The largest composite steel tank in China
Thread Content
I would like to ask my colleagues: what is the capacity in cubic meters of the largest composite steel tank currently in use in China? Should the lower plate positioning block for the composite cricket tank be welded on the inside or the outside?
For composite steel tank positioning, if welding is done on the inner side, is it possible to weld to the base layer or the cladding layer as well?

I have not worked with spherical tanks made of composite panels before. From a technical perspective, it is best to place the assembly fixtures for composite panels on the outside, that is, on the base layer. This reduces the need for welding on the composite panel itself, especially welding related to temporary fixtures which are prone to causing welding defects. It also prevents the composite panel from peeling off
Can those lifting lugs at the bottom be welded only on the inner side? Is there any other method?
Can stainless steel lugs be welded directly to the inner lining? Can the impact on the adhesion of the coating be evaluated?
What you mentioned is indeed a problem; for spherical tanks made of ordinary materials, the lifting lugs are welded inside
It’s really hard to say; I’ve never seen anything similar

Generally, it is necessary to remove the stainless steel; how can calculation be done without removing it?
