DOUBLE-WALLED PIPE CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To provide a method capable of easily manufacturing a double-walled pipe provided with an inner pipe and an outer pipe, the double-walled pipe provided with the manufacturing method, and its use. SOLUTION: The double-walled pipe provided with the inner pipe and the outer pipe is manufactured by winding a wire so as to touch an outer circumference face of the inner pipe, and forming the outer pipe by combining components of the outer pipe plurally divided along a longitudinal direction, such that an inner circumference face of the outer pipe touches the wire. Winding of the wire is carried out spirally, and such that the wires do not touch each other. COPYRIGHT: (C)2008,JPO&INPIT
