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.

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 exceed all SMACNA standards (Sheet Metal And Contractors National Association).

We at Spiral Manufacturing Co., Inc. feel there is no job, be it large or small, that we can’t provide you the best quality and service available. Our commitment to you, is the future of this company. Thank you for your business and the opportunity to serve your needs.

Spiral Pipe for Many Applications

Spiral pipe is a workhorse in the modern HVAC, aerospace, and manufacturing industries. Engineers who chose spiral pipe gain the benefits of a spiral lockseam construction, ensuring maximum rigidity and strength. Not only does it offer exceptional structural strength, spiral ductwork requires fewer hangers and joints. Spiral pipe also facilitates manufacture of long pipe lengths in various diameters due to the four-ply metal construction which provide a continuous interlocked reinforcing rib on the outside of the pipe.

Spiral pipe was developed for use on high pressure, high velocity air conditioning systems and is widely used for various types of medium or high pressure, below and above ground distribution systems – this includes those for dust removal, ventilation carbon monoxide exhaust, grain handling, thermal insulation, and dual wall pipe for sound, among others.
