Is it reasonable to use austenitic stainless steel as the material for designing storage tanks in accordance with GB50341?
Thread Content
I have seen such drawings; the storage tanks are designed in accordance with GB50341, using 306L material. However, GB50341-4.2.2 does not specify the allowable stress values for austenitic stainless steels. I would like to ask the experts how to deal with this situation?
The material of the storage tank mentioned by the poster is 306L. Since GB50341-4.2.2 does not specify the allowable stress values for austenitic stainless steels, the design and manufacture should be carried out in accordance with Article 12 on vertical cylindrical storage tanks in JB/T4735-1997. The allowable stress values for stainless steels can be found in Table 4-2 on page 14 of the JB/T4735 standard.
There are still quite a number of stainless steel tanks in the food and pharmaceutical industries. However, their volume is generally relatively small. The standards for atmospheric pressure vessels can be referred to
It’s not very reasonable, as using the values from GB50341 for determining the minimum thickness of the tank wall and bottom is somewhat wasteful; API650 can be used as a reference
Agree with the person above; it is recommended to follow API650
Stainless steel storage tanks can be designed in accordance with SH3046 \"Design Code for Vertical Cylindrical Welded Steel Storage Tanks in the Petrochemical Industry\".
The calculation methods for seismic and wind loads specified in SH3046 are outdated; can this standard still be used for tank design? If the storage tank is relatively small, it is better to design it in accordance with JB/T4735.
For a storage tank with DN8000, Hw10M, a design pressure of 50 KPA and a design temperature of 80°, it is not very economical to use GB50341 for calculations; can JB/T 4735 be used instead?
Flat-bottom storage tanks are not covered by JB 4735, right? PS: 4735 has been replaced by NB/T 47003
