300073 - Miller ProHeat Air-Cooled Induction Blanket 9x72 for 20-inch Pipe

High-Efficiency Preheating for Industrial Applications

The Miller ProHeat Air-Cooled Induction Blanket (Stock No. 300073) represents a significant advancement in thermal management for welding and fabrication environments. Designed specifically for use with the Miller ProHeat induction heating systems, this accessory is engineered to deliver consistent, controlled preheating for pipes with a 20-inch diameter. By utilizing air-cooled technology, this blanket eliminates the logistical challenges and maintenance requirements associated with liquid-cooled systems, such as coolant management, hoses, and chillers. This reduction in ancillary equipment not only lowers the total cost of ownership but also simplifies the setup process in complex field environments like pipelines, refineries, and shipbuilding sites.

With dimensions of 9 inches by 72 inches, the blanket provides optimal coverage for 20-inch pipes, ensuring uniform heat distribution which is critical for maintaining code-compliant interpass temperatures and preventing hydrogen cracking in high-strength steels. The unit is rated for temperatures up to 400 degrees Fahrenheit, making it an ideal solution for preheating applications where moderate thermal soaking is required before welding. The system boasts an operational efficiency of over 90 percent, translating to lower energy consumption and faster time-to-temperature compared to traditional resistance heating or open-flame methods.

Durability in harsh industrial settings is addressed through the inclusion of a replaceable Kevlar sleeve. This high-performance material offers exceptional resistance to cuts, abrasions, and tears, protecting the induction coil elements within the blanket from the rough surfaces of raw pipe and structural steel. This protective layer extends the service life of the blanket and ensures reliable performance over repeated uses. Whether utilized in pressure vessel fabrication or structural welding, the Miller 300073 induction blanket offers a robust, efficient, and flexible heating solution that meets the rigorous demands of modern industrial welding standards.

Integration with the ProHeat system allows for precise temperature control and data logging capabilities (depending on the power source), ensuring that quality assurance protocols are met with ease. The flexibility of the blanket allows it to conform to both thin and heavy-wall parts, providing versatility across different project specifications. By choosing the air-cooled option, facility managers and project engineers can streamline their heating operations while maintaining the high quality expected from Miller Electric equipment.
