One of the greatest's books available I already found in 2001 as a photocopy. I lost it, bought it new in a store, it got stolen... And I bought it again!
This book, first published in 1973(!) but still current is one of the greatest works ever written for anyone who is new in plant construction.
It gives a great overview about all the processes and disciplines involved in plant construction and features a section "Tables" for piping and Tube size comparison and a glossary index.
Although costly it is worth every Euro spend on it and I highly recommend it!
(and no, I do not get any money by saying this..)
