Pipe Fabrication Institute (PFI)

IHS Markit is your source for PFI standards and publications.

The Pipe Fabrication Institute (PFI) was formed in 1913. It is one of the oldest and most respected industry associations in the United States. The PFI exists solely for the purpose of ensuring a level of quality in the pipe fabrication industry that is without compromise.

Over the years PFI has fulfilled its charter by:

  • Initiating engineering, studies and research
  • Proposing and maintaining suitable standards and technical bulletins.
  • Organizing meetings, technical exchanges and presentations among members pertaining to materials and products, techniques of fabrication and operation, methods of examination and testing and other topics.

IHS Markit is the source for all standards and technical bulletins of the Pipe Fabrication Institute. These publications cover topics such as: Internal machining and solid machined backing rings for circumferential butt welds; Dimensioning pipe assemblies; Fabricating tolerances; Hydrostatic testing of fabricated pipe; Permanent marking on piping materials; Wall thickness measurement by ultrasonic examination; Color coding of piping materials; Pipe bending tolerances; Abrasive blast cleaning of ferritic piping materials; Tool calibration; Pressure-temperature ratings of seamless pipe used in power plant piping systems; Reinforcement tables for steel pipe, pipe fabricator, and quality control.
