THE PROBLEM YOU'RE SOLVING

Hidden Leaks Compromise System Safety and Performance

System Failures

Undetected leaks in gas distribution systems cause pressure drops, contamination, safety hazards, and production failures. Testing before system operation prevents costly repairs and dangerous situations.

Compliance Requirements

Regulatory standards and commissioning procedures require documented pressure testing before introducing process gases. Missing this critical step risks system failure and compliance violations.

The Solution

Comprehensive pressure testing identifies gross leaks quickly using nitrogen or compressed air, verifying system integrity before fine leak detection methods like helium testing. This two-stage approach saves time and ensures thorough verification.

WHAT IS PRESSURE TESTING?

Essential First-Stage Verification for Gas Systems

Pressure testing verifies the structural integrity and leak-tightness of piping distribution systems by pressurizing with nitrogen or compressed air and monitoring for pressure loss over time. This non-destructive testing method identifies gross leaks quickly and cost-effectively, serving as the essential foundation before fine leak detection.

Why Pressure Testing Matters

Cost-Effective Leak Detection

Identifies major leaks quickly without expensive specialized equipment. Repairs gross leaks before investing in sensitive helium leak testing.

Safety Verification

Confirms piping can safely contain process gases at operating pressures. Prevents catastrophic failures from weak joints or defective components.

Regulatory Compliance

Provides photographic and video evidence of internal conditions for quality records. Audit-ready documentation for regulatory compliance.

Foundation for Advanced Testing

Essential prerequisite before helium leak testing. Systems must pass pressure testing before fine leak detection methods are applied.

INDUSTRIES & APPLICATIONS

Critical Testing Across High-Pressure Gas Systems

Essential integrity verification for industries where system failures cause safety hazards and production losses

Semiconductor Manufacturing

Why Pressure Testing Matters: Semiconductor gas distribution systems operate at precise pressures to deliver ultra-high purity gases. Pressure testing verifies system integrity before introducing expensive specialty gases and prevents contamination from atmospheric intrusion.

Why Pressure Testing Matters: Industrial gas distribution networks operate under high pressures with hazardous materials. Pressure testing ensures safety-critical system integrity before gas introduction.

Critical Applications:

  • Bulk Gas Distribution: Nitrogen, oxygen, argon, helium delivery systems
  • Tank Farm Piping: High-pressure piping from storage to distribution
  • Process Gas Networks: Manufacturing facility gas distribution systems
  • Pipeline Installations: New construction and repair verification

WHEN YOU NEED PRESSURE TESTING

Critical Testing Scenarios for System Integrity

Schedule pressure testing at these key milestones before system operation

New Facility Commissioning

Qualify all gas distribution systems before introducing process gases. Required first step before helium leak testing and system startup.

Post-Installation Verification

Confirm leak-free integrity after new piping installation. Essential verification before system energization.

Post-Welding Qualification

Verify weld integrity following new construction or repairs. Identifies defective welds before advanced testing.

System Modification Testing

Re-verify integrity following valve replacements, piping additions, or system expansions. Ensures modifications didn't introduce leak paths.

Pre-Helium Leak Testing

Required prerequisite before helium mass spectrometer leak testing. Identifies gross leaks cost-effectively before expensive fine leak detection.

Periodic Recertification

Annual or periodic re-verification per safety protocols. Maintains documented proof of system integrity.

Troubleshooting Investigations

Identify source of pressure loss or suspected system leaks. Systematic approach to locate problem areas.

Emergency Response

24/7 rapid response for suspected system failures. Minimize downtime with immediate integrity verification (subject to availability, <3 hour mobilization).

FREQUENTLY ASKED QUESTIONS

Pressure Testing FAQs

What test pressure should be used?
Typical test pressure is 110% of maximum operating pressure, but may vary based on client specifications, system design codes, and regulatory requirements. We review your system specifications during pre-test consultation to determine appropriate test pressure.

Duration varies by system size and hold period requirements. Typical testing:  4-24 hours for small systems and large distribution networks. Hold period specified by client requirements or industry standards.

Pressure testing identifies gross leaks quickly and inexpensively. Repairing these major leaks before helium testing saves time and cost, as helium leak testing is designed for fine leak detection, not gross leaks.

We use nitrogen or compressed air, depending on system requirements and client specifications.

No. Pressure testing requires system isolation and shutdown. Systems must be empty and isolated from process gases during testing.
Testing frequency depends on industry requirements and system criticality. Semiconductor: after installation, modifications, and per annual safety protocols. Industrial: per regulatory requirements.
Yes. Every test includes comprehensive documentation: test reports with pressure data, P&ID drawings, equipment calibration certificates, inspector certifications. All documentation is audit-ready.
We document leak locations and severity. After repairs, we re-test the affected areas to verify leak-free integrity. Complete documentation provided for all findings and re-tests.
