When line flow can temporarily be stopped for controlled freezing, and particularly where there is restricted work access at an industrial or commercial piping jobsite, XEL’s pipe freezing services offer the perfect solution for 1/2” through 48” piping systems—with hot water lines up to 230°F. This proven technology can isolate the problem valve, or faulty meter, with solid freeze plugs by freezing the fluid within the line. It requires no drain down or refill and no loss of expensive process fluids. The procedure can be completed on a wide variety of pipe materials and product fluids. Then the plugs are simply thawed and the line is put back into operation immediately. Pipe freezing is an extremely economical temporary plugging technique in appropriate applications, cutting your line plugging costs in half.
