Pneumatic Testing: Process Piping Applications

Pneumatic testing verifies pressure integrity using air or another approved test medium instead of water. Primus applies pneumatic testing where moisture is not acceptable, where hydrotest water could damage internal surfaces or coatings, where added water weight is a concern, or where post-hydrotest drying would create schedule or quality problems.

Where It Applies

Industrial & Municipal Applications

Industrial / Oilfield Applications

Because pneumatic testing stores significantly more energy than hydrotesting, Primus treats every pneumatic test as a safety-first exercise: planning stored-energy considerations, defining test boundaries and isolation points, setting exclusion zones, securing code or client engineering approval, and executing with pressure monitoring, leak checks, and a clear communication plan. Primus positions itself as a practical field-execution partner for pneumatic testing planning and delivery, not as a shortcut around proper engineering approval.

Typical Applications

  • Process piping leak testing
  • Pre-commissioning
  • Plant modifications
  • Prefabricated piping systems
  • Utility air systems
  • Instrument air systems
  • Sensitive piping systems
  • Situations where introducing water is not practical or desirable

How We Deliver It

Field Execution & Documentation

Typical Equipment & Field Setup

  • Calibrated pressure gauges and recorders
  • Compressors or nitrogen supply as required
  • Isolation and vent valves
  • Leak-detection equipment
  • Barricading and exclusion-zone signage

Planning Considerations

  • Engineering approval and stored-energy calculations before mobilization
  • Test boundaries and isolation points
  • Exclusion-zone sizing based on stored energy
  • Step-wise pressurization plan
  • Communication protocol between test crew and site

Safety & Compliance Considerations

  • No execution without engineering/code approval
  • Strict exclusion zones sized to stored energy
  • Step-wise, monitored pressurization
  • Qualified, competent crews only
  • Documented go/no-go checkpoints throughout the test

Deliverables & Documentation

  • Approved test procedure on file
  • Pressure and hold-time records
  • Leak-check results
  • Sign-off documentation for client and regulatory records
