@1503-44, I will use a City gate to reduce the pressure and then set another reg at the customer to 450. The reason I need that higher pressure at the inlet- in the region of 800 psig is that we are looking at potentially building out our system for additional load.
Thank you for taking your...
A better statement of the problem is as follows:
A customer wants us to deliver 40,000 MSCFD of natural gas at 450psig.
We have the ability to get gas from a transmission pipeline at 975 psig max, use an interconnect and drop it down to whatever pressure we are comfortable with ( I chose 800...
Thank you all for your responses. Deeply appreciated.
@littleInch: Wow!. 20 years! I believe I was starting out my career in the power industry back then. Am in the natural gas business now in an area which is new to me.
Think I will need to give some more insight on the issue I am facing.
Thanks
Hello All
I am new to this field and am looking for some guidance/suggestions in calculating the appropriate pipe size for specific conditions for natural gas..
Flow Rate 40,000 MSCFD
Length of Pipe: 15 miles
Inlet Pressure: 800 psig
Temp: 60 degF
Downstream pressure: 450 psig
Pipe...
This one's a beaut!! It has 8 leads going into a three- lead vertical manifold. The three leads out of the manifold then go to the turbine.
Your observation of 6d seems okay since this is what we have, thereabouts. Just thought that there may be some calcs out there. The budget limits how much I...
I am doing some research into what length of pipe is appropriate for mixing hot reheat steam before going to an IP turbine. Here's the facts. There are two boilers putting out a total of 5.9x10exp6 lbs/hr total at 585 psig. The steam from both boilers leave thru' 4 24" lines each and meet...
Thanks all. Good points. I found out that a turbine manufacturer stipulated not more that 12,000 feet/min as entry conditions to the reheat stop valve.
As an additional qustion, have you seen reheat lines at the turbine with a flange? For example the U-bend that comes to the top of the turbine...
I am new to this forum and just wanted to start a discussion on allowable steam flow velocities in reheat steam piping.
Crane No.410 gives an acceptable upper limit as 20,000 fpm. However, I am interested in the basis for this. Is it because of the pressure drop associated with this, noise...

I am not a metallurgist but I forwarded your request to one and his reply is below:
The correct spec is A403 WP304L. WP means "wrought" product for austentic
steel. The "F" (forging) is used for ferritic steels. F304L makes no
sense. It's not listed under A403...
