Pressure Relief Valve Testing Checklist [FREE PDF]

Pressure relief valves (PRVs) are the last line of defense against catastrophic over-pressurization events in oil and gas facilities, making their testing and maintenance a cornerstone of process safety management. OSHA 29 CFR 1910.119 PSM Standard mandates a written mechanical integrity program that includes regular inspection, testing, and documentation of all PRVs in covered processes. API Standards 520 and 521 provide the industry-recognized engineering basis for PRV sizing, selection, insta

  • Industry: Oil & Gas

Pre-Test Verification & Isolation

Confirm safe isolation, permit authorization, and documentation review before testing begins.

  • Has a valid Permit to Work (PTW) been issued and signed by all required parties?
  • Has the PRV been properly isolated from the process and depressurized to a safe level?
  • Has the previous PRV test record and set pressure been reviewed prior to this test?
  • Has the PRV nameplate data (set pressure, capacity, model) been verified against P&ID and relief load study?
  • Is calibrated test equipment available and within current calibration date?

Physical Condition Inspection

Examine the PRV body, bonnet, discharge piping, and external components for physical defects.

  • Is the PRV body and bonnet free from visible corrosion, pitting, or mechanical damage?
  • Are all bolted flange connections on the PRV inlet and outlet free from leaks or corrosion?
  • Is the PRV discharge piping properly supported and routed to a safe discharge location?
  • Is the PRV inlet block valve (if installed) locked open and tagged?
  • Has a photo of the PRV nameplate and general condition been captured?

Set Pressure Testing

Perform and document the PRV set pressure test using an approved test bench or in-situ method.

  • Was the PRV tested on a certified test bench or using an approved in-situ testing device?
  • What is the recorded actual set pressure (pop pressure) measured during testing (in psig)?
  • Is the measured set pressure within the allowable tolerance of the nameplate set pressure?
  • Did the PRV lift and reseat cleanly without chatter, flutter, or sticking?
  • Was the blowdown (difference between set and reseat pressure) within acceptable limits?

Internal Component Condition

Document the condition of internal components including disc, nozzle, seat, and spring.

  • Is the valve disc (or piston) free from scoring, corrosion, or deformation?
  • Is the nozzle seat free from wire-drawing, pitting, or corrosion damage?
  • Is the main spring free from corrosion, cracking, or deformation?
  • Are the guide and body bore free from buildup, fouling, or corrosion?
  • Is a rupture disc installed upstream of this PRV?

Seat Tightness & Leakage Assessment

Evaluate seat tightness and document any evidence of prior leakage.

  • Did the PRV pass the seat tightness test after reseat (no audible or visible leakage)?
  • Is there evidence of prior seat leakage (e.g., staining, deposits, corrosion on outlet piping)?
  • Is the bonnet vent or weep hole on the PRV clear and unobstructed?
  • For balanced bellows PRVs, is the bellows intact with no evidence of failure or process fluid in the bonnet?
  • Has the PRV outlet and tail pipe been inspected for blockage or liquid accumulation?

Repair, Adjustment & Recertification

Document any repairs made, adjustments to set pressure, and recertification of the PRV.

  • Were any internal components replaced during this service interval?
  • If components were replaced, were OEM-specified or equivalent replacement parts used?
  • Has the PRV set pressure been adjusted and verified to match the required design set pressure?
  • Has a new lead seal or tamper indicator been applied after testing and adjustment?
  • Has a new PRV test tag been attached with the test date, set pressure, and next test due date?

Reinstatement & Final Sign-Off

Confirm safe reinstatement to service, documentation completion, and inspector sign-off.

  • Has the PRV been reinstalled per the approved work order and P&ID configuration?
  • Has all isolation been removed and the PRV returned to its normal in-service position?
  • Has the completed test record been entered into the plant maintenance management system?
  • What is the recommended next PRV test date based on service history and regulatory requirements?
  • Please record any additional observations, anomalies, or recommendations for this PRV.
