We have inherited 2 Older Marley NC cooling towers. Previous owner was going to scrap them then changed their minds. But they had already removed the packing and disposed of it as well as half of the mist or drift eliminators. So My plight is these CT's are going to be used in a pilot plant that...
Gentlemen and Ladies,
This question has probably been answered in this forum before.
I am drafting exhibits for the QA manual in a new ASME CODE SHOP fabricating Section VIII vessels.
The Document lining out the procedure you want the PWHT company to follow. Temp, Ramp up sequence Hold Cool...
I have a 2"line with 10,000# of steam a 60 psig entering a 8" line that has 8,000# of 3 psi steam flowing in it in it. What pressure can I expect to see in the 8" line. A little above my head.
I have always performed this task but I am now asked to show what document or regulatory body requires that base line data be taken on piping and equipment installations. It may have been in the federal register. Any help will be appreciated
Performing fitness for service calculations on a 1950 vintage vessel. I need Max allowable stress as well as yield . Vessel operates at 250 degrees. In the day MDMT was not thought of so what would be the most like material today to calculate a MDMT too.
Good morning Gentlemen and Ladies. The problem is I have a 100K pph natural gas boiler that will only turn down 2 to 1. The problem stems from the fact that at the lower rates the pressure in the fire box/furnace area swings from +2.9 wc to -1.2 wc at 50K pph. At 40K pph the swing get worse +2...
Interesting issue is that while performing calculations on an ellipsoidal head on a vessel fabricated in 1947 using todays formulas it won't work according to ASME section VIII.
Is the formula used in 1947 different that that used today? I noted that the MAWP is based on a percentage of burst...
Designing a new system that has 15% water, 20% natural gas liquids and 65% hydrocarbon condensate in the stream.
I want to filter the entrained particulate matter to 20 micron.
Now if the inlet is lower than the outlet then the gas could be bled off at the outlet.
This would be done by...
