Underground High Pressure Dewatering Piping

Reliable Process Piping for Industrial and Mining Sites

In mining, industrial, and energy operations, process piping is more than infrastructure, it’s the backbone of your operation. When systems fail, it’s rarely just a pipe issue. It’s production loss, safety risk, and compliance exposure. At Patrick Mechanical Ltd., we specialize in custom-built, high-performance process piping systems that hold up under pressure, literally and operationally.

What Is Process Piping, and Why Does It Matter?

Process piping is the network that moves fluids, gases, slurries, or chemicals through industrial systems. Whether it’s high-pressure dewatering, chemical transport, or glycol cooling loops, these systems need to do more than connect Point A to Point B. They need to:

  • Handle abrasive or corrosive materials
  • Maintain pressure and temperature control
  • Comply with codes, CRN requirements, and inspection standards
  • Integrate with existing equipment and systems
  • Be built for performance and safety

That’s where many systems fall short, and where we stand apart.

Common Pitfalls in Industrial Piping Projects

Many process piping failures stem from the same underlying problems:

  • Generic system designs that ignore site-specific flow demands
  • Low-grade materials that corrode or degrade under pressure
  • Disconnected contractors across design, fabrication, and install phases
  • Inadequate inspection or traceability, leading to compliance and QA issues

Once operational, those gaps can turn into shutdowns, injuries, or even code violations. That’s why it’s essential to work with a contractor that understands the full lifecycle of process piping, from engineering and material selection to QA/QC and field installation.

Our Approach: Custom, Compliant, and Coordinated

Patrick Mechanical Ltd. provides end-to-end process piping solutions built on decades of experience in Northern Ontario’s most demanding industries.

We offer:

Custom Design and Engineering

Our team supports 2D drafting, 3D CAD models, and design reviews to align with your system needs, space constraints, and code compliance, including CRN-certified designs.

Certified In-House Fabrication

We fabricate piping in a controlled environment using carbon steel, stainless steel, and specialty alloys. Welders are CWB certified and experienced in MIG, TIG, and SMAW across a range of applications.

Quality Assurance and Traceability

We apply strict QA/QC procedures including material tracking, weld mapping, and inspection documentation. NDE testing (VT, PT, UT) is performed as needed, with all results recorded for client transparency and compliance.

Field Installation and Commissioning

Our teams handle everything from rigging and layout to on-site welding, tie-ins, and final testing. We also manage hydro testing, oxygen cleaning, and system commissioning to ensure everything performs as intended, before it ever goes live.

Built for the Realities of Mining and Industry

We’ve delivered piping systems for:

  • Underground mine dewatering systems
  • Chemical feed and process systems
  • Pressure-rated steam and gas lines
  • Cooling and heating loops
  • Waste and dust collection lines

From custom skids to full plant piping installs, we understand the regulatory, environmental, and operational demands of your site. And we build with that in mind from day one.

Let’s Build It Right—The First Time

If you’re planning a new piping system, or dealing with one that’s failing to meet expectations, we’re here to help. At Patrick Mechanical, we don’t just build piping. We build reliability.
