The 250,000-ton crude oil import terminal and associated pipeline project at Dongying Port is a key energy initiative in Shandong Province. As the critical link between the wharf and storage tank farm, the pipeline system (Dongying Port Terminal Station) demands exceptionally high reliability and safety standards for its valves. As a core supplier of fluid control equipment, our company provided 2 DN800 CLASS300 large-diameter V-port ball valves for this project, which have now undergone rigorous factory quality inspections.

Technical Highlights

• High-Standard Design:
• Size: DN800 (32 inches)
• Pressure Rating: CLASS300 (PN50)
• Compliance: API 6D + ISO 17292
• Core Technological Breakthroughs:
• Bidirectional metal hard-seal design for zero leakage
• ASTM-grade valve body for coastal corrosion resistance
• Hydraulic actuator for rapid response
• Quality Verification Process

On May 8–9, 2025, the two valves underwent stringent factory tests, including:

Test Item                  Requirement                          Result

Shell Hydrostatic Test 78 Bar strength test, 5 min pressure hold          Passed

Valve Seat Leak Test 4.5 Bar leakage test, <58,718.255 mL/min per ANSI  Passed

All test results met design specifications and project requirements.

Project Progress

• Completed:
• Design review
• Manufacturing quality control
• Factory pressure & leakage tests
• Next Steps:
• Opening/closing time test
• Packaging & Shipment
