The issue is "Do they connect in some way?" I.E. do the seperate parallel delaminations - have "tentacles" that span the perpendicular directions between the individual delaminations. There are UT techniques to determine if they are present - and the presence of those tentacles can GREATLY weaken the structure. Delaminations on their own, may be OK. Hope that helps a little. ----------- Start Original Message ----------- : hello. : does anyone know how to evaluate laminations that where found in first course of 30000 bls oil storage tank . : subject oil storage tank -30000 bls : first course content 12 plates- : for each one at ut survey have been found 7-20 areas affected by lamination wide fro 20 x20mm to 800 x 500mm at depthes from 5 to 10 mm - nominal thickness is 14-15mm. : is rejected or accepted : -i will send the original report : thanks daniel ------------ End Original Message ------------         Reply  Translate  Close   Milt Deck Milt Deck 06:49 May-10-2004 Re: tank's plate lamination- evaluation To comment on the problem we would like to see the original report.
