Generally speaking, the duration of the "exhalation" of the q235 q235b welded rectangular tube is longer than that of the "inhalation" of the q235 q235b welded rectangular tube every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the q235 q235b welded rectangular tube location, open area of the q235 q235b welded rectangular tube, atmospheric pressure, filling degree of q235 q235b welded rectangular tube, etc. When the q235 q235b welded rectangular tube is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.
