Introduction I have for many years wanted to compile some thoughts about piping design. As a young engineer, I was often confronted with a problem that was new to me. Older engineers and superiors would often advise me to “check the Corinth job,” or “see what we did five years ago on the XYZ project.” I would dig through stacks of files and dozens of drawings, only to find that the problems were not the same, or what they had imagined as an existing solution existed only in their failing memories. Nothing was on paper that could be applied to the problem at hand. I suppose this sort of thing applies not just to piping design, but to every other aspect of engineering as well. In any case, I would waste a lot of time looking for answers in the existing reference materials, only to discover that many texts were silent on the topic under investigation. I would then be forced to do a lot of research and draw my own conclusions.
