Good morning my dear friends,
I have to do the analysis for the condenser supply and return lines. My pipe material is A36. This material is not listed in the Caesar II material list.
Can I know what should I do? Which equivalent material I should consider in place of A36?
Waiting for your response.

Have a nice day ahead.

Regards,
Ankur.

Excuse me all the members,
I need your suggestion.

Regards,
Ankur.

This are the equivalent material for A36:
JIS G3101-SS400
ASTM A283 Grade D
EN S275/ BS 43A

Thank u marian, but in Caesar II which material I will take. The name which u have given is not in the material list in caesar II.

Kindly suggest.

Regards,
Ankur.

not all material available on the market are on the data base, you can add your material in the data base, you just need to type the correct material property
for this you need to find the temp, exp coff, allow stress, elastic modulus for this particular material

Thank you Marian.

Regards,
Ankur.

Good morning Marian,

Can you tell me where I will input the exp coff valve in caesar.

Regards,
Ankur

sorry its value not valve.

Can any tell the answer.

Regards,

If you want to add this material to the material database, you can use "\Tools\Material Database Editor". Please read the documentation on this tool before you use it (at a minimum you will need two entries for your material: one for "All Codes", and one for your specific Code of interest).

If you don't want to add this material to the material database, then you must specify all of the material properties in the piping input. The expansion coefficient (in units of length/length) can be entered in the Temperature field (see the Help text on this). Note the units are lenght/length, you need to take care of "delta T".

Thank you Richard.
I want don't want to add this material to the material database, so I will input all the material properties. I input all the properties but for inputting the expansion coefficient, the caesar is not taking means I am not able to input the expansion coefficient. While going through the Help I found that if I get the expansion coefficient .009475 in./in then this valve would be entered into the appropriate Temperature field.
So I didnt get in which appropriate Temperature field its saying.
There are total 9 operating condition, so in which temperature I will input the expansion coefficient.In 1st temperature I input the design temperature.
Please suggest.

Thank you.

Regrads.

Then put it in T2, and include an OPE load case that uses T2.

Ok thank you Richard.

Regards,

Richard,
As you told to input my expansion coefficient .009475 in./in in T2. The same error is showing in caesar II that is
"Temperature Fields on element 10 to 20 Expansion Coefficient for USER DEFINED materials must be set by the user".

Kindly suggest.

Regrads.

You can't put the design temperature, or any other temperature for that matter, in any of the Tx fields for the USER DEFINED material (material #21). The reason is that this is a completely user defined material, there is no information for CAESAR II to look up, like what the expansion coefficient is for a specified temperature. So for any temperature you want to analyze (design, operating 1, operating 2, etc), you have to input the corresponding expansion coefficient.

Thank you very much Richard, now its not showing any error.

Thanks and regards.

Good morning all the members,
I got the expansion coefficient 6.5 E-6 in/in/F (0.0000065 in/in/F)and this valve I have to input in T1.
Now the problem comes, My T1 unit is degree C and the valve of expansion coefficient is in Fahrenheit (F).
So shall I have to input the expansion coefficient 6.5 E-6 in/in/F (0.0000065 in/in/F) directly without changing the unit or else I have to change the unit from Fahrenheit to Celsius?
After converting the expansion coefficient 6.5 E-6 in/in/F (0.0000065 in/in/F) into celsius I am getting -17.78 degree C.
Kindly suggest.

Regards,

You need to convert that number to mm/mm/C, then you need to muliply by the delta Temperature in degress C. (Note in my post of March 5th, I said the units should be "length/length", not "length/length/deg".)

Thank you very much Richard. Once i will finished I will let you know.
Thank you for all your support.

Regards,
Ankur.

HI Good evening friends:,

Same issue coming for me also.
When i Entered my design Temp and operating Temperature, I got the error while executing the error checking by saying Temp coefficent.

So i studied and i got the Temp coefficent for my Material , then i entered that .0014.in temp box. But whether this is suffient , where i will enter my design and operating temperatures. pls guide me.

Richard,
I have question regarding your post on 03/12/12 at 10:58 AM in the above matter.
My question is shall we need to Multiply by the delta Temperature in degress C to mm/mm/C? If we will Multiply then the unit will become C square.
Kindly know the members opinion along with Richard too.

Thanks and regards,
Peter.

Good morning all the members,
Richard, I went through the Help Text and found that they havent mentioned about delta T. But if you go through your post dated on 03/05/12 11:17 AM and your last line of second paragraph you have mentioned about delta T.
I am confused. Please need your support Richard.


If you go to help text and see the example, it showed as mentioned below:
"For example, if the user wanted to enter the thermal expansion coefficient equivalent to 11.37in./100ft., the calculation would be:

11.37in./100ft. * 1 ft./ 12in. = .009475 in./in.

This would be entered into the appropriate Temperature field."

My value is coming 0.3in/100ft and after converting into length/length its coming 0.00025.
So this value 0.00025 I will entered in the temp field.

Kindly suggest.

Response awaited from all the members.

Regards,
Ankur.

Yes, you are correct. The units of the coefficient entered in the temperature fields of the Piping Input dialog must be "length/length".

Thank you Richard.

Regards,
Ankur.
