Piping Pre-Commissioning Checklist

A Piping Pre-Commissioning Checklist helps ensure that all piping systems are properly prepared, tested, and ready for commissioning. Using a digital tool like eAuditor Audits & Inspections  can streamline this process, allowing for easier documentation, tracking, and verification of tasks. Below is a detailed Piping Pre-Commissioning Checklist that can be implemented using eAuditor Audits & Inspections.

Piping Pre Commissioning Checklist

Piping Pre-Commissioning Checklist Template


General Information

  1. Project Name:
  2. Location:
  3. Piping System Type: (e.g., water, gas, oil, etc.)
  4. Inspector Name:
  5. Date:
  6. P&ID Drawing Number:
  7. System Identification Number:
  8. Pipe Material: (e.g., carbon steel, stainless steel, etc.)

1. Documentation Review

  • P&ID Verified: Check that Piping & Instrumentation Diagrams (P&IDs) are current and match the physical piping layout.
  • Isometric Drawings: Ensure to use approved isometric drawings and match the installed piping.
  • Valve List Verified: Confirm all valves installed as per the approved valve list.
  • Test Procedures Available: Verify that all necessary test procedures are available and approved.

2. Visual Inspection

  • Piping Material Verification: Confirm the piping material matches project specifications.
  • Flange Joints: Inspect flange joints for proper bolting, gasket installation, and cleanliness.
  • Pipe Supports: Ensure the installation of  all pipe supports is as per design and is free from defects.
  • Weld Inspection: Verify the completion, inspection and documentation of all welds.
  • Corrosion Protection: Confirm all piping and supports are coated or treated for corrosion prevention (where applicable).
  • Cleanliness Check: Ensure the piping system is clean from debris, welding slag, and foreign objects.
  • Insulation and Painting: Verify the completion of insulation and painting work.

3. Leak Testing (Hydrostatic / Pneumatic)

  • Confirm Test Pressure: Ensure to calculate correct test pressure.
  • Test Medium Confirmed: Confirm the medium to be used (e.g., water, air, nitrogen, etc.).
  • Gauge Calibration: Verify the calibration of pressure gauges and valid certification.
  • Test Witnessed: Check that all relevant parties are present to witness the test.
  • Pressure Maintained: Ensure that the required pressure is maintained for the specified duration without leaks.
  • Test Results Recorded: Document and store the results of the leak test.
  • Ventilation Check (for Pneumatic): Ensure proper ventilation and safety measures are in place during pneumatic testing.

4. Flushing and Cleaning

  • Flushing Plan in Place: Confirm the approval of flushing plan and alignment with the system requirements.
  • Installation of Temporary Strainers : Verify the installation of  temporary strainers for flushing (where applicable).
  • Monitor Flow Rate : Ensure to monitor flow rate during flushing and make sure it is sufficient.
  • Debris Removed: Confirm the removal of all debris from the system post-flushing.
  • Maintain Flushing Records: Ensure to document all flushing activities and maintain all records.

5. Pressure Relief Devices

  • Install Safety Valves: Ensure the installation of pressure relief valves or safety devices.
  • Calibration Certificates: Verify that calibration certificates for all pressure relief devices are available.
  • Set Points Verified: Confirm that set points for pressure relief valves match the system requirements.

6. Final System Integrity Checks

  • Final Torqueing of Bolts: Confirm all bolts are torqued according to the approved torque specification.
  • Valve Position Verification: Ensure all valves are in the correct operating position (open/close).
  • Instrument Calibration: Verify that all connected instruments (pressure gauges, flow meters, etc.) are calibrated and functioning correctly.
  • Piping Tagged: Confirm that all piping is tagged and labeled per project specifications.
  • Completion of Punch List Items: Ensure all punch list items related to the piping system are completed and signed off.

7. Safety Checks

  • Work Area Cleared: Verify that the work area is free from unnecessary equipment or obstructions.
  • Lockout/Tagout Procedures Followed: Ensure to follow lockout/tagout procedures for system isolation during testing.
  • Signage Installed: Check that all necessary safety and warning signs are installed.

8. Approvals and Sign-Offs

  • Inspection Completed By:
  • Inspector Signature:
  • Client/Owner Representative Name:
  • Client/Owner Signature:
  • Date of Final Approval:

Using eAuditor Audits & Inspections for Piping Pre-Commissioning

  1. Create the Template: Input the checklist into eAuditor Audits & Inspections using the template builder. Customize fields to make them more interactive (e.g., yes/no checkboxes, photo capture, signature fields, etc.).
  2. Assign Inspections: Assign the checklist to appropriate team members or inspectors who will perform the pre-commissioning activities.
  3. Real-Time Reporting: With eAuditor Audits & Inspections, you can generate real-time reports, upload photos, and add notes directly from the app. This provides immediate feedback and documentation.
  4. Monitor Compliance: Track progress through eAuditor Audits & Inspection’s analytics to monitor the completion of tasks, identify outstanding issues, and ensure compliance with pre-commissioning protocols.
  5. Generate Reports: Export inspection reports in PDF format or share them digitally with stakeholders for final approval.
