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

Tough, Simple, and Effective Preheating

When you are out in the field or on the shop floor, the last thing you want to deal with is a complicated setup just to get your pipe up to temp. The Miller ProHeat Air-Cooled Induction Blanket (300073) is built to make your life easier. Designed specifically for 20-inch pipes, this 9-inch by 72-inch blanket wraps perfectly around your workpiece to deliver fast, consistent heat exactly where you need it. Because it is air-cooled, you don't have to mess around with water lines, coolers, or wet messes. You just hook it up to your Miller ProHeat system, wrap it, and you are ready to weld. It’s a grab-and-go solution that saves you time on setup so you can focus on laying beads.

We know that welding environments are brutal on gear. Dragging equipment across concrete, jagged metal, and through the mud can destroy flimsy tools in a day. That is why this induction blanket comes standard with a replaceable Kevlar sleeve. This tough outer layer acts as armor for the heating coils inside, protecting them from cuts, scrapes, and tears. If the sleeve eventually gets worn out from heavy use, you can replace just the sleeve without having to buy a whole new blanket, saving you money in the long run. It is rated for preheating up to 400 degrees Fahrenheit, which covers a huge range of standard preheat requirements for carbon and alloy steels.

The flexibility of this blanket is a huge plus. Unlike rigid heating pads or ceramic mats that can be a pain to position, the Miller induction blanket conforms easily to the pipe surface. This ensures that the heat transfer is efficient—over 90% efficient, in fact—so you aren't wasting power or waiting forever for the steel to soak. Whether you are working on a pipeline, in a shipyard, or fabricating pressure vessels, this tool helps you maintain the right interpass temperature without the hassle of open flames or propane torches. It keeps the heat in the part and keeps you safer and more comfortable while you weld.

Stop fighting with outdated heating methods. The Miller 300073 blanket gives you the professional edge with reliable, even heating that helps prevent cracking and ensures your welds pass X-ray every time. It’s lightweight, durable, and backed by Miller’s reputation for quality. Add this to your rig and experience the difference that proper induction heating makes on your productivity and weld quality.
