  • Alloy Steel: High-temperature stability for steam.

Dimensional Rigor

Every flange is machined with micron-level tolerance to ensure rapid installation and zero-leak interfaces.

  • Micron Tolerance: ±0.1mm surface flatting.
  • ASME B16.5: Fully compatible with global piping.
  • Perfect Alignment: Zero-stress bolting sequence.

Quality Certification

Full traceability from raw ingot to final inspection ensures peace of mind for critical infrastructure projects.

  • MTR Reports: Full Material Test Reports provided.
  • UT Testing: Ultrasonic testing for internal flaws.
  • ISO 9001: Strict quality management systems.
