Answers to Critical Concerns

Frequently Asked Questions

Common questions about our nitrogen service standards and deployment approach.

We supply nitrogen at purities up to 99.999% depending on application requirements. Standard purging operations typically use 95-99% purity, while sensitive applications like oxygen-line displacement require ultra-high purity grades.

Yes. Pneumatic testing with nitrogen is performed per ASME B31.3, B31.4, and CSA Z662 standards. It is preferred where hydrostatic testing is impractical due to system design, temperature, or water-sensitivity concerns.

Pipe freezing uses liquid nitrogen to create a solid ice plug inside a water-filled pipe, providing temporary isolation for valve replacements, tie-ins, or repairs without draining the entire system.

Cool-down rates depend on system volume, wall thickness, and target temperature. Typical applications achieve 50-100°C per hour reduction. We engineer the flow rate and injection points to prevent thermal shock.

Yes. We use helium mass spectrometry combined with nitrogen carrier gas to detect leaks as small as 1×10⁻⁶ cc/sec, suitable for critical flanges, valve packing, and weld joints.

Our fleet ranges from small high-pressure bottle banks for localized work to bulk liquid nitrogen tankers and high-flow gasification units capable of sustained flow rates exceeding 5000 scfm.

Absolutely. Nitrogen is frequently paired with chemical cleaning (for pre/post purging), pipeline pigging (displacement medium), and pre-commissioning activities (drying and preservation).

In most Canadian and US jurisdictions, regulatory requirements mandate inerting of pipelines containing or having contained flammable products before cutting, abandonment, or safe venting. We ensure compliance with all applicable codes.
