Abstract
Freeze damage to pipes containing liquids is accomplished by including in the interior of the pipe an elongated section of tubing sealed at each end and containing internally an inert gas under pressure; a means for attaching one end of the tubing to the pipe to prevent linear axial movement of the tubing and a means at the other end of the tubing to maintain it concentrically within the pipe and to permit safe linear axial expansion of the tubing.
