METAL/RESIN COMPOSITE PIPE THAT CAN BE EASILY WOUND INTO ANNULAR SHAPE, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention is a composite pipe manufactured by forming an adhesive layer and a resin layer at the outer surface of a metal pipe. The manufactured composite pipe is resistant to damage and the original form of the cross-sectional surface of the composite pipe can be maintained even when wound into an annular shape. Peeling, buckling, etc. does not occur even when the complex pipe is returned to the form of a straight pipe for construction. Thus, the present invention enables the advantages of the significantly superior constructability and transportability of the product.
