Steel lined polyurethane wear-resistant pipe is a kind of high wear resistance and high-voltage transmission pipe. It is compounded by the recommended foreign advanced carbon nano polyurethane raw materials and a special glue stick body, with advanced centrifugal casting forming technology and carbon nano vulcanization technology. Steel lined polyurethane carbon nanotubes wear-resisting pipe selects steel pipe as bearing carrier, and all the internal wall lined with a layer of uniform, smooth polyurethane carbon nano-resistant material.
