Piping Systems Manual
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. An example of this was when I was responsible for the start-up of a hot oil calender system, circa 1984. The mill engineers and project managers were concerned over the cleanliness of the piping. My initial reaction was that someone should be watching
what the contractors were doing as they fabricated and hung the pipe to ensure that the pipe remained clean. And although this seems to be a reasonable approach, it would not have assisted in this particular case. Nor is it common to bird-dog the fitters to ensure that hard hats, wrenches, 2 x 4’s, etc. don’t get left inside pipes.
Cleanliness of piping is not often addressed in the reference books. While there are Standards for the cleanliness of hydraulic piping and piping found in the Pharmaceutical and food and beverage industries, there was not a lot to choose from in the general arena of industrial service piping.
