(1) Use
        Control charts are a method that uses statistical principles. This principle is often used in quality control work to perform process capability analysis and process analysis.
        (two) control principle
        When the project implementation process is in a normal state, the project's operational activities are stable, or a process that operates according to standardization. At this time, most of the quality control points should be within a certain small boundary (this boundary usually adopts ±3 times standard deviation, if the requirement is low, it can be enlarged), or the arrangement has a regularity. The higher the quality level, the less likely it is that the control boundary or the alignment is defective; and once the point exceeds the control limit or the arrangement is defective, it can be considered that the good condition and standard operating conditions for maintaining the normal operation of the project are highly likely to have been damage. Therefore, it is possible to control the quality through the control chart reflecting the quality state, that is, to measure the quality point in the process, and when an abnormality is found, it is possible to further observe, investigate, clarify the cause of the abnormality, and take measures to eliminate the abnormal factor; Conversely, if the control point is normal or normal after the measure, the effect of good control can be obtained.

Downpipe Roll Forming Machine

A downpipe roll forming machine, has been designed for making square or round (circle or rectangular) rainwater pipes.

A downspout has many different names as, waterspout, downpipe, drain spout, and roof drain pipe etc. According to wiki, the downspouts are applied mainly as below:

In the very beginning the downspouts are made of plastic, then PVC; due to the advancement of roll forming technology, people turn to roll formed pipes, and in mordern times, most of the downspouts or rainspouts have been produced from pre-painted steel, galvanized steel,aluminum or cooper.
