Regarding the strength calculation of air coolers
Thread Content
GB150 provides a clear calculation procedure for the strength assessment of the structure of plug-type air coolers. However, for types such as those with removable covers, only the calculation method for the thickness of the flange cover is outlined in NB47007; as for other tube box plates, it is specified that they should be calculated based on 150 flat covers. I’m not sure how to carry out this calculation
I remember it should be clearly stated in Appendix 150; though I haven’t calculated it in detail

There is a book titled \"Air Coolers\", which contains calculations for various types of tube boxes in air coolers; however, it needs to be studied in conjunction with the national standard 150
