I have a condensor that will condense steam connected to a process flash vessel. I am looking for help sizing a vacuum pump to pull a vacuum on the condensor to condense the flash steam at 25" hg. Would like to know of any references to be able to help me size a vaccum pump for this...
Thanks Steven,
This is what I thought and since I have not experienced this I am hesitant to proceed. How did you resolve the blowback in your experience. Did you shorten the runs and go vertical? Did you run all lines independently?
Everytime I try to apply B31.1 Apprendix II Rules for PSV installation it always seems my f(Lmax/D) values are off the Chart II-1. I am looking for some discussions on this analysis. I do not have access to the original Keenan and Kaye 1948 Gas Tabels and do not know if values for f(Lmax/D)...
Does anyone know of a manufacturer who has Canadian Registration Numbers for their PVC and/or CPVC fittings? I spoke to IPEX and Spears and have been told that they do not have CRNs for their fittings. IPEX said that they were in the process but the project has been put on hold. Please let me...
Metengr,
Thanks again for the reply. I am going to limit the design temperature to 1000F in agreement.
Do you know what is the difference in the B8M class 1 and class 2 material that would allow class 1 material to be permitted over 1200F? Class 2 has a higher minumum yield 50 ksi vs 30 ksi...
Metengr,
Thanks for the reply. I forgot to mention that I was looking for data from 1050F to 1200F. For this material no values are presented. Sorry. I have a B16.5 flange application where I want to use this material and the application is for a Class 600 application and only design stress...
I am looking for published information for the following A193 B8M Class 2 Bolting Material:
- Average stress for creep rate of 0.01% per 1,000 hrs
- Average stress for rupture at end of 10,000 hrs
- Minimum stress for at the end of 100,000 hrs
This is for determining design stress values per...
