Code for construction, fabrication, installation and acceptance of ventilation ducts and accessories Code for Construction, Fabrication, Installation and Acceptance of Ventilation Duct Accessories Now, the application of ventilation ducts is quite common, and the application environment is very wide. How should the ventilation ducts be arranged? The exhaust points of the dedusting system should not be too many to facilitate the resistance balance between the branches. The dedusting air duct should be laid as vertically or obliquely as possible. When laying obliquely, the included angle with the horizontal plane should be greater than 45 degrees. If it is necessary to lay horizontally or the inclination is less than 30 degrees, measures should be taken, such as increasing the flow rate. Duct of ventilation system

Three reinforcement methods for ventilation pipe construction The construction reinforcement of the ventilation duct can ensure the stability of the internal static pressure of the ventilation duct in practical use. If the pipe wall presents 1% deflection, the ventilation duct needs to be opened for reinforcement. In the process of reinforcing ventilation ducts, it is required to select corresponding reinforcement methods according to the pressure and size. The selection of reinforcement methods plays a decisive role in the service life of ventilation ducts. Generally, the following methods can be used to open the reinforcement. One, pull rod
