THERMACOR’S STEEL-THERM is a factory-fabricated, pre-insulated piping system created by combining our popular FERRO-THERM line with Ductile Iron Couplings to seal the joints between lengths of pipe. The D.I. Couplings eliminate welding and provide compensation for expansion and contraction, thereby eliminating the need for expansion loops or expansion joints.
