About this file
This is an Annual Inspection Checklist for Unfired Pressure Vessels used as a template for external inspection evaluations. The checklist provides a standardized format for inspectors to systematically assess the condition and operational integrity of pressure vessels through a series of yes/no items and observations.
The checklist covers comprehensive external inspection criteria including evaluation of insulation and coatings, bolts and fasteners, vessel mountings, structural integrity (cuts, gouges, distortion), welded joints and heat-affected zones, flange faces, surfaces for erosion or dents, and connections such as manholes, reinforcing plates, and nozzles. Additional inspection items address leakage detection, thread engagement on connections, obstruction-free openings, high-stress concentration areas, verification that set pressure does not exceed maximum allowable working pressure (MAWP), and proper condition and operation of pressure gauges and relief valves. The checklist includes fields for vessel identification, inspector signature, inspection date, and comments. This template is directly applicable to the Department of the Army's solicitation W51AA126QA090 for Unfired Pressure Vessel Inspections, which requires contractors to perform base-year structural integrity inspections followed by annual external visual inspections over four option years on a firm fixed-price basis.
