pipe branches

[canman]

I need to calculate reinforcement of the branch connections per B31; does anybody know good freeware for that? Any help is welcome.
Thanks.

The branch reinforcement is based on compensating for displaced area of pipe wall. The calculation process is fairly straighforward. For a single branch you can do it manually. For a set of calculations I wrote up a simple spreadsheet.

 

Hello,

Look at Appendix "H" of B31.3. It is a "primer" for understanding the area replacement method.

Ben Nottingham's Piping Office Suite is a set of ExCel spread sheets that will help with many of the B31 calculations. Branch connection calcs are included. There ain't no such thing as a free lunch. More often (if you are lucky) you will receive justthe value you pay for.

Best regards, John.
