What are the advantages of firm sealing in air duct production

1. Because the air duct production line manufacturers and construction are not in the same site, so the air duct production lines produced in the production workshop are semi-finished products. After the semi-finished products are numbered reasonably in order, they are moved to the construction site and installed again.

2. Generally speaking, the connection between the air ducts is carried out by the way of joint angle bite, so that the air ducts will have good sealing in the future.

3. For the connection between the branch pipe and the main pipe, the joint bite or the reverse side is used to rivet with the main pipe. The joints are sealed with glass glue to prevent air leakage. 4. For the pipe flange to flange, TFD flange angle is used, and then it is hammered into the flange and connected by bolts.
