Making duct material is essential to ensure the cleanliness of the air conditioning material selection. Clean air conditioning duct systems generally use galvanized steel processing. Should be of high quality galvanized steel plate plant decontamination, galvanizing layer standards should> 314g / m2, and should be uniform coating, free from the shell, no oxidation. hangers, reinforced frame, bolts, washers, duct flanges, rivets should be galvanized fittings, flanges and gaskets should be flexible, not produce dust, there certain intensity soft rubber or latex sponge, external insulation duct can be more than 32K flame density PE board to special glue, glass wool and other fiber products should not be used. material procurement. material procurement plan must be in accordance with the choice of varieties kinds of products have quality assurance manufacturer's product. Also note that the physical examination of material specifications, materials, finish, sheet should also check the flatness of the corners of the square clean room decontamination, zinc coating adhesion degree After the purchase of materials during transport should also keep intact packaging, moisture-proof, anti-shock, anti-pollution. Materials custody. Clean air conditioning materials should set up a dedicated warehouse, or a centralized repository. repository should be clean, no pollution, avoid damp, In particular valve, outlet, muffler and other parts should be stored tightly packed. Clean air-conditioned warehouse storage materials to shorten the time, should be used with the purchase. produced wind workable whole plate should be transported to the site, to avoid moving parts pollution caused by the way. duct cleaning system make the point. After processing of semi-finished products should be scrubbed again into the next process, the duct should be formed immediately after cutting seams combination, not long put. duct flange process to ensure that the flange plane smooth, specifications must be accurate, and duct match to guarantee duct sealing connection interface combination. duct bottom horizontal joints shall not have, and try to avoid longitudinal seams purification plant engineering company, duct size should be large to the entire plate production, minimize ribs, stiffeners also must be located not use beading strengthening ribs in the duct. duct should be making use of joint angle or corner seams, 6 above shall not be used by the clean air duct Button seams. seams at the zinc coating is damaged, the rivet holes and galvanized layer damaged flange weld corrosion must make do. duct flange joints and cracks around rivet holes should be coated with silicone seal The wind pipe flange must be smooth uniform. flange width and rivet holes, screw flange must be in strict accordance with specifications for flexible short pipe must be smooth wall, generally use leather or plastic, duct inspection door with a soft padding rubber.
