NFPA 67 Guide on Explosion Protection for Gaseous Mixtures in Pipe Systems 2016 Edition This edition of NFPA 67, Guide on Explosion Protection for Gaseous Mixtures in Pipe Systems, was prepared by the Committee on Explosion

31、 Protection Systems. It was issued by the Standards Council on November 14, 2015, with an effective date of December 4, 2015, and supersedes all previous editions. This edition of NFPA 67 was approved as an American National Standard on December 4, 2015. Origin and Development of NFPA 67 In 1965, an

32、 NFPA Committee was appointed to develop standards for explosion protection systems. The standards were to include information on explosion prevention and mitigation in vessels, ducts, and buildings, focusing primarily on deagrations. During a meeting in 1997, the committee rst considered the subjec

33、t of protection against detonations in manifold pipe networks out of concern for the proliferation of vapor recovery systems at ammable liquid transfer stations. In 1999, the Standards Council approved the creation of a new document to address this issue, and the rst draft of NFPA 67 was presented i

34、n 2011. Following a period of public review and comment, NFPA 67, Guide on Explosion Protection for Gaseous Mixtures in Pipe Systems, was issued in 2013. The 2016 edition expands the section on detonation forces on pipes, provides additional guidance on the proper application of detonation arresters

35、, and provides references to address the design of piping systems that are outside the scope of the guide.EXPLOSION PROTECTION FOR GASEOUS MIXTURES IN PIPE SYSTEMS 67-2 2016 Edition Technical Committee on Explosion Protection Systems Larry D.
