Dust Collection Ductwork Fittings and Components Oneida Dust Collection Ductwork. Engineered for performance and durability using heavy-gauge steel, our round, sheet metal ducting is built to withstand the high air pressures and constant abrasion created in dust collection and other material handling applications. HVAC Duct Construction Standards1.3 DUCT SEAL CLASS Ducts shall be sealed as specified in the HVAC-DCS:Review DCS pages 1-7 to 1-9. 1.4 DUCT LEAKAGE CLASS Consult the HVAC-Air Duct Leakage Test Manual and select appropriate allowable leakage. If field leak tests are required, appropriate test pressures and clear scope of testing must be specified. 1.5 DUCT LINER

Spiral pipe fittings can be connected using Spiral Pipe Adapters or by welding Angle
Roladuct Round Spiral Duct is manufactured by specialised spiral pipe mills in diameters from 76mm to 2500mm, and in wall thicknesses from 0.6mm to 2.0mm. Round duct systems enjoy the strongest natural shape for withstanding both internal and external pressure. Add to this a helical 4 ply lockseam (ie 4 x wall thickness) and you have a very SPIRAL DUCT & FITTINGS - Eastern Sheet MetalSPIRAL DUCT & FITTINGS Eastern Sheet Metal Rev.#4 7/16 and Eastern Poly Coated Steel (PCS).* Fittings are spot welded and/or gorelocked through 40 diameter. All larger fittings are continuously welded except for PCS fittings. Check with the plant when ordering. All fittings can be provided as continuously welded if required.

It is also less likely to leak due to it having fewer transverse & longitudinal joints when run in long, straight sections.

Ducting Options from US Duct Clamp Together Duct, Flange Ducting, US Tubing, and Spiral Duct. Where most other types of ducting are formed from sheet metal, spiral duct pipe is formed from a coil of metal into a rigid steel tube with a 4-ply spiral lock seam.It has a relatively smooth interior for low friction loss with the grooved seam entirely on the outside. Spiral Ductwork McMaster-CarrA spiral seam makes this duct strong and rigid. Fittings have male ends with a slightly smaller diameter to press-fit into duct.. Galvanized steel has good corrosion resistance. PVC-coated steel combines the strength of steel with the corrosion resistance of plastic. 304 stainless steel is more corrosion resistant than steel..

Spiral Pipe Applications - Industrial and CommercialSpiral 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).
The duct to which these flanges are attached is available in sizes 3" and up, and also in black iron, galvanized or SS. Construction methods range from laser welded pipe and mechanically lock elbows in lighter gauges to fully welded product in heavy gauge (even up to 1/4
