Hi,

Since Indian STD material is not given in PVElite. could anybody explain how to find ASME equivalent material for IS STD material.

also please let me know equivalent of :
IS-3589 PART-2
IS 2062 Gr A
IS 1239

Early replies are appreciated. Thanks in advance.



Thanks & regds,
Pramod

Hello Pramod

That is difficult. The only way of getting a near equivalent is to compare the chemical and mechanical properties with a known ASME material. That is the method stated in for example, ASME Section VIII, Division 1.

The difficulty is getting the mechanical properties at elevated temperatures.

In our software we take the material information from the material standards associated with the particular pressure vessel code.

Dear Pramod,

You can do one thing i.e. for IS 2062 Gr.A there are factors given in IS code which are to be multiplied with the stress values given in table-2 of IS. These factors are above 240 degree C.

I think this much info is sufficient for IS 2062 Gr.A.

M. Shukla,

many thanks for your Early Reply. for your Info, materials are under 200 degree C and at 4 bar pressure.

Mr. pramod,

IS 2062 Gr A equivalent material is SA 36. I will refer and give you other equivalent materials early.

Greetings to all people on this forum, since I'm a new member from today.

Pramod,
from your post, I'm suggesting that you are on some calc. using PVElite, and you don't have appropriate material in PVElite database...so you are unable to do your job.

If this is right, and if you have Indian material specifications you can easily retype all material properties in PVelite's material window.

Cheers.

There are 2 ways to put your material properties in PV Elite,

1) Quick and dirty way - click on the button next to material name in the input and then retype all the material properties. This window has the properties stored in the file.

This is a quick way, but remember if you change the design temperature this will make the program go to material database and get the allowables again at that new temperature and will overwrite your changes.

As kodzak81 wrote, you can use this method but set the design temperature before making any material property modifications.

2) Detailed and safer option - If you are going to be using the new materials again and again. then, it would probably be better to add these material to the database and select it.

From within PV Elite go to "Tools" menu, then choose "Edit/Add Materials" and select the material database to add materials to.

Once in the material database editor, press F1 and look at the help file. If you do not know some of the inputs, you can look at similar materials from PV Elite database.

The new materials will appear at the end of the database.

Let us know how it works for you.

Dear Pramod,

you can refer Bureau of indian standards IS2062 : 2006 SPECIFICATION for Low, Medium & high carbon steel, which covers IS STD material

you can order one copy of the same & compare laddle analysis (Chemical composition) & mechanical properties with ASME materials.

You will find that IS2062 Quality B material is parallel to SA-36 MATERIAL for an E.g.

Hope this will solve your problem.

The standard is easily available at mumbai stores.

hope this resolves your problem.

Thanks
