介绍了一种制备不锈钢内衬复合钢管的新型工艺──SHS-离心技术;讨论了所制备的复合管材的组织和不锈钢层的性能。这种不锈钢复合管的内外层可实现冶金结合,SHS不锈钢抗腐蚀性能优于相应的常规不锈钢,该工艺具有节能、高效、设备简单等优点。
A new process for preparing stainless steel-lined composite steel pipe (HSS-centrifugal technology) is introduced. The microstructure and stainless steel layer properties of the prepared composite pipe are discussed. The inner and outer layers of the stainless steel composite pipe can be metallurgically bonded, and the corrosion resistance of the SHS stainless steel is better than the corresponding conventional stainless steel. The process has the advantages of energy saving, high efficiency and simple equipment.
