195477 - Miller 195477 PWHT Insulation Blanket 5-Inch Pipe

Optimized Thermal Insulation for Induction Heating

The Miller 195477 Insulation Blanket is a specialized accessory designed for Post Weld Heat Treatment (PWHT) and preheating applications using induction heating systems. Engineered specifically for 5-inch diameter pipes, this blanket measures 12 inches by 26 inches, providing the precise coverage needed to maintain thermal uniformity across the heat-affected zone. Proper insulation is critical in induction heating not only to retain heat within the workpiece—thereby improving energy efficiency—but also to protect the induction cables (coils) from the extreme surface temperatures of the pipe.

Unlike bulk ceramic wool which can be messy and difficult to reuse, this sewn blanket features a durable construction that withstands the rigors of industrial environments. It is designed to be wrapped around the pipe prior to coil installation, creating a thermal barrier that ensures the induction system operates within its optimal parameters. This is particularly important for code-quality work where maintaining specific ramp rates and soak temperatures is mandatory. The blanket helps minimize heat loss to the atmosphere, ensuring that the energy delivered by the power source is effectively utilized for stress relieving or hydrogen bake-out.

This product is an essential component for operators using Miller ProHeat systems or similar induction heating equipment. Its pre-cut dimensions eliminate the waste and labor associated with cutting bulk rolls, streamlining the setup process for 5-inch piping systems. Whether used in petrochemical refineries, power generation plant maintenance, or structural fabrication, the Miller 195477 ensures reliable thermal control and equipment protection.
