@ Patricia Lougheed,
yes this is the same question , somebody from there suggests me to ask in this forum. He said that I might get the better response here..
Thanks
@caracasec,
If changing the seal plan is one of the solution, which one is more appropriate plan 21 or plan 23?

Dear Floor,
I just have submitted the related attachments,
they are :
1. mechanical seal drawing
2. sectional drawing of mechanical seal + material data sheet
Kindly need your advices please,

Dear Floor,
Currently in our operational area, we are facing mechanical seal leakage problem on our BFWP. Even though we are using a treated water which regularly monitored for its quality, the leakage is still often occured.
The feedwater pump is horizontal multisatage pumps with a...
Actually, I have submitted also this question to that group and uniquely I just have the responds from all of you guys.
The feedwater pump is horizontal multisatage pumps with a horizontally split casing. A constant speed 4160 HP electric motor drives tat pump. The suction piping of the pump...
Dear Floor,
In our operational area here, we have numbers of pumps serving the boiler. The capacity is quite big. Currently we are facing leaks which oftenly occured in our pumps. Just for the information, we are using the treated water, which is periodically observed and monitored.
What I...
Dear all,
So, if I have 11 years old HRSG with the operating condition : 700 PSIG @ 500 F.
With the MAWP of the whole HRSG is 1500 PSIG,and the water that we have is 140F. And the PSV working pressure is 1050 PSIG
At what pressure should I do the hydrostatic test?
Thank You
OK.
so then,
when I'm gonna use this warm water during the hydrotest, will this warm water effect the integrity of the boiler ?
should I compromise it by reducing hydro test pressure due to this water temperature? if yes, what code & standard I should use?
Thanks
Dear Floor,
For this hydrotest ,
a. is it true that the water temperature should be around 70-120 Fahrenheit?
b. in here our demin water temperature is 150 F (which is over the recommended temperature range), please advise me what kind of mitigation plan that I need to do to overcome this...
Dear Floor,
I'm also looking for any international reference that can be used to develop the standard operating procedure for hydrostatic test.
This hydrotest is the requirement from our national board in here to get the certification.
Please kindly need your advice.
Thank You
@ davefitz & rmw
correction : the steam header should be larger.
thanks for your consideration, this HRSG has evaporator 1, evaporator 2 and the economizer. Obviously each of them has different stamping pressure.
@ floor :
I've heard about NBIC code, is it applicable on this case?
Dear Floor,
Here in our asset we have Heat Recovery Steam Generator (HRSG) which is 11 years old.
This HRSG utilize flue gas from Gas Turbine to make steam. Feed water comes in to the HRSG thru 6" pipe and exit as steam thru the same size pipe.
Steam pressure is about 740 psig and the...
