  * Delivery of fluids, either gaseous or liquid, in a process plant from one point to another point in the process
  * Delivery of bulk solids, in a food or process plant from one point to another point in the process
  * The construction of high pressure storage vessels (large pressure vessels are constructed from plate, not pipe owing to their wall thickness and size).
  Additionally, pipes are used for many purposes that do not involve conveying fluid. Handrails, scaffolding, and support structures are often constructed from structural pipes, especially in an industrial environment.
