Dear experts,
In our project for pressure vessels, moc- SA 516 gr.70 N, shell thickness 55mm (nace MR 0175). After doing PWHT, hardness measured and most of readings found in limit.
According to procedure vessels having more than 50mm thick hardness value shall not exceed more than 225 (brinell for p no. 1). But some values are 228,230,18 etc.. could we get expert advise to adress this dis-parity pl.
Thanks in advance,
Kumar.
