300074 - Miller ProHeat Air-Cooled Induction Blanket 9x66 for 18-inch Pipe

Miller ProHeat Air-Cooled Induction Blanket Overview

The Miller ProHeat Air-Cooled Induction Blanket (SKU: 300074) is a high-performance accessory engineered specifically for use with Miller's ProHeat induction heating systems. Designed to facilitate the preheating of industrial piping and structural components, this blanket measures 9 inches by 66 inches, making it the precise dimension required for 18-inch diameter pipes. Unlike traditional liquid-cooled systems that require complex setups involving coolers, hoses, and coolant management, this blanket utilizes an advanced air-cooled design. This feature significantly increases flexibility on the job site and drops installation costs by eliminating the need for water cooling infrastructure.

Thermal management is critical in welding applications to prevent hydrogen cracking and ensure weld integrity. This induction blanket is rated for preheating applications up to 400 degrees Fahrenheit (204 degrees Celsius), making it suitable for a wide range of code-quality welding tasks. The unit boasts an operation efficiency greater than 90 percent, ensuring that energy is effectively transferred to the workpiece rather than being lost as waste heat. This high efficiency applies to both thin-wall and heavy-wall part applications, providing versatile performance across different project requirements.

Durability is a key concern in heavy industrial environments such as shipbuilding, pipeline construction, and refinery maintenance. To address this, the Miller 300074 comes equipped with a replaceable Kevlar® sleeve. Kevlar is renowned for its high tensile strength and resistance to thermal degradation, providing the induction coil with superior protection against abrasions, cuts, and tears that are common in rough working conditions. Should the sleeve eventually wear out, it can be easily replaced, extending the overall service life of the blanket itself.

This product is an essential tool for professionals in the pressure vessel, process pipe, and power plant sectors who require reliable, consistent heating solutions. By maintaining proper preheat temperatures, operators can ensure compliance with welding procedures and improve the mechanical properties of the final weldment. The blanket is backed by Miller's 3-month warranty, offering peace of mind and assurance of quality manufacturing.
