】
PR2 qualification of new API 6A gate, check, choke and ball valves; factory acceptance testing (FAT); re-certification after field service; R&D failure-mode investigation; third-party witness testing (SGS, DNV, BV).
