300068 - Miller ProHeat Air-Cooled Induction Blanket for 30-Inch Pipe

Technical Overview of the Miller ProHeat Air-Cooled Induction Blanket

The Miller ProHeat Air-Cooled Induction Blanket (SKU: 300068) is a specialized accessory designed for use with Miller's ProHeat induction heating systems. Engineered for high-efficiency preheating applications, this blanket measures 9 inches in width and 104 inches in length, specifically sized to accommodate 30-inch diameter pipes. It is capable of achieving preheat temperatures up to 400 degrees Fahrenheit (204 degrees Celsius), making it an essential tool for industries requiring precise thermal control during welding operations.

One of the primary technical advantages of this model is its air-cooled configuration. Unlike liquid-cooled systems that require chillers, coolant lines, and additional maintenance, this air-cooled blanket simplifies the setup process and reduces the overall footprint of the heating equipment. This design provides greater flexibility in field applications, particularly in pipeline, shipbuilding, and structural welding environments where portability is critical. The blanket operates with an efficiency rating of over 90 percent, ensuring that energy is effectively transferred to the workpiece, whether dealing with thin-walled tubing or heavy-wall pressure vessels.

Durability and protection are addressed through the inclusion of a replaceable Kevlar sleeve. This sleeve encases the induction coil, providing a robust barrier against abrasion, cuts, and tears that are common in harsh industrial environments. The Kevlar material is heat-resistant and tough, extending the service life of the blanket itself. This product is backed by Miller's 3-month warranty, ensuring reliability and performance consistency. It is an ideal solution for professionals in the refinery, power plant, and process piping sectors seeking to optimize their preheating procedures without the logistical burden of water-cooled systems.

Key Specifications and Applications

The blanket is designed to wrap securely around 30-inch pipes, providing uniform heat distribution essential for code-quality welds. Its application range covers a broad spectrum of industrial needs, including:

• Pipeline Construction: Ensures consistent preheat to prevent hydrogen cracking.
• Shipbuilding: Effective for large diameter structural components.
• Pressure Vessels: Maintains required interpass temperatures on heavy-wall vessels.
• Refineries and Power Plants: Ideal for maintenance and fabrication of process piping.

By utilizing induction technology, this blanket minimizes safety hazards associated with open flame heating, such as propane torches, while delivering superior temperature uniformity.
