I worked on a pipeline in the US. Our test pressure was 1440 PSI, max working pressure was 1170 PSI. This was on a 16" diameter gasoline pipeline. We seldom operated more than 850-900 PSI and that was the pressure measured at the discharge of a pair of 1500 HP centrifugal pumps in Lemont IL. that was pushing product up to the next booster station 50 miles away. Wall thickness was 0.375". The pipeline was installed around 1960 and it is still in operation today (Hammond Indiana to Milwaukee Wisconsin). For that particular line we had 1-2 1500 HP pumps in Hammond, 2-3 1500 HP pumps in Lemont, 1-2 1500 HP pumps in Gurnee. Flow rates could be up to 8000 Barrels/hr. (around 5600 gpm) Usually on the suction side of the pumps in Lemont and Gurnee it was coming in at 150-300 PSI
I was thinking the same thing. It doesn’t seem to be welding because there is leaks coming from all areas..... No one can say for certain unless the person who uploaded it tells us.
I would really like to see how the standard method for calculating failure worked for this test and hence I would need the following:- Diameter- Wall Thickness- Pipe Grade (it says X42-X52 on the pipe?)- Defect Depths- Defect Lengths- Defect Shape (if actual)- Failure PressureWould anyone be able to help?
