Underground Ventilation Piping by Patrick Mechanical

How PML’s Certified Ventilation Solutions Keep Mining Operations Safe and Compliant

Underground mining demands mechanical systems that are not only durable, but also built with strict compliance and safety in mind. At Patrick Mechanical Ltd., we specialize in custom piping solutions for underground ventilation, fabricated, installed, and inspected to meet the highest standards.

With over three decades of experience and multiple TSSA-authorized certifications, we ensure every vent pipe system we deliver is code-compliant, safe, and built to last.

Precision Built for Demanding Conditions

Mining environments are harsh. Ventilation systems must effectively manage airflow, removing harmful gases while supplying fresh air to underground teams. If air movement fails, productivity suffers—and more importantly, lives are at risk.

At PML, we design and fabricate custom vent piping systems tailored for these conditions. Our work is certified under TSSA BPV Certification QA-01700 for Power Piping Installation (ASME B31.1), which covers both shop and field fabrication. This ensures every weld, joint, and segment is crafted to strict technical and safety requirements.

We don’t just meet code—we build with the expectation that lives depend on it. Because in many cases, they do

Efficient Installation with Minimal Downtime

Installing power piping in an active mine is complex. Space is limited. Operations can’t stop. That’s why our team works closely with project managers and site leads to plan efficient installations that minimize disruption.

We prefabricate key components in our Sudbury-based shop, using a certified alternate inspection process (TSSA QA-10554) to streamline project timelines without compromising quality. This proactive approach allows us to deliver faster, safer installations that reduce downtime and keep your schedule intact.
