In an application, we are planning to flush 891 bbls (37,414 gallons) of LPG through a 10" pipeline using water. Our initial investigation indicates that we will need roughly 500 psig discharge pressure to achieve the desired 150-180 psig downstream pressure. To inject water, we hope to utilize...
The application involves installing a concrete slab over an existing pipeline to protect it from loads due to a new road (highway) crossing. It currently fails the combined stress limits as calc'ed per API 1102
If anyone is familiar with the API 1102 calculations for pipeline stresses, I am...
I am trying to calculated the Darcy friction factor and got stumped.
The specification that I am following uses the equation below to solve for the transmission factor:
F(oil) = 3.6 Log (Re/8)
Where is this equation coming from?
Then it uses the equation: F = 2 / f(d)^1/2 to solve for the...
For hydrotesting pipe, I am using blanks (or skillets, pancakes, paddels, etc)to seal off at the flanges. Our company has standard tables in place for determining the wall thickness of the blank; however the numbers aren't jiving with the equation in ASME B31-3.
Some supplementary ASME material...
The application is to insert a flange skillet temporarily on two ends to hydrostatic test a 24" line. I am using the equation found in ASME 304.5.3 for determing the thickness "t" of Blanks. Namely, equation 15, where t= d(3P/16SE)^.5 + c. I am unable to verify the customers thickness...
