1 Client:ACME ChemicalDate5/09/2012 report No. :ACAX 80005 Contact: John SmithPhone No.:555-836-2223 Year Built: 1970 Rerate Specification EXECUTIVE SUMMARY The Delaware Plant Reliability Engineer at ACME Chemicals in Claymont, DE requested Eagle Inspection Technologies to include Rerate calculations with the inspection report to support the proposed Rerate for the DOT Railcar ACAX 80005 to be set on stationary supports and continue in service as a stationary pressure vessel in Fluosulfonic Acid service.

2 This request was due to the requirements of the PA Dept. of Labor and Industry for pressure vessels operating within their jurisdiction. The calculations contained herein were based on the client request to Rerate the vessel to 25psig at 200 F. A corrosion allowance was established to meet MDMT requirements without impact testing and to extend the life of the vessel for greater than 20 years at the present estimated corrosion rate. All conditions appear to be satisfactory for the proposed Rerate of the Railcar ACAX 80005.

3 Rerate must be performed in accordance with the latest revision of the National Board (NB) by a contractor that is a NB certified R stamp holder for repairs of pressure vessels. A Rerate nameplate must be install on the vessel and the PSV must be reset to 25psi maximum for over pressure protection of the ReferenceMAWP 25psiTemp No ReferenceTemp 200'FMDMT No ReferenceMDMT-20'FCa No ReferenceCa "Hydro Test Orig400psiHydro Test 33psiRerate change from original designRerate change from original designEvaluation ASME S8 D1.
