Dear Parag
You may like to contact us for a demo CD on AutoPIPE Plus software which
covers such buried piping analysis. It is Bentley product. You may even
contact Bentley Systems Mumbai if you are located in Mumbai.

> Dear Mr Sajit Viswan,
>
> Pipe is of 18 inch dia ie 457.2 mm ihad typed 0 insted of dec pt. length
odf pipe is 1.2 kms. i had worked on the data but unable to get the bending
stress as i'm not clrared what restrained and unrestrained pipe line meansas
i got the redy made stress calculated but i have to verify them as part of
my project, the value of bending stress for restraind pipe is 17014psi but
how it comes i cant find ou pls help me.
