概述：
    钢-钢复合双金属管道内衬采用耐磨铸钢，该产品既具有高合金铸钢的耐磨、耐腐蚀特性（耐磨、耐蚀性较16Mn无缝钢管提高30倍以上），又有较高的机械强度和较高的抗冲击性能，复合的双金属是冶金结合，使用安全可靠。
    耐磨铸钢选用铬系白口铸钢，是一种抗磨性很好的铸钢，在一些场合下使用已显示出重大的优越性。对于在有腐

Overview：
    Steel clad steel double metal pipe lined with wear-resistant cast steel, the product has not only high wear-resistant alloy cast steel, corrosion-resistant properties (wear resistance, corrosion resistance than 16Mn seamless steel tube increased more than 30 times), and the impact properties of high mechanical strength and high, double metal composite is metallurgical combination, the use of safe and reliable.
    Chromium cast white cast steel is a kind of wear-resistant cast steel. It is a kind of cast steel with good abrasion resistance. It has shown great superiority in some occasions
