RE: Sampling size and distance for Petrographic test
Remember that for petrography, you'll need a destructive sample that must be repaired for the in-place pipeline. This can get both problematic and expensive.
Why do you need a petrographic examination? Are you having problems with the pipe?
RE: Sampling size and distance for Petrographic test
We wan to calculate remaining life assessment of pipe line and it 2.2M dia pipe wih length 1 KM off shore and there r manhole on every 100 meter with same material. We take sample of concrete from that man hole.
Can you again check how many sample we can take for testing ( 2 or 4 or on every 100 meter?) Is there standard for taking samples?
Or we can take 2 sample from both ends?
