Thickened Shell Insert / Repad
Thickened Shell Insert / Repad
(OP)
I was wondering if anyone could help me with this one.
I have a client who wants to vefify that their tank was built in accorance with API 650 Repad dimensions.
ALl the manholes and nozzles over 2" were installed through thickened insert plates.
Tank Details:
D - 120'
Height - 32'
Fill Height - 28'
Bottom shell course tnominal - 0.500"
Thickened insert plate - 0.750"
Nozzles range from 3" - 30" Manhole.
Essentially, I am trying to figure out if Table 5.6B, Columns 5 & 6 apply to thickened shell insert plates when used to provide reinforcement to nozzles.
RE: Thickened Shell Insert / Repad
Note that the tank should have been built in accordance with API-650 reinforcing requirements, not necessarily repad dimensions.

Unfortunately no I don't. The shell material and thickened inserts material is unknown.

It will help considerably if the tank drawings and/or the nameplate are available.
You could spend the rest of your life re-checking the design of everything in a refinery.
