Design of stainless steel storage tanks
Thread Content
When dealing with the design of storage tanks made of stainless steel, currently only JB4735 and SH3046 cover stainless steel materials, while the latest standard GB50341 does not include such materials. As a result, in the design process two standards have to be applied simultaneously: the allowable stress is determined according to SH3046, while the calculations are carried out based on GB50341. Overall, this approach seems inappropriate, especially since there is inconsistency when it comes to the minimum nominal thickness. GB50341 is essentially a copy of API650, yet API650 does include information on stainless steel materials, including appendices related to storage tanks made of stainless steel. The organization responsible for drafting GB50341 is the Petroleum Processing Institute, and the title of the standard refers to oil tanks; however, it is also stated that it can be used as a reference for petrochemical products as well. It’s unclear why they didn’t consider all aspects when drafting this standard. Moreover, for storage tanks involving high or extremely high levels of hazard, there are no standards at all to follow!
Yes, the standards for large storage tanks are a bit chaotic:lol
The standards for designing large tanks domestically are rather chaotic; this is the current situation. The original poster can search for posts on related topics – perhaps that will help to clarify things a bit.!
In my opinion, there is currently a problem in China regarding incomplete and inadequate standards for storage tanks, and it is likely that most of the contents of these domestic standards are based on API650.
Many foreign standards are worth learning from.
The standard GB50341 was developed by the Pipeline Research Institute; they have extensive experience with crude oil and various refined oils, but lack expertise in chemical products. SH3046 is actually a very good standard for tank design. Since GB50341 exists already, it makes things more complicated in many cases. Therefore, it is recommended that stainless steel tanks use the 3046 standard.
It is normal for Chinese standards to be copied from an API; what is abnormal is when the same API is used to produce N different Chinese design standards.
The main summing industries and **most of the standards in use are not unified
Are there any designs for fiberglass storage tanks?
Section 4.1.3 of GB50341 stipulates that: \"Materials must comply with the provisions of the latest versions of the standards listed in this code. Materials produced in accordance with other domestic standards may also be used, provided that they possess superior performance and meet the requirements of this code, and have been approved by the relevant authorities.\" ” That is, this specification is generally applicable to carbon steel and low-alloy steel. If the material is stainless steel, it is recommended to design in accordance with JB/T4735 and SH3046. The maximum pressure limit for SH3046 is higher than that of JB/T4736, and I personally believe that SH3046 is better formulated than JB/T4736; therefore, SH3046 is the preferred choice. Of course, the requirements of the project also need to be taken into account.
:)I’m a beginner; I tried to look up the manufacturing process for stainless steel storage tanks, but couldn’t find any information
