2026-04-27
1000 MW Ultra-Supercritical Unit Main Steam Pipeline (540°C High Temperature + Long-Distance Thermal Expansion)
Operating Conditions: DN800, 540°C/25 MPa, Pipe Length 380 m, Thermal Expansion 420 mm, Significant Vibration (8.3 mm/s).
Solution: Combined axial and lateral expansion joints (316H) with damping devices.
Results: Vibration reduced to 1.2 mm/s (Class A), stress reduced by 65%, and no fatigue cracks observed after 6 years of operation.
Key Points: Use 316H/321 for high-temperature applications to prevent creep cracking in standard 304; incorporate damping for vibration-prone conditions.
