Hi
We got at project with a steeltank, where the bottom is insulated with foamglas. Between the insulation and bottom, we plan to place app. 50 mm af dry sand. The buyer are requiring annealing of the welds.
My problem is that the supplier of the foamglas is worried that the foamglas in theory...
Thanks to both of you!
Especially the first link at www.ast-forum.com was usefull.
Regarding thermal insulation, we are planning to use foamglas or equivalent, maybe substituted with brick type insulation where the plates are being welded.
We would like to avoid the bitumen-sand if possible...
Hello
I can see that bitumen-sand is a returning topic in this forum, therefore apologies for re-opening the subject.
Our national recommendations (Denmark) state that a concrete slab with a layer of bitumen-sand above it can be accepted as a secondary barrier for a steel-bottom tank.
But as far...
