In addition, Piping designed according to B31.3 has less lifetime than
B31.1 due to lower F.S., and the reliability of piping under B31.1 should be higher than
B31.3.
I believe that there are, at least, two resources. One is ASHRAE HANDBOOK, and other is one North Amercia Valve Vendor's handbook. As I am out of home country for the business, sorry for no further detailed information available.
Metengr, many thanks from Indonesia!
As I said in my original post, this is an unintelligent disputation, and it is occurred in a non-English country. From 2004 Edition, I don't know what appeared in other editions, the declaration of "...In Contact With Furnace Gases > 850°F (455°C)" is broken...
Dear Metengr, I agreed with your opinion 100%, as I said in my question. However, what I need is a supporting document. Do you have it? I guess, some out-of-date code might have different Table PW-11 which was the temperatures in the same line of ...Furnace Gases. Anyway, Thanks for your reply.
I am working with an Indonesian local contractor and there is an unintelligent disputation here and now regarding Table PW11. They insist that the temperature mentioned in the top of the table, 455 Deg C, is the fluid service temperature even I had indicated there is no such water temperature...
I WOULD LIKE TO RECOMMEND TO BUY ASTM D 6439, STANDARD GUIDE FOR CLEANING, FLUSHING, AND PURIFICATION OF STEAM, GAS, AND HYDROELECTRIC TURBINE LUBRICATION SYSTEMS, 1999 EDITION, RATHER THAN ASME LOS-4C1 IN 1971.
For Tee: you can find EQUIVALENT LENGTH from various papers, text books, manuals, and handbooks. There are three types of tee, and the EQUIVALENT LENGTH relationships among them are:
Straight Thro Tee : Flow Out Thro Branch : Flow In From Branch = 1 : 3 : 4.35.
