Document Type and Number:
Japanese Patent JP2021093937
Kind Code:
A
Abstract:
To provide a multiple pipe suitable for obtaining a multi-layered tube in which each layer of gel is clear.SOLUTION: A multiple pipe 2 comprises a first fluid flow path 3A for flowing a first fluid A, second fluid flow paths 3Ba, 3Bb for flowing a second fluid B that gels by a reaction with the first fluid A, and a third fluid flow path 3C for flowing a third fluid C that does not turn into gel. The flow path 3C passes inside a pipe K1 with the smallest diameter. The flow path 3A and flow paths 3Ba and 3Bb pass between the n-th pipe with the smallest diameter and the n+1-th pipe with the smallest diameter. The flow path 3Ba and 3Bb are located on the flow path 3C side of the flow path 3A. Each of the flow paths 3A, 3Ba, 3Bb, and 3C is partitioned from other flow paths 3 over the entire length from the introduction port 5 provided on one end side of the multiple pipe 2 to the discharge port 6 provided on the other end side of the multiple pipe 2 by the wall of the pipe K constituting the flow path 3.SELECTED DRAWING: Figure 3
