Copper Water Pipe Properties

Copper Water Pipe Properties

Copper Water Pipe Properties

(OP)
I am doing an advanced FEA analysis that involves permanently forming a copper water pipe (C12200 ASTM B88).  My problem is that I cannot find any DETAILED stress-strain curve information that includes the nonlinear yielding portion of the curve....all that's normally listed in elastic modulus.

Does anyone know where I could find this type of detailed information for copper water pipe?  It seems like something that must have been done a hundred times and be in the public domain.  I've checked www.copper.org but they too don't offer that detailed information.  The cost to do this test for me is prohibitive.

Thank You

Thanks for the response, but I don't see water pipe material listed in the curves.  I've seen copper pipe referred to an 106, but never 102, 122, or 220.  Are you implying that I can use one of the curves listed?  I ruled them out because I didn't think they applied.

Thanks

cnuk;
You have asked this question before-see the thread below;

RE: Copper Water Pipe Properties

cnuk,

Most test labs only require ~ $100 to perform a tensile test.  Are you saying that this is prohibitive?

RE: Copper Water Pipe Properties

cnuk,
You need to provide more specific information than just the alloy.  The properties depend upon the thermal and mechanical history and resulting grain size.  What is the ASTM B601 temper designation for your item?

ASM Handbook vol. 2, 9th Edn., p. 263 has UTS, YS & elongation values for C12200 tubing, 25 mm OD w. 1.65 mm wall, in 4 different tempers:
temper        UTS                  YS*          Elongation
OS050  220 MPa, 32 ksi    69 MPa, 10 ksi  45%
OS025  235         34         76         11      45%
H55       275        40        220         32      25%
H80       380        55        345         50       8%

*0.5% extension under load.

The stress-strain curves in my references seem to be all for bar, strip, plate, & wire forms.  If the stress-strain curve is really "the million dollar question" for your somewhat uncharacterized pipe or tube, results should be obtained by testing, rather than guesswork.

RE: Copper Water Pipe Properties

Dig out the ASTM books and see B75,B251 along with B88. Make sure you look at all the references

Make sure you really want B88 tube. There are other problems that go along with this spec.

metengr:  Yes I asked before but the information did not answer my question.  Thus I was trying to ask it again in a more specific fashion hoping to get some assistance.

TVP:  $100. wow.  I was quoted $1500 CDN for one tensile test.  Seems like I'm getting gouged.

kenvlach/deanc:  Good info.  I will dig up the books and confirm the exact spec I am using.

Seems like an actual test would work best and if the price is really $100 it's the best approach.
