Pipe spools are the pre-build parts of a piping system. Pipes， flanges， and fittings are called pipe spools and they are produced before they are used in the piping system. Pipe spools are pre-shaped to make easier assemble using hoists， gauges and other tools for joining the parts.
A pipe spool refers to a section of a piping system that is prefabricated as smaller segments with flanges and fittings. Pipe spools are often prone to corrosion due to their exposure to the elements， water and other natural electrolytes. Adequate preventative and restorative monitoring must be implemented when maintaining pipe spool applications.
