Procurement of Equipment that Contains Pressure Vessels or Pressure Relief Devices

  • John Miller
Lessons Learned

The procurement of equipment that contains pressure vessels or pressure relief devices can be a source of problems upon receipt of the equipment.


An arc/induction melter was procured as an “off the shelf” item. A number of pressure protection compliance problems were discovered after receipt. These problems included a pressure relief valve with a set pressure that exceeded the stamped maximum allowable working pressure (MAWP) of the protected vessel, insufficient number of pressure relief devices (PRDs), and no vendor calculations to support the sizing and selection of vendor supplied PRDs.

Attached is a checklist of useful items to consider when preparing a procurement requisition for equipment involving pressurized components.
