Hold at 150% designed pressure for how long?
If there is anything about the freelance trade that is universally true, it probably involves pressure and time in some way. That’s why we were very interested in an offer to edit and typeset a text book on pressure vessels. For those who haven’t heard of such a thing, a pressure vessel can be anything from an accumulator in a hydraulics system to a compressed air tank to a steam boiler. They all contain a fluid under pressure. Some systems can operate at very high pressures so there is an extra emphasis on finding and correcting errors. Errors can result in equipment beiing overpressurized: the result is an increased risk of failure which could possibly killing someone.
With a 20-page sample in hand, we worked up a proposal and sent it off. It brought back the good old days for Reese when he wrote repair procedures and personally performed repairs on steam boilers and other pressure vessels when he was in the US Navy. That experience gave him the practical and technical proficiency needed for a highly technical textbook like this one.
