@HI ShabsRBI
As you mentioned
With Class #300 the allowed Pressure at 200 Deg C is 4380 Kpa, which is well above the design pressure of 1496 Kpa.
YEAH. I agree to go with #300 P-T rating.
Thanks for reviewing and correcting my document.
katmar sir
Thanks for your comments and it is really helpful for me. i will come there with new thread after i design our conceptual fire hydrant system.
katmar sir
but that was not what you were asking (I don't think).
yes. but anyhow we could not run the plant with single landing valve so if i have to design it for 20 numbers for the same type of nozzles.
(20 Numbers of single headed landing valve for same flow rate of 900 lpm.
then how much...
katmar sir
You need to size the pump and piping so that at the desired flowrate of 900 l/min the pressure available at the outlet of the valve would be 7 kgf/cm2.
yes. i will design my pump for the flow rate.
If you provide a pump with a capacity of 900 l/min at 8 kgf/cm2 you will have 7...
LittleInch sir
How long it could be is 15 meters so my point is at the discharge nozzle flow rate. The outlet of the single headed landing valve not the hose nozzle. so can i consider flow rate of 900 lpm for 63mm nozzle ?
hi
i don't know whether this sheet might be useful for you or not but anyhow i am sharing this sheet.

Hi all
I have a doubt on flow rates for fire hydrant landing valves. we have selected 100 mm X 80 mm Oblique type single head landing valves for our plant and we get 63mm orifice diameter but as per vendor specification it shows testing flow rate around 900 liters per minute at 7 bar pressure...

Take it seriously into account with your design.
of course it has to be taken into account seriously. i understand my responsibility that's why i insist my management to go for oil free compressor with 99.99% purity level to avoid the consequences of the any contamination with the...

We have suggested to supply oil free compressor only.

thanks for your information. we have already installed the same carbon steel receiver in our plant so as you told, i will have to consider this point.
they have mentioned as lubricated compressors, this should be noted. Thank you sir.

i have got the quotation and i attached here.
but Dew point is also key together with oil content.
can you please explain me about this ?
i don't understand why we need dew point and oil content of ?

Hi
We need nitrogen plant for our API plant for vacuum breaking and we have selected the flow rate around 20 Nm3/hr but we have no data apart from this.
Does anyone help me what are the parameters to be considered for nitrogen plant selection for this application if any guide available please...

Thank you sir for correcting the errors in my sheet.
