300071 - Miller ProHeat Air-Cooled Induction Blanket 9x85 for 24-inch Pipe

Efficient Preheating with Miller ProHeat Air-Cooled Induction Blankets

The Miller ProHeat Air-Cooled Induction Blanket (Part #300071) represents a significant advancement in industrial preheating technology. Designed specifically for use with Miller's ProHeat 35 induction heating systems, this accessory provides a highly efficient method for bringing base materials up to temperature before welding. The blanket measures 9 inches in width and 85 inches in length, specifically engineered to wrap around 24-inch diameter pipes. By utilizing electromagnetic induction, the blanket generates heat directly within the workpiece, achieving an operating efficiency of over 90 percent. This direct transfer of energy ensures uniform heating and reduces energy waste compared to traditional resistance or open-flame heating methods.

One of the primary technical advantages of this model is its air-cooled design. Unlike liquid-cooled cables and blankets that require complex chiller hookups and coolant maintenance, this air-cooled blanket relies on passive or forced air dissipation (depending on the rig setup) and the natural thermal properties of the materials to maintain safe operating temperatures for the coil itself, while heating the work up to 400 degrees Fahrenheit (204 degrees Celsius). This temperature range is ideal for driving out moisture and achieving the necessary preheat for hydrogen-induced cracking prevention in mild steels and low-alloy steels commonly found in pipeline and structural applications.

Durability in harsh industrial environments is critical. To address this, Miller includes a replaceable Kevlar sleeve with the blanket. Kevlar provides exceptional resistance to cuts, abrasions, and tears, protecting the internal induction coils from damage during handling and installation on rough pipe surfaces. This protective layer extends the service life of the blanket and ensures consistent performance in sectors such as shipbuilding, pressure vessel fabrication, and refinery maintenance. The flexibility of the blanket allows it to conform tightly to the pipe surface, ensuring optimal magnetic coupling and heating speed.

This product is an essential component for operations prioritizing speed, consistency, and safety. By eliminating open flames and reducing the setup time associated with water-cooled systems, the Miller 300071 induction blanket streamlines the preheating process. It is backed by Miller's True Blue warranty for 3 months, guaranteeing quality and reliability for your critical welding projects.
