194947 - Miller 194947 PWHT Insulation Blanket for 2.5 Inch Pipe

Miller 194947 Insulation Blanket for PWHT Applications

The Miller 194947 is a specialized insulation blanket designed specifically for Post-Weld Heat Treatment (PWHT) applications on 2.5-inch diameter pipes. Measuring 12 inches by 15 inches, this pre-cut blanket is an essential accessory for professionals utilizing induction heating systems, such as the Miller ProHeat 35, to perform stress relief on welded pipe joints. In the demanding field of industrial welding, maintaining precise temperature control and thermal efficiency is paramount, and high-quality insulation is the key to achieving these results.

This insulation blanket serves a dual purpose in the induction heating process. First, it acts as a thermal barrier that retains heat within the workpiece, ensuring that the target temperature for stress relief is reached efficiently and maintained for the required soak time. Without proper insulation, heat loss to the surrounding environment would be significant, leading to energy inefficiency and potential inconsistencies in the heat treatment profile. Second, and equally important, the blanket provides a protective layer between the hot workpiece and the induction heating cables (coils). By preventing direct contact, the blanket shields the liquid-cooled cables from the extreme temperatures of the pipe, thereby extending the lifespan of the equipment and preventing costly damage.

The pre-cut nature of the Miller 194947 offers a significant advantage over bulk insulation rolls. It eliminates the need for measuring and cutting on the job site, which streamlines the setup process and reduces labor time. The dimensions are optimized for 2.5-inch pipes, ensuring a proper fit without excessive overlap or gaps that could compromise thermal uniformity. Whether used in petrochemical plants, power generation facilities, or pipeline construction, this insulation blanket is a critical component for ensuring code-compliant PWHT results.
