Yes, true, the corrugations can cause flow friction. Normally we use our hose that is certified for O2 and smooth on the inside. Three people were injured, luckily they are all recovered.
Thank you very much! Indeed your text is very helpful. I think you are right about adiabatic compression and impingement velocity unison. These two phenomena are very similar and can happen simultaneously. The hose was made from rubber, but corrugated, so traces of oil have been carried over...
well, we have a skid supplying O2, N2 and LPG to the blast furnace. The oxygen was connected with a hose (1-1/4 in) to an oxygen line (2 in). We used client's hose , probably not purged and perhaps also not certified for oxygen (we can;t trace back the cause of explosion). Anyhow, upon start up...
hi
Can someone tell me whether the pressure level is critical for adiabatic compression of oxygen in the pipe to happen? An oxygen hose exploded at the client site, in which the oxygen supply pressure from the header directly to the hose at the moment of explosion was about 6barg. Pressure range...
