Pneumatic Testing

Precision Pressure Verification

Pneumatic testing uses air or inert gas such as nitrogen to verify the integrity and leak-tightness of pipelines and pressure vessels. Unlike hydrostatic testing, it is suitable for systems where water contact is prohibitive or for detecting very small leaks.

Velcorix conducts these high-risk tests with meticulous planning, exclusion zones, and remote monitoring to ensure absolute safety and compliance with ASME/API standards.

Scope / What’s Included

Nitrogen Testing

High-purity leak testing for process systems sensitive to moisture.

Air Pressure Tests

Compressed air testing for instrument air lines and utility piping.

Helium Leak Detection

Trace gas detection for identifying microscopic leaks in flange joints.

Reinstate & Purge

Safe depressurization and inerting of systems post-test.

Typical Real-World Applications

Gas Pipelines

Testing of transmission lines where hydrotesting is not feasible.

Cryogenic

Testing LNG lines which must remain absolutely dry.

Instrument Air

Verifying control system tubing and manifolds.

Vessels

Low-pressure integrity checks on storage tanks.
