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

Heat Pipes Faster with the Miller ProHeat Blanket

When you are out in the field welding pipe, the last thing you want to deal with is a complicated setup just to get your preheat right. The Miller ProHeat Air-Cooled Induction Blanket (Model #300074) is designed to make your life easier. Specifically sized for 18-inch pipe, this 9-inch by 66-inch blanket wraps perfectly around your workpiece to deliver consistent, even heat. The best part? It is 100% air-cooled. That means you don't have to drag around water coolers, check coolant levels, or worry about leaking hoses. You just wrap it, plug it into your ProHeat system, and you are ready to go.

We know that welding environments are tough on gear. You're dragging cables over concrete, grating, and rough metal edges all day. That is why Miller includes a heavy-duty Kevlar sleeve with this blanket. The Kevlar layer acts as a shield, protecting the sensitive induction coils inside from cuts, scrapes, and burns. It’s built to handle the abuse of a shipyard or a pipeline right-of-way. And if you do manage to wear the sleeve out after months of hard use, you don't have to trash the whole blanket—you can simply swap out the sleeve for a new one and keep working.

This blanket is rated for temperatures up to 400°F, which covers the preheat requirements for most carbon and alloy steel jobs. It’s incredibly efficient, transferring over 90% of the energy directly into the pipe, so you aren't wasting power or waiting forever for the metal to come up to temp. Whether you are welding pressure vessels, structural steel, or process piping, this tool helps you hit your interpass temps accurately and maintain the quality your QC inspector is looking for. It’s lightweight, flexible, and built by Miller, so you know it’s ready to work as hard as you do.

Stop struggling with flame heating or cumbersome water-cooled jackets. Upgrade your preheat game with the Miller 300074 and experience the speed and convenience of air-cooled induction heating. It’s the smart way to ensure your welds pass X-ray every time while saving you time on setup and teardown.
