Based on what Metengr said, I headed back to the pipe yard to try matching the bevels to the drawings sent by the mill, which I have enclosed.
Basically, bevels do not quite match. For example: On the 18" x .938" pipe, the mill claims that bevels were fabricated as per Fig. 3A. However, there...
Metengr, so in the practical world a contractor should not have any issues stringing a pipeline with bevels as per ASME B16.25, right? but can end user reject pipe because the bevels are not plain bevels as per API and instead as per ASME B16.25?
A Spanish mill furnished carbon steel pipe as per API 5L with bevels allegedly as per ASI B16.25.
My question is the following:
"Can bevels as per ANSI B16.25 be accepted instead of plain end bevels as per API 5L (30 deg angle + 5 deg / - 0 deg, with a root face of 0.063" +/- 0.031")".
Would...
Metman - I looked around in the ASTM site and eventhough there is extensive info. I still could not find what I was looking for...basically I'm looking for photos of rust/corroded surfaces with a rating so I can compare to actual specimens and visually determine the degree of deterioration...
I need a benchmark/reference to compare actual rusted carbon steel pipe in order to assess its degree of deterioration.
I have seen some marine surveyors carrying some laminated photos with ratings which they use to compare to the actual material being evaluated.
FYI - I was not able to find...
We obtained the following results from a ring sample of API 5L/ASTM A106 CS pipe:
ASTM E45 Inclusion Rating
Method A: Inclusion Content
A 160mm2 specimen was polished through alumina and examined unetched at 100x.
The worst field was compared and rated to ASTM E45, Plate I-r.
THIN HEAVY...
