Brushes, mounted on solid-cast and steel-mandrel pigs, are used for abrasive pipeline cleaning where millscale, rust, sand, wax, paraffin, sludge, mud and debris exist. Prostran bristles allow for pipeline cleaning of plastic and internally coated pipe applications. Designs include wire-wheel, circular, spring-mounted, and wrap-around manufactured in carbon steel, stainless steel, and prostran (plastic) flat-wire or round-wire material. Brush replacements are available for ALL manufacturer’s pig styles — ours as well as others.
