Vacuum-insulated pipe assembly

Abstract

A vacuum-insulated pipe assembly having an outer pipe and an inner pipe within the outer pipe, the inner pipe distanced from the outer pipe to provide a space, the space evacuated to define a vacuum. The vacuum-insulated pipe assembly has an annular wall extending inwardly from the outer pipe and defining an aperture about a central axis, the annular wall defining a closed end of the space. The vacuum-insulated pipe assembly has a first connector connected to the inner pipe, and a second connector extending through the aperture and connected to the first connector. The first connector and the second connector are each hollow and connected such that the inner pipe is in fluid communication with the second connector through the aperture. Also a system and a method for making a vacuum-insulated pipe assembly.
