Wise words Gents.
Thank you very much.
The advice given has been very valuble.

I am aware of my limitations.
I am NOT a vessel engineer so i intend to stay well away from assesing the H/X

What we will do is to run some preliminary calcs to ensure the loads are reasonable on a fully corroded H/X and advise the client that a full inspection/assement of the H/X system is in order.

On a second note, the H/X material ASTM A201B is no longer in use (superseeded by 515)

Do you any of you guys have the basic data for WRC 107 Calcs?.

ASTM are sending a copy of it in the post but i am pushed for time


Regards Tim.
