Spiral Manufacturing Co.

spiral pipe combines the economies of light gauge metal with a spiral lockseam construction that assures maximum strength and rigidity. as a result of its superior structural strength, the ductwork requires fewer joints and hangers. four plys of metal form a continuous interlocked reinforcing rib on the outside which permits making long lengths of pipe in various diameters from strip stock of specified gauge. developed for use on high velocity, high pressure air conditioning systems, spiral pipe has gained wide acceptance for all types of high or medium pressure, above and below ground distribution systems, such as ventilation, dust removal, grain handling, carbon monoxide exhaust and dual wall pipe for sound and thermal insulation. these are only a few of its diversified applications. spiral pipe is available in other materials on special order, such as vinyl-coated steel, brass, copper, aluminum and stainless steel. spiral galvanized pipe is carefully engineered and built, to meet or
