Problems with natural gas hard-sealed check valves
Thread Content
I have a question regarding valves. I would like to ask those who have experience working with natural gas valves: when using H44H hard-sealed check valves for natural gas pipelines, is there any risk of sparks? Could an explosion occur due to metal-to-metal contact and the resulting sparks in these pipelines? Thank you; I hope those with practical experience can answer this question
This possibility of explosion is generally not taken into account; gas check valves are usually hard-sealed
Thank you. Is it because there is no oxygen in natural gas that it doesn’t explode?
The three elements of combustion: without air, there is no explosion
If both pressure and temperature are not very high, H44F can be used just fine
This usually doesn’t happen!
You’re right, but I just want to figure this out. Thank you
For natural gas check valves, it is recommended to use H44F type with PTFE face seals
Axial flow check valves are now commonly used in gas pipelines, especially at the outlets of pumps and compressors!
