Carbon steel is known for high strength and rigidity, while stainless steel has anticorrosion and antiwear properties. Given these characteristics, composite steel pipe, which is made from both kinds of steel, is widely used in pressure vessels and the petroleum chemical industry. Selecting carbon steel as the outer layer and stainless steel as the inner layer, this approach can not only ensure that the composite steel pipe has better mechanical properties, but can also reduce the cost of production. The thickness of the different steel layers serves as an important parameter for the evaluation of the safety performance of composite steel pipe. Because some measurement techniques can cause damage to the workpiece, nondestructive testing is preferred.
