METHOD FOR CONTINUOUSLY MANUFACTURING FLUID TRANSFER PIPES AND A PIPE CONNECTOR MANUFACTURED BY THE SAME, CAPABLE OF IMPROVING THE DURABILITY AND STRENGTH

摘要

PURPOSE: A method for continuously manufacturing fluid transfer pipes and a pipe connector manufactured by the same are provided to increase the strength by spirally installing stiffening members between inner and outer pipes.;CONSTITUTION: A method for continuously manufacturing fluid transfer pipes is as follows. A nonwoven fabric(3) is wound around a mold(2) after being impregnated with mortar(4). An inner pipe is formed by flatly processing an outer surface of the wound nonwoven fabric. Stiffening members(6) are placed at constant intervals, and wound around the outer surface of the inner pipe. The nonwoven fabric is wound around the upper part of the stiffening member. An outer pipe is formed by flatly processing the outer surface of the wound nonwoven fabric. The fluid transfer pipes consisting of the inner and outer pipes are cut at the constant interval.;COPYRIGHT KIPO 2013
