The ability of Spiral pipe to handle high
pressures, its efficient airflow characteristics,
and its low pressure
loss make Spiral

joints, diverter valves, quick disconnects,
and air actuated gates. See pages 45-49 for
components and technical data.
Spiral Manufacturing offers a complete line of seam
welded, slip-joint fittings designed especially for
use with Spiral pipe. Standard fittings include
many types of elbows, crosses, tees, laterals, reducers,
and other components fabricated from
standard 20 gauge steel (other gauges available).
When you have requirements that cannot be
met by our standard fittings, we can fabricate
special fittings based on your specifications on
a time and materials basis. Once accepted for production, orders for special fittings cannot be
canceled, nor can the finished fitting be returned for credit. Please! Check your measurements
of light gauge
metal with a spiral
lockseam construction that assures maximum
strength and rigidity. Because 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, and
has a resistance to crushing approximately
2-1/2 times that of longitudinal lockseam
or welded pipe. Optional corrugations are
available which increase the rigidity of the
pipe by approximately 300%.
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.
Standard length in all diameters is 10 feet.
Any length between 6 and 20 feet cut at no
additional charge. Sizes range from 3” to 18” @ 1” intervals and 20” to 80” @ 2” intervals.
