Pipe Spool

Definition - What does Pipe Spool mean?

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.

Corrosionpedia explains Pipe Spool

Pipe spools, and by extension entire pipeline systems, are prone to corrosion and degradation. There are two common ways to protect pipelines against such occurrences:

  1. Applying a protective corrosion resistant coating, such as an epoxy coating, during the manufacturing process.
  2. Performing routine inspections with pipeline pigs to check for cracks and corrosion while the pipeline is in operation.

Pipe spools are fabricated using raw pipes and pipe fittings (flanges, elbows, tees, etc.) The raw pipes are cut to predetermined sizes that are compatible with the pipe fittings and other components.

The pipe spooling process is made up of two main sections:

  1. Roll fitting and welding
  2. Permanent position fitting and welding
