Dear Group Members, I have following query related to subject post, Dear Group Members, I have following query related to subject post Design Code : ASME Sec.VIII Div.1 Design Pre : 42 bar Design Temp : 85 Deg C Pressure rating : 300#, ASME B16.47 Series A Equipment : 38” Blind Flange...

Thanks for reply SnTman and ricklts. In both case we are as of now doing "design flange" to suit dimension as per standard flange to match with piping. However as expected no. of bolts are exceeding. If required to solve this we may need to give piping counter flange along with equipment nozzle...

Dear Group Members, 1.I am not able to find suitable material in ASME B16.5 for UNS 41000 (13%Cr). Is this material not listed under B16.5? What are the alternative material can be used? Or We need to go for design nozzle flanges? 2. API 6A flange for 10000# Rating We are designing equipment...

Dear group members, I am little confused about following question on external bolting selection for girth flange (w.r.t to flange material / sour service / temperature / Allowable stress and Flange design) 1.Currently we are using SA 193 B6 bolt (13%Cr S41000) for SA 182 Gr.F6a (13%Cr S41000)...

Thanks for reply. Why Part - 3 of ISO 15156-3 does not contain any information on acceptable bolting material like Part - 2 specifies B7M and L7M?Is there any reason behind it? CoryPad, I understand your explanation is based on the Table No.A.23 of the ISO 15156-3. I found no hardness value...

Dear Group Members, I am working on Heat Exchanger which is an electric heater. Design details are as below. Material of shell side is 13%Cr. SA - 336 Gr.F6 Service is high pressure CO2 Service Design Pressure = 320 Barg Design Temp = 85 / -20 °C Equipment is under sour service and NACE...

Dear Group Members, I am working on electric heater material of construction is 13%Cr. Service is high pressure CO2 Service Design Pressure = 320 Barg Design Temp = 85 / -20 °C Equipment is under sour service and NACE MR0175 is applicable. Can I use SA-193 Gr.B6 for the flange bolting (Non...
