Dual containment system having coaxial flexible tubes for transporting a fluid through a “rolling loop” cable duct

摘要

Disclosed are systems and methods for a fluid transportation system having a first flexible tube with an inner wall. The fluid transportation system also has a second flexible tube with an outer wall. The second tube is located inside the first tube and a standoff is located between the inner wall of the first tube and the outer wall of the second tube. The first flexible tube is configured to transport a first fluid and the second flexible tube is configured to transport a second fluid. The first and second flexible tubes are configured such that the first fluid isolates the second fluid from an ambient environment, and the first fluid can be monitored for leakage.

1. A fluid transportation system comprising:
a first flexible tube having an inner wall and configured to transport a first fluid; a second flexible tube having an outer wall and configured to transport a second fluid, wherein the second tube is located inside the first tube; a standoff located between the inner wall of the first tube and the outer wall of the second tube; a distribution device comprising:
a chamber comprising chamber walls that are configured to define a path for a flow of the first fluid through the distribution device, wherein the second end of the first flexible tube is coupled to the chamber and the first flexible tube is located external to the chamber,a first fluid port configured to provide an opening for the first fluid to enter the chamber, anda second fluid port, located external to the first fluid port, configured to provide an opening for the second fluid to enter the second flexible tube; and a manifold including:
a first portion that is located inside the chamber, wherein the second end of the second flexible tube is coupled to the manifold and the second flexible tube is located external to the chamber; anda second portion that is located outside the chamber.
