摘要： For simply and surely manufacturing a double wall corrugated pipe having a socked part of a predetermined shape without any deformation, in a method for manufacturing a double wall corrugated pipe 1 having a slot part 3 on one end and a socket part 2a on the other hand, an external wall 11 (21, 31) of a continuous irregular circular shape, and an inner wall 12 (22) of a cylindrical shape by subjecting a thermoplastic resin to extrusion molding, before the double wall corrugated pipe 1 to be extrusion-molded is cooled off, a pore is formed in an external wall 21 portion of the socket part 2a by piercing with a needle 5 to allow a hollow chamber 23 of the socket part 2a to communicate with the air, so as to be designed to surely prevent shrinkage or deformation of an external wall 21 of the socket part 2b accompanied by a decrease in temperature.
