Standard Support Lug attachment of Pipe - WRC107 or NozzlePro Calc

We are specifying lug allowable load - here, we need to specify pipe matl, pipe nominal thk, corrosion allowance on thk, manufacturing tolerance on thk and design pressure.

Is it necessary for B31.1 or B31.3 code for pressure design - as due to local load in sustained cond, pressure integrity may get lost, if underdesigned.
