The double flat-walled steel-plastic composite winding drainage pipe is made of preformed strips using polyethylene as the main raw material. The strips are wound on the pipe forming machine and welded into pipes. At the same time, the galvanized steel strips are embedded into the shaped steel strips. In the groove between the two strips, the steel strip is simultaneously covered with the third generation new steel-plastic drainage pipe to become the outer wall of the pipe. The double-flat-wall steel-plastic drainage pipe technical system has obtained a Chinese patent and passed the testing of the National Chemical Building Materials Testing Center.
