Steel lining polyurethane wear-resisting pipe is a pipeline of high wear resistance, high pressure, high resistance to erosion. It is made by carbon nano-materials and special polyurethane adhesive sticky body, coupled centrifugal casting technology and carbon nano-curing technology, using a pressure pipe carrier, in the pipe wall lining on a layer uniform, smooth polyurethane carbon nano-resistant material, and special production technology and processing techniques composite. Particularly applicable to concentrate liquid transportation.
