ASTM A200 T9 vs. A213 T9

ASTM A200 T9 vs. A213 T9

ASTM A200 T9 vs. A213 T9

(OP)
I want to conduct an life-evaluation test (including creep test, tension test) on ASTM A200 T9 Heater Tube.

But I found that ASTM A200 T9 code is expired.

I heard that ASTM A213 T9 code matches exactly with A200 T9 code.

Then where is the official comment about this matter?

I can't find it.

And is it possible to conduct a test based on A213 T9 code?

Is it exactly same?

Thx for your kind answer. :)

RE: ASTM A200 T9 vs. A213 T9

To add to the above, ASTM A200 specification was withdrawn in 1999. The ASTM A213 specification is now applicable for intermediate alloy-steel tubes for refinery service.

The creep test is not part of ASTM A213. ASTM A 213 specifies tests to evaluate mechanical properties and fabrication for tubing.

Are these in-service tubes that you are interested in for creep life evaluation?

 

RE: ASTM A200 T9 vs. A213 T9

A 213 shows T9 in three locations.  These include the UNS designation, chemical composition limits, heat treatment type and tempering temperaature, tensile strength, yield, elongation, hardness, etc.

In case of creep test, we conduct a test based on ASTM E139-06.

Anyway I should know tube's mechanical properties or chemical composition or something like that. And to know LMP value of tube, I should know the exact code of tube.

So then to know the characteristics of A200 tubes, can I use A213 code?

Does A213 substitue for A200 exactly?

Or do I have to reference A200 code?

If in cases - two tubes are based on different code, used one is based on A200 and new one is based on A213. Is it possible to substitute A213 for A200? Or vice versa?

RE: ASTM A200 T9 vs. A213 T9

Dawoon;
First off, ASTM A 213 material specification is now being used for ASTM A 200 Grade T9. This is not a code this is a material specification.

Second, yes, you can use or substitute the stated mechanical properties that are in ASTM A 213 Grade T9 for tubing that was originally specified as ASTM A 200 Grade T9.

The Larson Miller Parameter (LMP) of the tube material is not in any material specification, it is a creep rupture test method. You would need to obtain creep rupture data from testing and plot this data using the LM parametric equation to extrapolate creep rupture life based on a known service temperature.
