Sizing of Piping

Big. How long is it? I know, I know. "How long is it? All the way from one end to the other".

I'd suggest that you look on the internet for sizing charts, or hire an engineer to do the calculations for you.

Does it frighten anyone else that someone is dealing with this amount of natural gas and doesn't include the most basic of parameters necessary to answer the question posted?

It scares me to the point of wishing there was a way to delete these lazy irresponsible posts into oblivion, with a STRONG admonition to the afore described posters to do their own work.

Homework doesn't normally have a very good chance of killing hundreds of innocent by standers like posts such as this one.

MUNAWWAR HUSAIN SHAIKH, do you get the gist of what we are trying to say here?

Here's another one for ya.

I hope this guy isn't the foreman.

I think he took the tender job of bring in gas to Pakistan from Iran. Easy, grease palm and take the job. It does not matter if you don't know a shit about it. Idiots like us at CR4 are always there to engineer for them. Next, now he will revert back " how you calculated" thinking I am an idiot again to give him.

Chaotic,

God has his own special way of thinning the herd......

Incompetence is often punished quickly and severely

Yes, but the collateral damage.

Try 6mm i.d., Boss.

Ha ha you are great, boss.

It depends on the pressure. If the 15,000,000 m³/d is Nm³/d, the actual m³/d may be less. As a rough guess, use Am³/d, and size for no more than 10 m/s velocity. For a better design, use a pressure drop formula to calculate pipeline losses at various pipe sizes, and the compression costs to meet the pressure drop conditions.

NATURAL GAS FLOW RATE 15,000,000 m³/d pressure of p = 101325 Pa and natural gas temperature of T=288.15 K.

150,000,000/24 = 6,250,000 m3/hr

18000 mm pipe = 7,257,600 at 8 m/s velocity

I think he probably meant the flow rate was referred to those P and T conditions, not that those are the actual conditions. Otherwise it's a big coincidence P and T are exactly standard, 1 atmosphere 15°C.

I'd expect the actual pressure to be several bar at least.
