Cold traps — steam traps that no longer drain condensate — are often ignored in lieu of less-critical leaking traps, until a catastrophic event, such as a plant shutdown or personal injury, occurs. Use historical data to accurately estimate the annual cost of these cold traps to justify their swift repair.
Pipes and equipment that are not properly supported will be subject to stress, vibration, or other problems, This can cause leaks, or even a complete collapse of piping or equipment. But, problems with inadequate support of piping and other...
