Hi everybody,
I should be grateful if somebody guide me to FF of Natural Gas Pressure Booster Stations. Is there any NFPA code covering these stations?
I've found following link regarding induction of cabling on buried pipeline:

The guys in above article describe a method for mitigation of AC induced current on buried pipeline. In our case the buried gas pipeline...
Thanks David and BigInch, a lot for your responses. Actually duw to Client RECENT requirement, we are going to lay a 16" U/G natural gas who feeds from north to south a power plant and the power output should goes by a surface trench (230kV) from east to a western 400kV substation. So the...
Hi Everybody,
Is there any limitation on cabling HV line (230kV) in a trench over a buried natural gas pipeline?
Any reference to standard (or credible article) will be highly appreciated.
Regards,

That's what i want to know, why designer is trusted to steel for larger sizes.
To MJC:
GRE stands fot Glass Reinforced Epoxy. The jump from 24" to 66" is from FEED P&ID, which doesn't include any size between.
Does anybody out there have experience with U/G erection of GRE or GRP...
pennpiper:
Your list actually confused me. Would you please share a sample one (or reference to net link?)
to BigInch:
Aren't Max. and Min. flow, temp. and pressure related to "UTILITY SUMMARY" document?
Thanks BigInch for your reply,
Questions:
"Either there were too many small lines and they forgot to change them..."
What does that mean? the subject is larger size. Are you in favour of CS?
"...or a higher yield strength is required for the same pressures when using those larger diameters."
Why...
Hi everyone,
In one of our projects, the FEED documents contain PMS of entire plant, so we shall follow it. In definition of "COOLING WATER-SEA WATER (UNDERGROUND)" service, the pipe material is Copper-Nickel, for small sizes(say 3/4 to 4) , GRE for 6" to 24" and API5L-B (flake-lnd at field) for...
