300078 - Miller ProHeat Air-Cooled Induction Blanket for 12-Inch Pipe

High-Efficiency Preheating for Industrial Piping

The Miller ProHeat Air-Cooled Induction Blanket (Stock No. 300078) is a specialized accessory engineered for the rigorous demands of industrial welding, specifically within the pipeline, shipbuilding, and refinery sectors. Designed to integrate seamlessly with Miller's ProHeat induction heating systems, this blanket provides a consistent and controlled method for preheating 12-inch diameter pipes. Unlike open-flame methods which can introduce moisture and inconsistent heating zones, induction heating induces heat directly within the base metal, ensuring a uniform temperature profile that is critical for code-quality welds.

This model features an air-cooled design, which significantly simplifies job site logistics. By eliminating the requirement for liquid cooling lines and chillers, operators can set up faster and move equipment with greater freedom. The blanket measures 10.1 inches by 47 inches, perfectly sized to wrap around standard 12-inch pipes. It is rated for preheating applications up to 400 degrees Fahrenheit, making it ideal for driving out moisture and reducing thermal shock in mild steel and alloy applications.

Durability is a key focus of the 300078 model. Industrial environments are notoriously harsh on equipment, with sharp edges and rough surfaces being commonplace. To combat this, Miller includes a replaceable Kevlar sleeve with the blanket. This sleeve provides robust protection against abrasions, cuts, and tears, ensuring the induction coil remains intact and operational for longer periods. With an operating efficiency of over 90%, this blanket delivers maximum energy transfer to the workpiece, reducing energy costs and heating time compared to traditional resistance pads or flame heating.

Key Industrial Benefits:

• Process Control: Delivers precise temperature control essential for critical structural and pressure vessel welding.
• Operational Efficiency: Air cooling reduces the equipment footprint and maintenance associated with water-cooled alternatives.
• Longevity: The Kevlar outer layer protects the investment from daily wear and tear found in shipyards and construction sites.
