Article Preview

Recently a new method for manufacturing bimetal clad pipes is introduced, which can integrate centrifugal casting with extrusion technology organically. Through experimental study on microstructure and properties of bimetallic clad pipes manufactured by centrifugal casting and extruding, the results indicates that bimetal clad pipes with intact metallurgical interface have good bonding properties. Meanwhile wider interfacial zone will be favorable for reducing deformation stress. However there are still a few technical difficulties about the bimetallic clad pipe. Due to chemical composition and properties difference between backing materials and CRA layer, chemical elements will spread and microstructure will change during the process of production and even mechanical behavior of backing metal pipe and corrosion resistance of CRA layer will decline. To meet application requirements, appropriate heat treatment with bimetal clad pipes seems vita.
