Setting of flame arrester differential pressure gauge on fuel gas pipeline
Thread Content
Set a flame arrester on the main fuel gas entering the heating furnace and the continuous lamp fuel gas. I would like to know if it is necessary to set a pressure difference gauge before and after the flame arrester?
I have never seen a flame arrester equipped with a differential pressure gauge~~If you are afraid of dirt and blockage, you can install a filter~~
Sinopec’s guidance on heating furnace chaining clearly stipulates: A pressure gauge must be installed before and after the flame arrester to determine whether the flame arrester is blocked. Moreover, a parallel flame arrester must be installed.
Please tell me, which standard does Sinopec follow for the setting of flame arresters in heating furnaces?
It is necessary to set a pressure difference gauge before and after the flame arrester to determine the blockage of the flame arrester.
This opinion only mentioned that a flame arrester should be installed, but it did not mention that a pressure gauge should be installed before and after the flame arrester, right?
Is this a standard? A guideline from Sinopec?
What must be set is usually a flame arrester with high pressure difference and interlocking to shut down the furnace.
