Are there any specific standards for the design of vertical steel storage tanks?
Thread Content
I plan to build a nitrogen storage tank with a capacity of 50 cubic meters or 100 cubic meters, at a pressure of 1.8 MPa. Are there any specific standards for the nominal volume, nominal diameter, height, and height-to-diameter ratio of vertical storage tanks? Like spherical tanks have GB12337. I found a German standard, DIN28021, which contains fairly detailed regulations; no similar standard was found in China. The nominal diameter of pressure vessels is specified in the GB/T9019 standard. It seems that no specific standards have been found for the others.
Implementing the <Design Code for Vertical Cylindrical Welded Steel Oil Tanks GB50341-2003>
The Code for Design of Vertical Cylindrical Welded Steel Oil Tanks GB50341-2003 is applicable only to the design of vertical cylindrical welded steel oil tanks under normal pressure (including slight internal pressure). It can be designed in accordance with \"Steel Pressure Vessels for Petrochemical Industry\" SH/T3074-2007.
This is a typical gas storage tank; it’s designed in accordance with GB150 standards, so there’s no problem with that. As long as the calculation is correct, that’s fine
Calculated according to GB150; as for the geometric dimensions, the primary goal is to save material, and the secondary goal is to make it look better – that’s all that matters. But I seem to have seen somewhere the diameter and height corresponding to a certain volume, but it doesn’t seem to be standard! This post was last edited by chihongjun on 2009-3-20 11:55.]
GB50235, or the GB150-1998 Design Code for Steel Pressure Vessels can also be used. There are many design parameters inside. You can use it as a reference
GB150-1998 Design Manual for Steel Pressure Vessels
The \"Design Code for Vertical Cylindrical Welded Steel Oil Tanks\" – that’s right
It is absolutely not permissible to design it in accordance with the design specifications for vertical cylindrical welded steel oil tanks, GB50341-2003; otherwise accidents will occur. This is a pressure vessel. What is the temperature? The process conditions need to be clarified. Where does this nitrogen come from? Could low temperatures occur? Generally, there is a corresponding relationship between saturated vapor pressure and temperature. 1. I need to find out what the saturation temperature corresponds to for 8MPA nitrogen. This equipment is suitable for use as a vertical, skirt-supported container, as its volume is not large – only 50–100 M3. If the volume were larger, it would be more appropriate to use a spherical tank, which would help save material. As for the length-to-diameter ratio distribution for volumes of 50 to 100 cubic units, calculations based on integration suggest that a ratio of 1:1 is the most economical option; however, this also needs to take into account the actual site conditions, with the process design of the equipment being the key factor here. Generally, the length is greater than the diameter, as this helps save space; after all, land is more valuable.
Thank you all! The issues related to design standards and height-to-diameter ratio have been resolved. For questions regarding design calculations, please go to http://bbs.hcbbs.com/thread-425851-1-1.html to discuss them :)
How was the final height-to-diameter ratio determined by the poster?
