Our patented U-Tube Projectile Tube Cleaners represents a smaller version of our Metal Projectile and is specifically designed for u-tube heat exchanger cleaning. The miniature design makes it possible to navigate tight radii found in u-tube heat exchangers. The design also utilizes a central, delrin pin which allows for greater flexibility when bending around radiuses. This design allows the entire tube to be cleaned not just the straight sections of the tubes. U-Tube Projectiles are available for heat exchanger tube sizes ranging from 5/8” to 1” (15.875mm to 25.400mm) outer diameter (O.D.) and may be available for larger diameter tubes based on special requests.
Listed below is a diagram that shows the minimum radius that the 5/8” and ¾” U-Tube Projectiles will not pass:
