300155 - Miller PWHT Insulation Blanket for 36-Inch Pipe

Reliable Heat Retention for 36-Inch Pipe Welds

When you are out in the field handling a Post Weld Heat Treatment (PWHT) job on a 36-inch pipe, you need insulation that fits right the first time. The Miller 300155 Insulation Blanket is cut specifically for this task. No more struggling with rolls of bulk fiber or trying to piece together scraps to cover the circumference. This blanket comes at 24 inches wide and 126 inches long, giving you a clean wrap with enough overlap to ensure the heat stays where it belongs—in the pipe.

For welders and heat treaters using induction systems like the Miller ProHeat, this blanket is your first line of defense. You wrap it around the weld zone before applying your coils. It protects your expensive heating cables from the direct heat of the steel, preventing burn-throughs and equipment failure. More importantly, it helps you hit your target temperature faster and hold it steady during the soak cycle, which is critical for passing inspection and ensuring the integrity of the weld.

Whether you are preheating to drive out moisture or performing a full stress relief cycle after welding heavy wall pipe, this blanket makes the setup process smoother. It is durable enough to handle the rigors of the job site and designed to work seamlessly with your induction setup. Don't let poor insulation compromise your heat chart; use the blanket sized for the job.
