Product Introduction
Steam turbine header bolts serve as the core fasteners connecting the header to the cylinder/governor valve flange. Their primary function is to compress the sealing gasket, preventing high-temperature, high-pressure steam leakage while withstanding thermal stresses from steam temperature fluctuations and pipeline vibration loads. Their reliability directly impacts the unit's thermal efficiency and operational safety, preventing issues such as equipment burns and efficiency loss caused by steam leakage.
1. Primary Functions:
1) Seal and prevent leakage.
2) Withstand alternating loads (high-temperature thermal stress, axial steam pull, pipeline vibration stress, etc.).
3) Maintain pipeline connection stability.
4) Adapt to thermal expansion and contraction of flanges during unit startup/shutdown and load adjustments through inherent strength and toughness, preserving stable preload.
2. Structural Types:
Primarily categorized as high-temperature/high-pressure bolts and medium/low-temperature/medium/low-pressure bolts based on application scenarios.
3. Common Failures:
1) Bolt loosening and seal leakage.
2) Bolt fracture.
3) Bolt corrosion and high-temperature oxidation.
4) Bolt creep deformation at elevated temperatures.
