Miller ProHeat Induction Blanket for 90-Inch Pipe Preheating

Efficient Preheating for Large Bore Piping

When tackling massive welding projects involving 90-inch pipes, consistent preheating is not just a requirement—it is the foundation of a quality weld. The Miller 301620 Induction Blanket is designed to take the headache out of heating large diameters. Unlike open flames that struggle with wind and inconsistency, or resistance pads that take hours to set up, this induction blanket wraps easily around your workpiece and delivers heat directly into the metal. The result is a uniform temperature throughout the pipe, reducing the risk of hydrogen cracking and ensuring your welds meet the strictest radiographic standards.

Built for the Field
Field work is tough on equipment, which is why this blanket comes equipped with a durable protective sleeve. This sleeve shields the blanket from the rough surfaces of raw pipe and the general wear and tear of the job site, extending the lifespan of your investment. Measuring 312 inches long, it is perfectly sized to encircle a 90-inch pipe, providing full 360-degree heating coverage without the need for complex daisy-chaining of smaller heating elements.

The Induction Advantage
Using the Miller 301620 with a ProHeat system transforms your workflow. You get faster time-to-temperature, meaning less downtime waiting for the pipe to get hot and more time dropping beads. The setup is cleaner and safer, with no open flames or explosive gases to manage. Whether you are working on a cross-country pipeline or a facility expansion, this induction blanket offers the reliability and performance professional welders demand for heavy-wall, large-diameter applications.
