Pipe for transfering fly ashes having improved abrasion resistance

摘要

The present invention relates to a coal ash transport pipe, and more particularly, to a coal ash transport pipe having improved abrasion resistance of an inner wall surface for solid particles in a slurry to be transported. Coal ash transport pipe with improved abrasion resistance of the present invention has the advantage that the endothelial pipe is formed of a material having higher abrasion resistance and strength than the outer shell, thereby increasing the wear resistance at an economical cost. In addition, the abrasive transfer pipe with improved abrasion resistance of the present invention has a delay in abrasion since the direct contact of the solid particles to the inner wall surface of the endothelial tube is minimized as the solid particles in the slurry that are secondaryly introduced into the solid particles inserted into the recess are contacted. There is an advantage that the durability can be increased.
