There is no agreement to adhere to any PFI Standard and their use by anyone is entirely voluntary. Copyright by PIPE FABRICATION INSTITUTE A current index of the latest revised ES Standards, Technical Bulletins and Safety Training Guideline is available from the Pipe Fabrication Institute. PFI Safety Training Guideline, Standards and Technical Bulletins are published to serve proven needs of the pipe fabricating industry at the design level and in actual shop operations. Hence, such needs are continually considered and reviewed by the Engineering Committee of the Pipe Fabrication Institute to provide recommended procedures, which have been demonstrated by collective experiences to fulfill requirements in a manner for Code compliance. However, as the PFI Standards are for minimum requirements the designer or fabricator always has the option of specifying supplementary conditions in the form of requirements beyond the scope of the PFI publications.
