New issues in tank design, seeking advice
Thread Content
18M3 tank: medium – hydrogen + NaOH solution; operating pressure at atmospheric level; design temperature of 100 degrees. Material used: SUS310S. I need help – which standards should be referred to for the SUS310S material? What is the allowable stress under these design conditions? I’ve searched on Baidu but couldn’t find any answers. . . .
0Cr25Ni20 should be referred to
Using this material seems a bit too luxurious
0Cr25Ni20=SUS310S=310S – doesn’t anyone know this? What standard should be referred to, and what is the allowable stress?
According to the current GB150 standard, it should be 520/3=173MPa
Reply to 5# zrm0806: Which page and which provision exactly?
In China, it is equivalent to 0Cr25Ni20; the allowable stress is 520/3, and the safety factor is 170
The relevant strength values are obtained from GB/T4237 or the upcoming GB24511, and then, by applying the safety factor specified in GB150 (or the new code), the resulting value is 173 – is that correct?
The basis is the calculation of allowable stress, which is generally determined based on the selection of the safety factor per GB150.
