SUS304/ Teflon Coating Concentric Reducer

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.

Note:

Duct diameter over 2000mm is available on request.

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 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.

2. 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.

3.100% total quality inspection (film thickness detection, pinhole detection), with film thickness tester to detect coating film thickness. The film thickness is 260±30 μm. A pinhole detector is used to detect whether the coating has pinholes. Adjust the standard detection voltage to 2.5KV, if there are needles that need to be repaired or reworked. The film thickness and pinhole test results after quality inspection should be recorded in the "Duct Coatung Quality Inspection Form".

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.
