Product Introduction
The bolt heater is a specialized heating tool designed for installing and removing bolts in large equipment such as steam turbines.
Working Principle
The bolt is heated via electric heating or induction, causing it to expand and thereby reducing the required tightening torque. This enhances operational efficiency and connection reliability.
Core Functions
1) Thermal Tightening Application: Heated bolts elongate, enabling precise application of initial stress to ensure cylinder sealing integrity and accommodate long-term operational creep.
2) Temperature Differential Control: Heating flanges/bolts during startup/shutdown minimizes thermal gradients with cylinders, preventing deformation or cracking from thermal stress.
Rapid Maintenance: Uniform heating shortens disassembly/assembly time for large bolts, particularly suitable for applications like power plant turbines.
