Public Input No. 3-NFPA 67-2017 [ Section No. 1.4 ]

1.4 Applications.

Applications of this guide include the following:

(1) Process piping for which a hazard analysis has identified the potential for flammable mixtures

(2) Vapor recovery system piping

(3) Gas venting piping and manifolds

(4) Gas piping for water electrolysis and fuel cell systems

(5) Flare systems

(6) Fuel gas piping for which a hazard analysis has identified the potential for flammable mixtures

(7) Oxygen piping for which there is a potential for flammable gas or vapor entry

(8) Piping cleaned by flammable liquid solvents that can develop flammable mixtures

Statement of Problem and Substantiation for Public Input

The three additional applications represent a potential for flammable gas formation.

7.5.2

Analytical equations to calculate pipe wall strains due to detonations are given in Section 7.7. Criteria todetermine whether the calculated wall strains will produce permanent pipe deformation or pipe rupture aregiven in paragraph 7.7.1.4 and Section 7.7.3, respectively.


The section on Detonation Containment in Pipes should include a reference to the material in section 7.7 on pipe structural response equations and criteria for pipe permanent deformation and pipe rupture.
