Lamination Test Of Pipes According to ASME B31.3
Lamination Test Of Pipes According to ASME B31.3
(OP)
hello to all
our design code is asme b31.3 and we want to get the pipes lamination examination, which reference is practicable for that? dose asme b31.3 have any suggestion for that?
thank you

In general I can’t quickly think of a situation where your pipe is so thick and fabricated in such a way, that one should concern about laminations.

ASME B31.1 and B31.3 do not permit the use of any material.
I am aware that some thick carbon steel sections used to construct structures must have an examination for lamination defects

Lamination is a rolling defect.
It is a common occurrence where plates are involved, for example, in the construction of storage tanks. However, for large diameter pipes which are made from plates, lamination is an issue.
You can find out lamination by ultrasonic testing.
Before ordering the pipes, check the ASTM specification for any Supplementary Requirements that puts a check on inclusions etc. and subsequently laminations.
I have come across situations that after years of service, lamination in large diameter pipes have been misreported as HIC !!!
