All vessel and attachments are required to design to -45 ºC For vessel support legs (18” beam), Ladder and Platform, there are no impact tested structural materials available. How to design to -45ºC? One thought is to design to very lower stress level, less than 40% allowable stress. Then...

I contacted to ASME secretary, the correct equation is L_R1= [sqrt(R_eff*t)]+W

Section II-D Table 5A shows P-No1 for SA-612 We are first time to use this table. Should assume this is a typographical error.

I think it is wrong. When I do the calculation, just use sqrt(Reff*t)+W Didn't talk to AI yet.

Is there any one has the experience of SA-612? For VIII-1 P-No is 10C But for VIII-2, P-No is 1 Any one can explain it?

grampi1, Thank you for your comments. The material is for the vessel of Slug Catcher. At beginning, customer designed the aluminum hot spry internal coating. Due to new findings with respect to the RFG gas composition, the internal thermal spray of aluminums coating is no longer required. But...

One of our customers wants the additional requirements for SA 516-70N materials. But I can not find any dealer or mill can offer it. 1. Are these SSC and HIC test method suitable for SA 516-70N? 2. Are these requirements difficult to meet for SA 516-70N? 3. Is there any one can provide some test...
