Corroshield® PTFE-Coated Stud Bolts ASTM A193 B7 Supplied for PTSC’s FPSO Floating Hose

Engineering Edge Vietnam (EEV) proudly supplied Corroshield® PTFE-coated stud bolts, manufactured to ASTM A193 Grade B7 standards, for PTSC’s offshore FPSO system. These fasteners were specifically used on floating hoses—critical components that remain fully exposed to sea water year-round, making corrosion resistance and long-term durability essential.

Application: Offshore Floating Hose on FPSO

Floating hoses are a key interface for crude oil transfer between FPSOs and shuttle tankers. Operating in harsh offshore environments, they are constantly exposed to saltwater, humidity, and UV radiation, which pose significant challenges for any mechanical connection. The stud bolts used in these assemblies must withstand corrosion, mechanical stress, and thermal cycling without failure.

Why Corroshield® PTFE-Coated Stud Bolts?

EEV’s stud bolts coated with Corroshield® PTFE offer a robust solution tailored for such extreme marine conditions:

• ✅ Exceptional Corrosion Resistance: The PTFE coating provides a highly resistant barrier against saltwater corrosion, extending the service life of the fasteners.
• ✅ Low Friction & Easy Maintenance: PTFE’s low friction coefficient allows for easier installation and removal, even after prolonged exposure in marine environments.
• ✅ High Mechanical Strength: Manufactured in compliance with ASTM A193 B7, these bolts maintain their structural integrity under high-pressure and high-temperature conditions.
• ✅ Long-Term Cost Efficiency: Enhanced durability reduces the frequency of maintenance or replacement, contributing to reduced operational downtime and cost savings.

Project Significance

Supplying these high-performance fasteners to PTSC, a major player in Vietnam’s oil & gas services sector, reinforces EEV’s position as a trusted manufacturer of specialized bolting solutions for the offshore and energy industries. The application on FPSO floating hoses highlights EEV’s ability to deliver reliable, fit-for-purpose products tailored for critical offshore operations.
