GB50341 provides guidelines for determining thickness, but not for width. How is width generally determined? Please give me some patient guidance, seniors. Thank you! !
It mentions some things here; go take a look... http://bbs.hcbbs.com/viewthread.php?tid=256517
The width and length are determined based on the steel to be produced, and standard plates should be used as much as possible.
Use the standard version, but the minimum length must be no less than 2 meters, and the width must be less than 1 meter
Based on the requirements for processing and manufacturing, as well as the need to reduce the amount of machining and welding defects, the following two points can be considered: 1. Try to use standard sheet sizes, which can reduce the amount of cutting and improve material utilization； 2. Try to use steel plates with a wider width, as this reduces the amount of welding required, lowers the risk of human-induced welding defects, and also decreases the amount of inspection needed, thus cutting costs ；

The thicknesses of the bottom and wall plates of these storage tanks are specified in GB50341; this standard was developed with the involvement of the Sixth Research Institute for Chemical Engineering. It’s not clear whether there are any updated versions available. As for the width and length, these are determined based on the height of the tank – it’s determined what is the most reasonable number of sections to divide it into, and then those sections are combined appropriately. It’s not possible to leave a section at the bottom that needs to be cut using acetylene; therefore, the width is usually chosen to correspond to standard sheet sizes, such as 1.5M, 1.8M, or 2M. The length, on the other hand, is calculated taking into account transportation constraints and the diameter of the tank, and it’s generally determined by the installation team.
Based on the tank size, a layout diagram is created using the standard dimensions of the steel plates. The use of minimal consumables and welds, etc., is considered reasonable.
Depending on the order volume, large plates should be used as much as possible to reduce welds.
A reasonable selection is made based on calculations, the supplier’s resources, the amount of welding work, and other factors.
