Hi Marsillam Tambunan

I think you will find most people will not be willing to send you isomtric drawings as they would be classified as confidential. Have a look on the internet and you will find some very helpful information including generic iso's etc.

I recently came across the following while searching for information on one of the ASME codes and recommend having a look at it if you are a beginner to pipe stressing. It is based on B31.3 and I thought it was a very good starting point, (along with the full version of B31.3 of course).
