Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents" Drafting. This document replaces GB 5908-2005 "Flame arresters for petroleum storage tanks" and GB/T 13347-2010 "Flame arresters for petroleum gas pipelines". Based on GB 5908-2005, it integrates the contents of GB/T 13347-2010. Compared with the previous version, in addition to structural adjustments and editorial changes, the main technical changes are as follows. a) Add the terms and definitions of “tube end flame arrester”, “short-term combustion”, “unstable detonation” and “overdrive detonation” (see Chapter 3); b) The terms and definitions of “fire retardant core”, “limited fire retardant speed” and “safe fire retardant speed” have been deleted (see Chapter 3 of GB 5908-2005). and Chapter 3 of GB/T 13347-2010); c) Changed the terms “flame arrester”, “pipeline flame arrester”, “deflagration flame arrester”, “detonation flame arrester”, “maximum test safety clearance”, “stable The terms and definitions of "stable combustion", "stable detonation" and "maximum working pressure of medium" (see Chapter 3, Chapter 3 of GB 5908-2005) and Chapter 3 of GB/T 13347-2010); d) The classification of flame arresters has been changed (see Chapter 4, Chapter 5 of GB 5908-2005 and Chapter 5 of GB/T 13347-2010); e) The model number has been changed (see Chapter 5, Chapter 4 of GB 5908-2005 and Chapter 4 of GB/T 13347-2010); f) The requirements and corresponding test methods for the flame arrester at the pipe end for deflagration resistance have been changed (see 6.6.1, 7.7, 6.5, 7.6); g) Changed the requirements and corresponding test methods for the deflagration resistance and detonation resistance of pipeline flame arresters (see 6.6.2, 6.6.3, 7.8, 7.9, 6.6 and 7.7 of GB/T 13347-2010); h) Added the requirements for short-time combustion resistance and the corresponding test methods (see 6.7.1, 7.10.1); i) The requirements for pressure loss and ventilation volume and the corresponding test methods have been changed (see 6.9, 7.11, 6.8, 7.8, GB/T 13347-2010, 6.9, 7.9); j) Added requirements for electrostatic jumper wires and corresponding test methods (see 6.10 and 7.2); k) Added the requirements for “flame arrester test gas” (see Appendix B).
