Abstract: A method and apparatus for electrostatically bonding coaxial tubing. An outer tube comprises an electrically conductive material and has an inner surface. An inner tube comprises material and has an outer surface. The inner tube and the outer tube are positioned to define a channel. A bridging structure comprising an electrically conductive material is positioned such that the bridging structure forms mechanical contact and an electrostatic connection between electrically conductive material on the tubes. The bridging structure is in mechanical contact with the inner surface of the outer tube at a first plurality of points and in mechanical contact with the outer surface of the inner tube at a second plurality of points.

Abstract: A method and apparatus for insulating a fluid line in a container configured to contain a fluid. The apparatus comprises a container, a fluid line in the container, and a tube. The container is configured to contain a fluid. The tube is placed around the fluid line in the container to form a channel around a first portion of the fluid line. The tube is configured to contain the fluid from the container in the channel and to prevent a first flow of the fluid between the container and the channel except through a number of ends of the tube. The tube is further configured to reduce a second flow of the fluid within the channel such that the fluid in the channel insulates the fluid line.

Abstract: A method and apparatus comprising a structure. The structure is configured to be placed around a fluid line in a container that is configured to hold a fluid. The structure is further configured to reduce a flow of the fluid within a volume of the structure such that the fluid in the volume insulates the fluid line.
