300060 - Miller ProHeat Air-Cooled Induction Blanket for 52-Inch Pipe

Technical Overview of the Miller ProHeat Air-Cooled Induction Blanket

The Miller ProHeat Air-Cooled Induction Blanket (SKU: 300060) is a specialized accessory engineered for use with Miller's ProHeat induction heating systems. Designed to facilitate efficient preheating of industrial piping, this specific model measures 7.5 inches in width and 173 inches in length, making it perfectly sized for wrapping around 52-inch diameter pipes. The blanket utilizes air-cooling technology, which simplifies the setup process by removing the need for liquid cooling lines and chillers often associated with higher-temperature induction applications. This air-cooled configuration is rated for preheating applications up to 400 degrees Fahrenheit (204 degrees Celsius), making it suitable for a wide range of structural and pipeline welding requirements.

Technically, the blanket is constructed to offer high electrical efficiency, boasting an operation efficiency rating of greater than 90 percent. This ensures that the majority of the energy drawn from the power source is effectively converted into heat within the workpiece, minimizing energy waste. The flexibility of the blanket allows it to conform tightly to the workpiece, whether the application involves thin-walled tubing or heavy-wall pressure vessels. This close contact is critical for induction heating, as it ensures uniform magnetic field coupling and consistent temperature distribution across the heat-affected zone.

Durability is a key focus of the design. The blanket comes equipped with a replaceable Kevlar sleeve. Kevlar is chosen for its exceptional thermal stability and resistance to mechanical damage. In industrial environments such as shipyards or refineries, equipment is frequently dragged across rough surfaces or exposed to sharp edges. The Kevlar sleeve acts as a sacrificial protective layer, shielding the internal induction coils from abrasion, cuts, and tears. This modular approach to protection allows users to replace the sleeve rather than the entire blanket if the outer layer becomes damaged, thereby reducing long-term maintenance costs. The product is backed by Miller's 3-month warranty, ensuring reliability and performance consistency.
