Hi Efrin,
I suggest that you look at ASME/ANSI B31.3 Process Piping Code, which has a section on high pressure piping (above class 2500). There are some Code limitations on fabrication methods used in high pressure piping that you need to be aware of.
Be careful about socket weld fittings...
Gentlemen,
OOPS sorry, I missed the point. Yes class 150 is still class 150. The P/T rating is what it is and the Code simply adds some further restrictions and limitations.
TBP's report on information from the Piping Handbook is good. I agree with TBP's "read" on what the...
It will depend upon the piping Code that the juridiction requires you to use, not on the fitting Standard. For example, if it is a B31.1 Power Piping application:
From ANSI / ASME B31.1 Power Piping Code
124.5 Malleable Iron
Certain types of malleable iron have low ductility characteristics...
Hello BTD,
Actually, the biggest difference is that B31.1 allowable stresses are based upon a factor of safety of 4 while B31.3 allowable stresses are based upon a factor of safety of 3 (if we assume we are below creep ranges for both).
B31.1 focuses upon a very narrow application - power...
Hi George,
First, I would hope that you are a mechanical or structural engineer. If so you will have a solid background in the analysis of irregular space frames (beam theory).
The quickest way to get a good grasp of the topic as a start is to attend a well designed professional seminar...
I would recommend that you look into getting a copy of a recently issued Welding Research Council document:
Title: Guidelines for the Design and Installation of Pump Piping Systems.
V. A. Carucci and J. A. Payne
Welding Research Council Bulletin 449
This is a guide to designing piping systems...
Hello,
I think that most experienced piping designers will agree that the best pipe joining method to use to assure long life in steam piping is properly fabricated B16.9 welding fittings. There is a temptation to use threaded joints or socket weld joint with small diameter piping which are...
Hello,
On the subject of books, I believe that the best available contemporary piping design book is "Practical Guide to ASME B31.3 Process Piping", by G.E. Woods and R.B. Baguley (published by CASTI Publishing Company, 14820 29th Street Edmonton, Alberta, Canada, T5Y 2B1, Canada...
