B31.1, 3, 9

[ElSid1]

Does anyone have a "quick sheet"/synopsis comparing B31.1, B31.3 and B31.9? I'm liiking for something like:

http://www.engineeringtoolbox.com/asme-b31-9-working-pressure-d_10.html

Working on wastewater treatment and EVERYTHING is specified B31.1. Contractor is pushing B31.9. As a plant, we are trying to explain why B31.3 is the correct standard. I need to do a presentation to the client "explaining" the differences (i.e. radiographic testing, treatment of pipe prior to welding, etc.)
Thanks

ElSid1,
This is from the Introduction of B31.3.

The ASME B31 Code for Pressure Piping consists of a number of individually published
Sections, each an American National Standard, under the direction of ASME Committee B31,
Code for Pressure Piping.
Rules for each Section reflect the kinds of piping installations considered during its development,
as follows:


B31.1 Power Piping: piping typically found in electric power generating stations, in industrial and institutional plants, geothermal heating systems, and central and district heating and cooling systems

B31.3 Process Piping: piping typically found in petroleum refineries; chemical, pharmaceutical,textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals

B31.9 Building Services Piping: piping typically found in industrial, institutional, commercial,and public buildings, and in multi-unit residences, which does not require the range of sizes, pressures, and temperatures covered in B31.1

Seems items 1 (B31.1) and items 3 (B31.9) would be classed as not applicable to your situation,
Regards,
Kiwi

B31.1's emphasis is on high pressure, high temperature piping - neither one of which you have.

Post this question in the Water Treatment and Distribution forum and you'll probably get some answers based on previous experience with waste water treatment plants.
