A 3/4" Class 6000 threaded forged fitting is shown to have an equivalent wall thickness of a 3/4" XXS CS pipe per ASME B16.11. If you were to calculate the MAWP using SA-106 material, an 1/8" CA, both a taper allowance and a thread allowance, you would end up with a MAWP close to 4500 psig at...
Has anyone had to create a 22" lap joint flange for a manway in compress that has the lap joint extending to the OD of the flange? Compress doesn't appear to have the option to include a slot for the bolt holes in the lap joint when you are editing the Appendix 2 flange. Has anyone come across...
Thank you Latexman for the clarification. You are correct and I apologize for the confusion.
Thank you MJCronin for the reference links. I will review the information. The existing piping downstream of the valve is currently P91 and if we were to increase the line size we would replace the...
quark, will you please explain what you mean by "your steam is already wet downstream"?
Maybe i didn't explain this well in my original post, but what I'm trying to do is increase the mass flow rate through the valve. The system is existing and since my mass flow is increased now my velocity is...
I currently have a project I'm working on which is an existing power plant designed to asme section 1 that has some letdown valves that have desuperheating capabilities. The pressure on the high side is 1500 psig and the low side is 425 psig. Boiler feed water is introduced within the valve to...
