Testing of Flame Screens and Flame Arresters as Devices Designed to Prevent the Passage of Flame (DPPF) into Tanks Containing Flammable Atmospheres According to an IMO Standard.

摘要

Devices to Prevent the Passage of Flame (DPPF) include flame arresters, flame screens and pressure/vacuum valves which are used in venting systems on storage tanks and tanker vessels transporting flammable or combustible liquids. DPPFs are intended to prevent the propagation of flame into enclosed spaces containing explosive vapors/air mixtures. This report describes flashback and endurance burn tests to determine compliance of DPPFs to International Maritime Organization (IMO) Standard, MSC/Circ. 373, 'Standards for the Design, Testing and Locating of Devices to Prevent the Passage of Flame into Cargo Tanks in Tankers.' This report presents data of flashback and endurance burn tests conducted on four (4) flame screen arrangements and ten (10) arresters. Keywords: Arresters, DPPFs, Endurance burn, Flammable, Flame arresters, Flame screens, Flashback, Hexane/air, Ignition, Tankers, Pressure/vacuum valves. (JES)
