(OP)
This double wall tank storages H2SO4 and is made of HDXLPE (crosslinked HDPE). Wall thickness calcs were done according to ASTM D 1998.
Is there a standard similar to API 653 for non-metal tanks? intention is to assign inspection interval and use some kind of "inspection checklist" similar to API 653 Annex C.
Thanks,
Corgas

I asked same question and was told that tank wall thickness were calculated according to ASTM D 1998.

I would take the -653 checklist and delete everything that does not apply, and call it my "HDXLPE H2SO4 Program" checklist. Some kind of Internal Inspx should be included.
