Air conditioning duct processing quality is directly related to  the quality of human breathing air, so Jinan air conditioning duct  processing must fit the corresponding norms.

       First,  the air conditioning duct appearance quality should reach the angle  straight, arc average, both ends parallel, no Qiaojiao angle, the  appearance of concave and convex not more than 5 mm; duct and flange  convergence strong, flanging smooth, width of not less than 6mm, tight The  flange of the air duct should be in line with the design requirements  and construction standards of air-conditioning duct processing, welding  should be strong, the weld does not set the screw hole, screw hole with  interchangeability; rectangular duct side length greater than 630mm insulation duct is greater than 800mm should be reinforced,  angle steel reinforcement should be arranged uniform, the average  symmetrical fixed strong.

Second,  the air-conditioning duct processing method can be used straight-line  method.Explanation method using parallel line method. According to the  large sample duct different geometric shape and specifications,  respectively, crossed and stop cutting. Before the mouth, the plate must be chamfered.

       Duct processing workers is the most important process of  quality control, in addition to processing materials, processing  technology, etc., Jinan air conditioning duct processing there are  certain operating conditions.

       1. Centralized processing should have a wide, bright, clean, air-smooth, non-humid plant.

       2. On-site decentralized processing should have the ability to  rain and snow, wind and strong structure of the equipment, and to ensure  that the site processing site regular and orderly.

       3. Work site should have the appropriate processing technology  of the fundamental equipment, equipment and power supply and a solid  security installation, and equipped with fire equipment.

       4.  Air conditioning duct processing should be approved drawings, the  inspection of the large sample, the system map, and the construction of a  written technical quality and safe delivery. As long as the air  conditioning duct processing in all aspects of control, The quality of processing to meet customer needs.
