Air is very important to people's life. We can't live without air. Oxygen in the air is also the basic element to maintain people's lives. Therefore, indoor ventilation should always be maintained to meet people's demand for oxygen. This is also the influence of ventilation pipe processing on people's life. But what are the quality problems in the process of processing? Let's follow Shandong ventilation pipe processing manufacturers to understand it.
1. Processing data not up to standard:
① Performance: the surface of the plate is not smooth, the thickness is not uniform, there are significant indentation, cracks, sand holes and corrosion; the plane of the ventilation pipe is sinking, and the side is facing outward, there is significant deformation.
② Impact: air leakage in ventilation duct, air conditioning load increase, and air life and performance are affected.
③ Cause: the data is not qualified, and the requirement of manufacturing ventilation duct is not satisfied.
④ Methods: before using the ventilation pipe processing equipment to manufacture the ventilation pipe, check the factory certificate, quality certificate and appearance thickness of the materials to ensure that the materials are available.

2. Shandong ventilation pipe warping angle and elbow are forbidden
① Performance: two relative planes and two ends of rectangular ventilation duct are not parallel; the angle is not straight; the diagonal is not equal; the bite is not tight.
② Influence: it will make the ventilation pipe connection stress uneven, the ventilation pipe after the device is not straight, the flange gasket is not tight, the system air leakage, resulting in air conditioning load loss, and shorten the service life.
③ Causes: the setting out of plate cutting is strictly forbidden; the ventilation pipes are parallel, and the length and width of plate on opposite side are not equal.
④ Methods: when opening the blanking, the angle of the sheet should be strictly square, and the length, width and diagonal of each sheet should be checked, so that their deviation can be controlled within the allowable range; after blanking, the two sheets on the opposite side of the ventilation pipe should be overlapped to check the size accuracy.
