Brushes are made of high-quality low-carbon wire: steel, brass plated, brass and stainless steel.
Twisting the wires in the harness significantly increases the hardness and elasticity of the cleaning elements of the brush. Unlike brushes made of parts of steel cables, the twisted harness in each brush element is better pressed against the inner surface of the pipeline. This ensures a high quality of cleaning while reducing wear of the brush and therefore increases the mileage of the cleaning PIG.
At the end of each harness there is an extension that is called "rose". This increases the surface area cleaned by every harness.
If necessary, two, three or more brush discs can be arranged at a minimal distance one after another. This increases the stiffness of the brush even further. Because the harnesses support each other. And the contact pressure of each cleaning element to the inner surface of the pipe increases significantly. Therefor increases the quality of removal of different solid deposits from the pipe surface. It also provides multiple passage of the cleaning elements over each millimeter of the pipe surface.
The number of brush disks on the PIG, landing dimensions, material and diameter of wire from which the cleaning harnesses are manufactured, as well as other parameters of the brushes can be discussed when ordering.
Also it is possible to manufacture circular non-twisted brushes made of non-metallic materials for cleaning of the pipes with internal coating.
