Flexible Bolt Heaters

Product Description

In the world of industrial maintenance and shutdown operations, time is money. When you're working with massive machinery like turbines, pressure vessels, or large-diameter flanges, even something as small as a bolt can be the bottleneck that holds everything up. Enter the Flexible Bolt Heater – a compact, high-temperature heating device that helps make bolt removal and insertion faster, safer, and more precise. A flexible bolt heater is a resistance-based heating element, typically inserted into the hollow center of a stud bolt. Unlike surface heating methods, this device heats the bolt from the inside out, expanding it uniformly. Once expanded, the bolt is easier to remove, or in the case of installation, tightens naturally upon cooling to ensure optimal clamping force. This greatly minimizes mechanical stress on casings, avoids thread seizure during bolt removal, and prevents micro-fractures caused by over-tightening.
