Note:
1. Duct diameter over 2000mm is available on request.
2. Duct thickness is built on smacna °round industrial duct construction standards** classes 1 and 5 at pressure -2500pa (-10 in.Wg) .And it also can be changed as customer's request.
1. The straight duct welding bead must be smooth, to achieve single-sided welding and double-sided forming, the interior must be polished smooth, no pores, and the folding edge of the folding surface should be flat (about 90°).
2. The part of the air duct to be painted (including the flange surface inside the pipe) must be sandblasted, the sandblasting roughness must meet the roughness of 3.0 G/S76, 40μm or more, and the residual sand particles and metal dust outside the pipe must be removed after sandblasting. Confirm whether the surface of the duct workpiece is clean and the workpiece is covered with aluminum foil.
3. Pull the pipe fittings into the coating room, start painting, spray with electrostatic powder coating machine and extended spray gun tube, adjust the sintering time moderately according to the characteristics of raw materials for 15~20 minutes, and the sintering temperature range is 285°~300°C.
4.Duct diameter over 2000mm is available on request. Duct thickness is built on SMACNA. And it also can be changed as customer’s request.
Ductwork
1. The exterior metal material is 304 or 316 stainless steel.
2. Before coating, the stainless steel substrate is checked to ensure complete welds and proper surface treatment.
3.Coating material is ETFE fluoropolymer thermoplastic resin.
4. The thickness of coating is on an average of 260μ.
5. The pin hole test performance conducted by a DC spark tester at 2.5KV/260μ to ensure a pin nole free protective coating.
