Since no response from other Forum, May be this is more appropriate place!
Dear All Hello/Good Evening,
Kindly oblige through guidance on the %age sampling for Inspection/Testing for captioned subject Pipeline of Chinese or Korean Origin
Also guide with preferable technique to be employed i.e.
1)Ultrasonic
2)Radiography
3)Electromagnetic(Eddy Current
5)Any other tests needed for this "longitudinal" Seam Welded Pipe Type.
Pipeline involved is around 6100 Rft for a refinery piping Project.
Early Help with applicable Code/Standard?good Engineering Practice reference,if any will be highly appreciated.

RE: ASTM A53 GR B Sch-40 8" Dia ERW Pipeline Testing& Inspection Criteria
i would ask for chemical and physical tests from each heat of pipe
100% radigraphy of each random length
RE: ASTM A53 GR B Sch-40 8" Dia ERW Pipeline Testing& Inspection Criteria
Can any one else come forward with further Comments/suggestions,If any!
Thanks in advance.

Second....Who is doing the mechanical engineering for the project and which international standards are being followed? It is these standards that will determine the degree of NDE for each type of pipe.
Third.... Where are your piping line specifications ? Where are your design drawings ? Are you going to purchase 6100 ft of the same type of pipe and then try to use it in the project ?
What kind of "refinery project" is this...!!??

1)Refinery Firewater
1)At or around near ambient temperature
(Under shade max.53 Celcius)
2)Pressure at or around 12.0 Barg(usual max.)

If you're concerned about what is available, go inspect it at the pipe yard and perhaps later plan on doing a longer duration hydro.
