The 1994 is the last of the red ones and I still call it the Red Book.

I'm pretty sure '87 was Red. '91 and beyond is foggy, but I called it The Red Book till around the turn of the century :) -----Original Message----- From: Jeff Garrison [mailto:[email protected]] Sent: Thursday, June 06, 2013 7:28 AM To: [email protected] Subject: RE: required section modulus (it don't get no easier) Something else to remember / revise in your calculations is that the minimum Yield Strength of almost all steel pipe today is 30,000 psi, some going to 33 or 35k. The 15,000 used in the "red book" (how long since it's been red?) is quite out of date.
