300064 - Miller ProHeat 38-Inch Pipe Induction Blanket

High-Efficiency Preheating for 38-Inch Pipe Applications

The Miller ProHeat Air-Cooled Induction Blanket (SKU: 300064) is a specialized accessory engineered for the rigorous demands of industrial welding and fabrication. Designed specifically to fit 38-inch diameter pipes, this blanket measures 7.5 inches in width and 129 inches in length, ensuring optimal coil spacing and magnetic field coupling for uniform heating. As an integral component of the Miller ProHeat induction heating system, it provides a highly efficient method for preheating weld joints, capable of reaching temperatures up to 400 degrees Fahrenheit (204 degrees Celsius).

One of the primary technical advantages of this model is its air-cooled design. Unlike liquid-cooled alternatives that require chillers, coolant lines, and additional maintenance, this air-cooled blanket simplifies the setup process and reduces overall installation costs. It achieves an operation efficiency of over 90 percent, transferring energy directly into the workpiece with minimal loss. This efficiency makes it suitable for a wide range of wall thicknesses, from thin-walled pressure vessels to heavy-wall structural components found in refineries and power plants.

Durability is paramount in field environments such as pipeline construction and shipbuilding. To address this, the Miller 300064 comes equipped with a replaceable Kevlar sleeve. This rugged outer layer protects the internal induction coils from abrasions, cuts, and tears that can occur during handling and positioning on rough metal surfaces. The combination of high thermal performance, ease of deployment, and robust construction makes this induction blanket a critical asset for professionals seeking to maintain strict thermal cycles and ensure weld quality in large-bore piping applications.

Technical Specifications and Compatibility

This induction blanket is designed for use with Miller ProHeat power sources. Operators should ensure that the blanket length matches the circumference of the workpiece to maintain proper coupling. The 129-inch length is tailored for 38-inch pipes, providing full coverage without excessive overlap or gaps that could lead to uneven heating. The unit is backed by Miller's True Blue warranty for 3 months, ensuring reliability and performance consistency.
