Rectangular boiler design
Rectangular boiler design
(OP)
I am designing a rectangular boiler from a flat plate of steel. The steel will be bent to form the rectanglar shell of the vessel. Heads will be added later. My question is:
What is the correct section of SECTION I should I use (PG-46 or PG-27) in detemining the minimum thickness reguired?

1.Use a finer grain steel. ie:516 Gr70
2.Make your bends across the grain. Make sure you use the proper radius.
3.Be careful on your stays. Number,diameter,material,full pen.weld,etc.

You might want to check ASME Section VIII Div 1 as there are certain circumstances where an electric steam generator may be constructed under those rules.

Thanks in advance for any info.

We purchase our SA-285C steel from a steel service center. Most of the time it is A-36 material that is recertified by an outside lab and tested to SA-285C specs. This is done by the sevice center and the cost is passed onto us in a higher cost per pound for the steel. Usually we pay about 4 cents/lb. more for SA-285C over SA-36. Depending on the amount of steel you need you can also order from a Mill (20 tons and up)
A starting place might be Ryerson Steel or CitiSteel.
Hope this helps!

Think you better review ALL of PG-10.
