I have updated the topic again, now with the relative proportions.
Hopefully someone can give me the partial pressure of the hydrogen.
Thanks in advance.
An methanol (CH3OH) converter has the following operating conditions:
Pressure: 105 bar (g)
Temperature: 270°C
The gas mixture composition is:
CH4 = 12 vol %
CO = 0,74 Vol %
CO2 = 1,41 vol %
H2 = 80,33 vol %
Methanol gaseous +/- 5 vol%
N2 = 1,0 Vol%
Total 100,48 vol %
Can someone give me the...
Dear DekDee,
The burn through is probably induced by spacing between the plate and the pipe. Due to this the welding speed has been reduced and resulted in the burn through.
Regarding the heat input isn't a essential but a supplementary essential.
@ mk3223, what about the circumferential...
Dear DekDee,
The as welded composition is like 16Mo3 (P3) which is quite common for power plants. The medium is demineralized water / steam.
Furthermore the fillet weld has been qualified by a but weld (SA106 grade B to 16Mo3).
So the burn / melt through is covered by a valid PQR.
I don't see...
Gents,
I have a question about a fillet weld burn through (melt through).
We have welded a strip (5 mm thick 16Mo3) to a pipe (60,3 x 4 mm SA-210 grade A1)
During the visual inspection by our client, they discovered a burn through (only a few tenths)
The pipe is a part of a membrane panel...
