normalized rolled plate

normalized rolled plate

normalized rolled plate

(OP)
can we normalized rolled plate ( not as rolled or normalized) used for U stamp ASME pressur vessel

RE: normalized rolled plate

Your question is not clear regarding normalized plate. Can you please re-state? Plate materials in ASME code construction is limited to approved materials listed in Section II, Part D or code cases.

RE: normalized rolled plate

If the material is permitted for use by the construction Code in the normalized condition you may normalize it. The material must be represented by acceptable mechanical test results meeting the specification requirements. The testing may be performed by the mill or the by you on a coupon(s) which was normalized.

RE: normalized rolled plate

(OP)
we have received the plate in three condition

1. As rolled

2. Normalized - Normalizing done after rolling

3. Normalized rolled - online normalizing during rolling

my question is can we use normalized rolled plate in ASME pressure vessel

RE: normalized rolled plate

What is the material specification?
What is the Code of construction?

RE: normalized rolled plate

(OP)
material is SA 516 Gr. 70 plate thk 10mm
code of construction - ASME Sec- VIII Div-I

RE: normalized rolled plate

ASME REQUIREMENT: Plates with thickness less than or equal to 40 mm are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both (If clients specification says so). Plates over 40 mm in thickness shall be normalized.

RE: normalized rolled plate

Yes you can. If the cost is same for all three then go with "Normalized rolled".

RE: normalized rolled plate

(OP)
can you tell where its written in ASME Sec-VIII because our third party inspector not accepted the normalized rolled plate for U Stamp ASME Pressure vessel

RE: normalized rolled plate

ASME SECTION II-A. Heat treatment section 5 of SA 516. FYI! Normalized rolled plate is nothing but two process combined into one(As rolled while undergoing normalization.

RE: normalized rolled plate

The stipulation is that after rolling the plate must be heated to the minimum temperature for austenitizing before cooling for a normalization heat treatment. Hot rolling and air cooling is not normalizing, it is as-rolled.
