As the corrugated steel pipes has many advantages to compensate for the shortcomings of the concrete fume pipes, it has been widely used for culverts and drain trenches. However, when corrugated steel pipes used as a sewage pipe or in an environment exposed to sea water, corrosion can cause problems and degradation of the function of pipe. So, Composite Corrugated Steel Pipe(CCSP) coated with three layers were developed to compensate for the shortcomings and improve performance of corrugated steel pipes. The composite material used in fabrication of the CCSP consists of a three layer polymer protective coating on both sides of a steel sheet core. To verify the field application of the CCSP, a test was conducted on the resistance of the strain, stability of connections, water flow performance and durability to determine whether they meet KS quality and various design standards.
