Thermometal abrasion-resistant composite pipe

The invention belongs to the technical field of material machining and particularly relates to a thermometal abrasion-resistant composite pipe. The outer wall of the thermometal abrasion-resistant composite pipe is made of ordinary steel, and the lining of the thermometal abrasion-resistant composite pipe is made of a high-chrome abrasion-resistant alloy material. The high-chrome abrasion-resistant alloy material is composed of, by weight, 2.7-3.0 parts of C, 0-1.0 part of Si, 0.5-0.8 part of Mn, 25.0-30.0 parts of Cr, 0-0.10 part of P, 0-0.06 part of S, 0.5-1 part of Ni, 0.5-1 part of Mo, 1-2 parts of Cu, 0-0.5 part of Re, 0.2-0.4 part of V and the balance Fe and impurities. The total amount of the impurities is less than or equal to 0.1. The outer wall of the composite pipe is made of the ordinary steel, and the lining is made of the high-chrome abrasion-resistant alloy material, so that good metallurgical bonding is formed; the characteristics including abrasion resistance and corrosion resistance of high-alloy materials are achieved, and high mechanical strength and high shock resistance are achieved as well.
