Analysis on model selection of tank seal of dodecafluoro-2-methylpentan-3-one
fire extinguishing agent

Abstract

Abstract:

The compatibility, causticity problems of fire extinguishing equipment tank for dodecafluoro- 2- methylpentan- 3-one fire extinguishing agent during the engineering practice were introduced. By immersion test, methods of weighting,drainage, and visual inspection were used to analyze the compatibility of 6 kinds of O type seal rings and the fire extinguishing agent, as well as the causticity of the agent to 6 kinds of metallic materials. The suitable nonmetallic and metallic materials for the sealing element were verified, to provide reference for the model selection of tank seal of dodecafluoro- 2-methylpentan- 3-one fire extinguishing agent.

Key words: dodecafluoro- 2- methylpentan- 3- one, fire extinguishing agent, sealing element, causticity
