双金属复合管的冶金复合是用爆炸复合、堆焊、双熔体工艺复合而成，其两复合界面是冶金熔合在一起。特征：复合界面带宽、熔合两种金属；复合牢固；导热、导音、导电没有界；冷热缩胀一致。
Metallurgical cladding of bimetallic composite pipe is made by explosive cladding, surfacing and double melt process. The two composite interfaces are metallurgical fusion. Features: Composite interface bandwidth, fusion of two metals; solid composite; heat conduction, sound conduction, conduction without boundaries; cold and heat shrinkage and expansion of the same.
这工艺复合的内衬不锈钢复合钢管，英国早在1967年开始试验，成功地开发了T310不锈钢外层和125号钢为内层得内衬不锈钢复合钢管等。
As early as 1967, the British began to test the process of composite stainless steel pipe lined with stainless steel. T310 stainless steel outer layer and 125 stainless steel inner lined with stainless steel composite pipe were successfully developed.
