Steve
Thanks for the calculator it will be useful for future use.
Unfortunately the web site http://www.matweb.com/search/SearchSubcat.asp
that you and Rodger directed me to does not contain the required data for
Pipe Grade HDPE.
Any suggestions?

Alex

Alex,

I posted this a few months ago.
This might help? It's a simple vessel calculator. Input Young's Modulus
and Poisson's ratio for the material.

Use the site Roger referenced to get the values:

If you don't have MsOffice you can download a free XLS viewer from:

I have another vessel calculator somewhere, I have to look for it.
When I come across it I will post it.
