Finite element analysis of residual thermal stress in ceramic-lined composite pipe prepared by centrifugal-SHS

The ceramic-lined composite pipe is a kind of high-performance, wear-resisting and anti-corrosion pipe. It is widely used in many fields such as electricity, petrochemical industry, metallurgy, chemical industries, etc. In this study, the centrifugal-SHS process to prepare ceramic-lined composite pipe was briefly introduced. The temperature distribution and transformation during the cooling process of the ceramic-lined composite pipe preparation were emphatically analyzed with finite element numerical simulation. With the function of transient thermal analysis and thermal–structure coupling of ANSYS, the residual thermal stress of the composite pipe was numerically simulated. The effect of the thickness of SHS-layer on the performance of the ceramic-lined composite pipe was investigated as well. The results of numerical analysis indicate that reasonable adjustment of the thickness of SHS-layer could reduce the interfacial stress between any two layers so that the service life, safety and reliability of the ceramic-lined composite pipe would be improved.
