People may be interested to know that the book Design of Piping Systems by M.W. Kellog has just been reprinted and is available through amazon for about 35USD.

Unless it has been seriously edited, it is well out of date with respect to anything in currect Codes. It's still a venerable source of information though.

No, It has not been updated, just reprinted, but still worth having......

Thanks for the info, sounds like a valuable book to have.
