I need help on calculating liquid loading for a horizontal passive filter separator using natural gas as the product medium. natural Gas SG 0.58. Is there any empirical formula that governs such calculation . Any industry standard that help calculate these parameter?
Does the lube oil pump return piping necessarily be sloped to 2% when it goes from the process pump return ports to the lube oil tank reservoir. Does it need to have gravity flow to the reservoir, since the lube oil pump is continuously operating and has sufficient head to circulate the SAE 40...
but exceeding the piping pressure class , isn't it a violation. I know you can set the PSV's at the pressure class for eg:- for ANSI 900 you can have the PSV set at 2220 psig but setting it at 2350 or such is violation of the piping codes . I know ASME B 31.8 tells to not go above 10% of the...
Exceeding the design pressure as set pressure for the PSV for a ANSI 900(2220 psig) pressure system. What kind of problems can you face while in operation. following are the operating parameters.
Design factor for all fittings and piping is at 0.6 and materials adhere to API and ASME standards...
I need to understand when to use a weldolet connection vs threadolet on any pressure class piping ( ANSI 150, 600, 900, 1500).
So far I know that weldolets tend to have less stress concentrations than threadolets , but the question that's bugging me is why use threadolet if weldolets are so...
Please read Industrial Pigging Technology: Fundamentals, Components, Applications by Gerhard Hiltscher, Wolfgang Muhlthaler, Jorg Smits for better understanding and not correctly accomodating for the pig l/d ratio.
Its weird to know that more than a 100 year old practice doesn't have a standard written for correctly sizing the pigs. A google search is effective if one knows what exactly he is looking for, which proportionally reduces search time .

I see a lot of suggestions here made are as per empirical testing or based upon experience which would not help in documenting a design change. On my client side (Enbridge) the individuals need more than assurance that a long radius bend is enough for pigging.
During my research I came across...
Thanks everyone for your valuable guidance . With all of you're support i was able to find the controlling factor for selecting pigs on long radius bends. There's an empirical rule that the ratio of the length of the pig to diameter of the pig should be less than or equal to 1.5 for long radius...
I have to pig a 24 inch crude line with a foam pig and I am unable to decide what size 90 deg elbow to use .
Should I choose 90 deg elbow of radius 1.5 D or 3D. I would also appreciate if you can refer me to a standard that has associated information about it as well.
