Our spiral pipe, the ultimate in pressure-tight circular tubes of superior quality, is fabricated in exact sizes using galvanized steel. The pipe consists of a smooth interior for low friction loss and a 4-ply spiral lockseam entirely on the outside for high strength and rigidity. Dust collection system duct is manufactured with heavier gauges than normal air conditioning duct work. Fittings are two gauges heavier than the spiral duct.
A wide variety of round fittings are produced by ADMP for High Pressure, including 90, 60, 45 and 30 degree elbows as standards (75, 15 and other degree angles are also available), tees, laterals, reducing laterals, reducers, couplings, end caps, crosses, etc. We also stock clean-out caps, in-line clean outs, floor sweeps, and blast gates. Standard fitting ends butt up against the spiral pipe and female couplings are used so that fitting or pipe ends do not protrude into the air stream.
Lapping of seams are in the direction of air flow. The finest continuous weld seams are made with Metal Inert Gas Shielded Welds (MIG). Welded seams are sprayed with aluminum paint containing rust inhibitor for added corrosion protection.
45 and 90 degree elbows 4” through 10” diameter are smooth die-stamped type. For elbows, a wide variety of different radii are available; one and one-half diameter to centerline is standard.
Particular attention is given to the entrance for conical tees, straight tees, and laterals. These fittings have a rounded entrance edge. They are not butt welded square entrance contractor type fittings.
Fittings are machine cut on our State-of-the-Art Vulcan Plasma cutting table, assuring manufacturing tolerance consistency. Our spiral pipe is produced on our State-of-the-Art spiral pipe machine of proven performance.
