Duct production line inspection is of great significance. It can improve the quality of duct production. Problems can also be found earlier. Therefore, the duct production line should be strictly inspected. Next, the ventilation pipeline production line will take you to understand the inspection aspects and the significance involved.
1. Cleaning systems for air pipe joints and pipes, and the joints of components, components, and static pressure must be tight and leak-tight; on the inner surface, the clean air piping system must be smooth and smooth, and it is forbidden to have transverse joints and reinforcement methods for reinforcing steel bars or ribs inside pipes.
2. duct production line pipe flange, flange bolt, and rivet hole spacing should not be greater than 150 mm, welding unstable screw hole, screw stainless steel plate, aluminum plate and composite steel pipe, aluminum plate air pipe surface without obvious pits, composite steel pipe surface without damage and other defects.
3. The air duct bite seam is tight, the width must be the same, there are no holes, half bite, and breakage defects. The longitudinal joint of straight pipe is staggered and unified to the outside surface of the air duct with parallel planes at both ends and concave and convex surfaces not more than 10mm. The connection between air duct and flange is the key, flanging is flat, width is not less than 6mm.
