Our Single Spiral Steel Tube Brushes are engineered for powerful, aggressive cleaning and descaling inside pipes, bores, and tubular structures. Constructed with high-carbon steel or stainless steel wire arranged in a robust single-spiral pattern, this design provides maximum filament density and rigidity for impactful scraping and cutting action against tough contaminants.
Ideal for removing heavy rust, welding slag, hardened deposits, and old coatings from the interior of industrial piping, structural tubes, and large-diameter cylinders. They are a fundamental tool for maintenance, rehabilitation, and surface preparation in sectors like shipbuilding, heavy equipment repair, oil & gas, and construction.
