thanks for all ,
Using nitrogen is expensive but my line will work after 3 years at least (phase 2 ) for that i cant leave it without nitrogen , i used dry air with acceptable dew point -14 . after i m gonna to preserve it with nitrogen.
i wonder how to calculate the volume of N2 in liter...
thank you for all responses
after the supplier This is the best possible value available for the required process conditions but in my datasheet the margin shall be at least in 1 m .
hello hope you are doing well
about the margin between NPSH disponible and NPSH required in centrifugal pump ,
with
design pressure 11 barg
design temperature 90
RPM 1200
process fluid water with traces of co2 and condensate
discharge pressure 4 barg
NPSH margin is 0.5 m , is it enough ?
Hope you are doing well
About horizontal pressure vessel installed 13m on a rack, upon installation and in order to achieve levelness the sliding plate was removed.
Is removing the sliding plate acceptable and can the vessel slide freely without it on the rack?
thank you ,
my question it s only about the possibility of replacing carbon steel with HDPE in chilled water system for the following reasons
-simple process and capable of producing consistent joints
-reducing the risk of joint contamination
-easy of assembly and to repair
-reliable
