Thank you Kiranpatel and prex. I have checked the wall thickness based in the formula for buckling of high thickness pipes and because the high internal pressure selected for the pipe (roughly 250 bar & the deeper water is 700 m)the external pressure drives to similar thickness.
For my...
Thank you very much Kiranpatel I will try to find the references but it will take me time.
Regarding the buckle arrestors, I suppose they are designed for the laying time and that the external pressure for 900 m is negligible compared with the stresses coming from the laying ?. Am I correct?
I...
Hello, I am looking for a formula (in International Units) for checking a pipe of 14" under external pressure. For internal pressure I use Barlow's formula. Is there any formula for determining the spacing between buckle arrestors?
Thank you very much in advance.
Thanks a lot MortenA, the example of the water is really clear.
There is still something about this that I am not sure. When do you go to the "fluid zone" if your liquid is over the critical pressure & you heat up? I suppose when you cross the isothermal of the Tc. Is it ok?
If you...
Hello, I have a liquid hat I want to pump. The composition of the liquid varies, so the phase envelope also chanches. Some times, with the differential pressure I want to use, the "liquid" goes over the critical pressure.
What are the consequence of this? Can I use a normal pump?
If...
For short pipelines and gathering systems I use Weymouth formula. It works properly and the friction factor is function of the diameter. This allows me not to look for iterative solutions.
If you use Colebrok you need a graph with the friction factor, you can find in Section 17 of the...
Thank you sbi, but I am not selecting any location and what I need is to begin to learn about this matter and to know the general rules steming from safety distances. I am sure that Local Emergency Comitee will be contacted if USA location are selected but unfortunately i am not in this point.
Hello, I am looking for recognised standards where I can find limitations to the plants locations in USA and EUROPE.
In particular I would like to know if a Regasification Plant can be situated, near a town, near a football stadium, near a rail road, near a Nuclear Power Plant, near an existing...
Hello, I am interested in finding standard "data sheets" for equipments of REGASIFICATION PLANTS, cryogenic pumps, reliquefiers, open rack vaporizers, sumerged combustion vaporizers, cryogenic vessels, cryogenic pipes.
Is there a book with a compilation of these "data...
I am looking for information of LNG liquefaction plants.
What are the different process?
What are the tipical costs?
What are the influence in the cost?
Thank you very much in adavance
