Photo Gallery A1: Pipe Failures
Many early occurring and often obvious signs of a corrosion or pipe weakness problem are ignored up until the moment that a failure occurs. At that instant priorities change, with – the larger the failure, the greater the level of panic. Most piping failures, at least initially, are small. They may be in the form of a slow drip at a thread or ERW weld seam, a weeping pinhole at copper pipe, or some wet insulation. Ironically, the greater the level of pitting within a piping system, the more likely its deepest penetration will produce the “tell-tale” warning indication that a larger failure event is on the way. Low and extremely uniform wall loss occurring over decades, on the other hand, may produce a substantially larger failure with no prior notice whatsoever.
Worst events are always total pipe separation resulting in catastrophic failure and million dollar losses. Fortunately, most piping failures provide an advance warning for those who are observant.
