Valves play vital roles in oil storage terminals and pipeline transportation systems with these key applications:
Storage Tank Farms
◆ Floating roof tank drain valves with emergency shut-off
◆ Breather valves for pressure/vacuum relief (API 2000 standard)
◆ Tank mixing circulation valves (butterfly type)
Pipeline Transfer Systems
◆ Mainline block valves (full-bore design)
◆ Pigging valves for pipeline cleaning
◆ Check valves to prevent backflow
Loading/Unloading Terminals
◆ Bottom loading arms with quick-connect valves
◆ Vapor recovery system control valves
◆ Overfill protection valves
Special Features
◆ Fire-safe designs (API 607)
◆ Low-temperature service (for LPG/LNG)
◆ Corrosion-resistant materials (for sour crude)
Key Requirements:
• Zero leakage performance
• Explosion-proof certification
• Emergency shutdown capability
• Long service life (>20 years)
These valves must meet strict API, ISO, and ASME standards to ensure safe operation in flammable and explosive environments.
