Hi,
I search a formula to determine the orifice sizes of my relief valves. The operating pressure is 70 bars (Class 600). I know the flow (Oil and Gas) which circulate in my pipes (2300m3/h at 70bars).
How do I fix opening pressure? What are the flow to evacuate?
Thanks you to help me.
Hello,
I'm working about on-shore fiscal counting system design. The whole of my pipes and devices are classed ANSI600. My pipes are in carbon steel A105.
I would like to avoid to calculate for each diameter, the thickness.
In Industry, Schedule 40 or 80 is often chosen.
Could use one type...
Hi,
I'm working about the integrated counting system design and I wonder how to design my vents for gas and liquid.
Norsok P-001 speaks about maximal velocities in vents equal to mach 0,5, but it creates very large velocities. In practice, are there sizes which are preconized?
Hi,
I readed in Norsok standard I-104: Fiscal measurment systems for hydrocarbon gas, a sentence which I don't understand about instrument ball valves. I quote:"For fiscal measurement applications, ball valve manifold block or an assembly of ball valves shall be applied(3/5-valve)". What does...
Hi,
What are the advantages or disadvantage of full bore or reduced valve? In my case, I want install Trunion DBB valves for the sectioning but I dont't know if I must choose a reduced or full bore valves.
Thank you to help me.
Hi,
I'm working about hydrocarbon counting system and I would like to know the pressure level for pressure test (hydro and pneumatic). There are two cases:
1)Gas hydrocarbon:
Pressure Nominal: 100 bars, Class ANSI600
2)Liquid hydrocarbon:
Operating Pressure:60 bars
Pressure Design: 100 bars...
Hi,
I'm HVAC engineer in France, and I'm working about an unsual subject, the petroleum counting system design. I would like to determine the inside diameter of pipes. It seems that it would suffice to fix the diameter in order that the maximal flow could circualte at maximal velocities.
Does...
