For Jinan ventilation pipe processing, there will inevitably be problems. Here are two common problems, which can be seen from the angle of pipe inclination, elbow angle and pipe processing materials.
1. Incorrect pipe inclination and elbow angle
Performance: the folding angle is not straight; The two opposite planes of rectangular duct are not parallel to both ends; The bite is not strict; Diagonal lines are not equal.
Cause: The pipes are parallel in pairs, and the length and width of the opposite plate are not equal; The setting of sheet blanking and lofting is incorrect.
Impact: It will cause uneven force on the ventilation pipe, the installed pipe is not straight, the flange gasket is not firm, and the system leaks, resulting in the loss of air conditioning load and the shortening of service life.
Measures: During unfolding and blanking, the right angle of the plate shall be strictly limited, and the length, width and inspection diagonal of the plate shall be controlled within the allowable range; After blanking, the two plates in the opposite part of the pipe shall be overlapped to check the dimensional accuracy.
2. The pipe processing material does not meet the standard
Performance: the pipe surface sinks, the side protrudes outward, and the deformation is obvious; The surface of the plate is uneven, with uneven thickness, obvious indentation, crack, sand hole, scar and rust.
Cause: The material is unqualified and cannot meet the requirements for manufacturing air duct.
Impact: air duct leakage, air conditioning load increase, and air duct life and performance are affected during operation.
Measures: Before manufacturing pipes, it is necessary to check the factory certificate, material certificate, appearance thickness, etc. of materials to ensure the availability of materials.
