Liability aspects for segmenting B16.9 elbows on site
Liability aspects for segmenting B16.9 elbows on site
(OP)
ASME B16.9-2012, paragraph 6.2.4 states:
"Although the elbow intended for field-segmenting must meet the requirements of this Standard, once the field-segmented elbow is cut, it is not a B16.9 product."
Now the question arises, does the manufacturer continue to be liable for the elbow?
My first thought is that the manufacturer is no longer liable for meeting the requirements of ASME B16.9. In extension, this would mean that the manufacturer is still liable for the other standards mentioned on the CMTR, for example ASME SA 234.
What are your thought?
Have you had problems with field-segmentable elbows where the manufacturer had to get involved?

I generally trim pipe instead of trimming fittings. Just a personal choice, either is acceptable. If I have to make something like a 19° change in direction, I'll do it in a hot bend instead of mitering pipe or a fitting that much. That way I have a tangent of straight pipe to weld to.
