Introduction:

Ihave 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. Many phone calls later, I was finally able to lay my hands on a copy of PFI Standard ES-5, Cleaning of Fabricated Piping. This was a three-page document published by the Pipe Fabrication Institute. At least now I had a starting point and was able to apply this standard to the system that was causing so much heartburn among my managers. Back in 1984, one had to rely on picking up a scent, persistence, and lots of phone calls and trips to the library. Now that we have the Internet, the playing field has been leveled, although a quick Internet search of “pipe cleanliness standards” proves that today the process is still no picnic. There are many excellent reference materials available. Some of these are referenced in this manual, and no serious student of piping should be without the Piping Handbook by Nayyar, or earlier editions by Crocker and King. This is not a scholarly manual. I have tried to organize it in a logical manner and make the information readable and easy to access. The reader will forgive me for stating certain opinions (which should be obvious in the text, and not to be confused with facts)
