Sheet Metal Duct<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">6. For the combination of semi-finished products of inner pipes, components, and accessories, the dirt at the site shall be removed first. After the combination riveting, the gaps and holes shall be blocked with glue or tin. The flange\u00a0width is consistent, greater than 7mm, and the screw hole is not covered; The flatness is less than 1mm. The finished products shall be stored horizontally by category, and attention shall be paid to protect the paint from wear; For the air duct to be reinforced, the stiffener is only allowed to be set on the outer wall.

When making the sheet metal air duct, the material shall be cut according to the plate to minimize the joints. The specific provisions are as follows: there shall be no joints within 800mm of the bottom edge width of the rectangular air duct, there shall be only one joint within 800mm-1000mm, and there can be two joints within 2400mm. Transverse splicing is prohibited for all the above dimensions, and the ratio of the long side to the short side of the rectangular air duct shall not be greater than 4:1; Sheet Metal Duct<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The butt joint shall be of a single flat type.

Cleaning of air duct: the cleaning of the air duct is particularly important. Generally, the galvanized steel plate has not been decreased, and the surface of the steel plate is coated with a large amount of grease. If it is not cleaned, it will be contaminated with dust during transportation, installation, and subsequent operation. During long-term use, it may lead to dust accumulation and flying, resulting in a sudden increase in the dust concentration in the air in front of the filter, This has a very adverse impact on the use of high-efficiency filters. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cleaning is mainly dust removal and degreasing. Clean water or pure water plus neutral cleaning agent shall be used for dust removal, and trichloroethylene or industrial alcohol shall be used for degreasing.
