Abstract: A method for manufacturing a clad steel pipe is provided, wherein the clad steel pipe is manufactured by using a clad steel plate as a raw material. The clad steel plate comprises a base layer (1) and a clad layer (2) roll-bonded with the base layer (1). The method for manufacturing a clad steel pipe comprises the steps of forming, welding, and deburring; both sides of the clad steel plate are bent towards the base layer (1) side of the clad steel plate, then the forming step is carried out, and after the forming step, the opening faces of the resultant pipe blank are all in a form of the clad layer (2). According to the method for manufacturing a clad steel pipe, a clad steel pipe is manufactured by using a clad steel plate as a raw material. Thus, continuance and high efficiency of a high-frequency longitudinal welding pipe unit is fully utilized, subsequent non-continuous processes are not necessary, and the corrosion resistance at the weld of the clad steel pipe is ensured.

Abstract: Disclosed is a high corrosion-resistance strip steel and its manufacturing method. The high corrosion-resistance strip steel comprises a carbon steel base layer and a corrosion-resistance cladding layer roll-bonded with the carbon steel base layer, the corrosion-resistance cladding layer being austenitic stainless steel or pure titanium, the thickness of the corrosion-resistance cladding layer being 0.5% to 5% of the total thickness of the strip steel. The high corrosion-resistance strip steel has a high corrosion-resistance surface, good interlayer bonding performance, good mechanical properties and processability.
