Let’s discuss what the standard SH/T3408-B for this pipe fitting means
SH/T3408-B is a fitting standard for China’s petrochemical industry; “SH” denotes the Petroleum and Chemical Industry sector, “T” indicates that it is a recommended standard, the number 3408 is the standard’s identifier, and “B” represents the version of this standard. .
Where can I find the standard SH/T3408-B? I could only find SH/T3408. Could you share it with me?
The 2022 version is the 3rd revision; the 2012 version is the 2nd revision. The 1996 version represented the 1st revision, while it was first released in 1989. Which version does Version B refer to?

I’ve also looked up the English description you mentioned earlier; it seems to state that it is necessary to meet the design and calculation requirements for fittings as specified in Appendix B of GB/T12459. SH/T3408, on the other hand, relates to the manufacturing and acceptance requirements for fittings. I’m still not quite clear about the purpose of indicating this on the schematic diagram. When placing an order for fittings, is it sufficient to ensure that they meet the design and calculation requirements outlined in Appendix B of GB/T12459, or should the standard to be followed be specified as SH/T3408-B when placing the order?
sh/t3408 does not have sizes in series B; it is recommended to ask the design institute directly.
The representative from the design institute is working on the project, and they said they don’t know either. . . :L
Sigh, the design representative is retiring soon; it’s hard to put into words
There is an idea for reference only: in GB/T12459, there is an Appendix B section that specifies the contents of the design calculations for pipe fittings. “This appendix specifies the design and calculation methods for the minimum wall thickness of fittings that meet the corresponding structural parameter standards. The measured wall thickness at the corresponding sections of the finished pipe fittings shall not be less than the minimum wall thickness determined in this appendix. In the training materials for pressure pipelines, the instructor included such a sentence on the slides at that time. So, can it be inferred that the designers intended to indicate that drying should be carried out in accordance with Appendix B of 3408? But I checked, and there is no Appendix B in 3048. It might be trying to follow the approach used in 12459.
