194998 - Miller ProHeat Insulation Blanket for 28-Inch Pipe

High-Efficiency Thermal Insulation for Induction Heating

The Miller 194998 Insulation Blanket is a specialized accessory designed for use with induction heating systems, such as the Miller ProHeat 35. Engineered specifically for 28-inch diameter pipes, this blanket measures 24 inches in width and 98 inches in length, providing optimal coverage for Post Weld Heat Treatment (PWHT) and preheating applications. In the context of industrial welding, maintaining precise temperature control is critical for ensuring the metallurgical integrity of the weldment. This insulation blanket serves as a vital thermal barrier, significantly reducing heat loss to the surrounding environment and ensuring that energy is efficiently directed into the workpiece.

Beyond thermal efficiency, the blanket plays a crucial protective role. It is placed between the workpiece and the liquid-cooled induction heating cables (coils). This arrangement protects the cables from the extreme conductive heat of the pipe, which can reach temperatures required for stress relief (often exceeding 1100°F or 600°C), thereby extending the lifespan of the induction equipment. The material composition is selected to withstand high temperatures while offering durability in rugged job site environments. By ensuring uniform heat distribution across the Heat Affected Zone (HAZ), the Miller 194998 helps operators meet stringent welding codes and quality standards found in petrochemical, power generation, and pipeline construction sectors.
