Study on Radial Crushing Strength of Ceramic-lined Steel Composite Pipe

The theory of analysis of reinforced concrete beam is applied to the study of ceramic-lined steel composite pipe. A new formula of radial crushing strength of composite pipe is presented, which includes both the geometry sizes and the properties of the materials. The results obtained from this formula show thatthe greater the elastic modulus of ceramic lining is, the higher the radial crushing strength of the composite pipe is. This provides a valuable information for the structural design of the composite pipe.
