API 6A RTJ A694 Gr. 60 PSL3 blind flange
Client’s Stringent Quality Requirements
Low Sulfur Content (S ≤ 0.01%)
The sulfur content in the material was strictly controlled to ensure superior resistance to corrosion and mechanical integrity under extreme operating conditions.
Comprehensive Ultrasonic Testing (UT)
Before Machining: UT inspection was performed on raw materials to detect any internal defects that could compromise the flange’s structural integrity.
Post-Machining: Final UT inspection ensured that the finished flanges were free from cracks, voids, or other imperfections, meeting the client’s strict quality standards.
Carbon Equivalent (CE ≤ 0.43)
The maximum carbon equivalent was carefully monitored and controlled to ensure weldability and minimize the risk of cracking during fabrication or operation.
Low-Temperature Charpy Impact at -46°C
The flanges were rigorously tested to demonstrate excellent toughness and impact resistance at -46°C, ensuring reliable performance in low-temperature applications.
