Low carbon content enhances welding performance and reduces intergranular corrosion risk, providing excellent corrosion resistance and mechanical stability.
- Complete forging and processing solutions with comprehensive in-house capabilities
- Full production cycle from forging blank preparation to final machining
- 500 tons of flange blanks in stock for rapid order fulfillment
- Capability to handle both standard and non-standard orders
- Certified to PED, ISO, and NORSOK M-650 standards
Our flanges undergo precision free forging for optimal structural density and mechanical properties. Post-forging solid solution annealing eliminates stress while enhancing corrosion resistance. Multiple machining processes ensure precise dimensions and surface finish for reliable long-term sealing performance in demanding pipeline systems.
- 100% dimensional and visual inspection
- Traceability coding for each product
- Optional testing including PMI material analysis, ultrasonic flaw detection (UT), and penetrant testing (PT)
- Third-party witness inspection available
