Edwards statement...

"Errors in our field tend to show up more as maintenance issues - leaking flanges, worn pump seals, etc. But, with the the nature of the system, the client project manager isn't the same guy who has to maintain the plant down the line and isn't necessarily interested in spending money now (stress review) that will payoff later (lower maintenance cost) because those hours are just a cost in his budget. "

In my experience is right on target! I have been in situations where I could say with confidence that the reason his pumps needed seals changed out every 6 months were due to them being badly overloaded. The owner said he had money in his budget for the pump repairs but had no money for my work. Therefore he kept fixing the pumps despite the fact that my meager salary and refit was far less than 2 pump rebuilds....

The other thing that happens when the pipe itself breaks is that it must have been fabricated poorly...
