Note:
1. Duct diameter over 2000mm is available on request.
2. Duct thickness is built on SMACNA "round industrial duct construction standards0 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. Duct diameter over 2000mm is available on request. Duct thickness is built on SMACNA. And it also can be changed as customer’s request.
