Our Leak Sealing Services

  • Leak Assessment & Consultation

    Our process begins with a detailed assessment of your system, including:

    Leak location and severity

    Operating conditions (pressure, temperature, and media)

    Design requirements for safety, compliance, and performance

    Applicable regulatory codes and jurisdictional standards

  • 3D Modeling of Your Equipment

    Based on data provided by your field personnel or third-party service providers, we create precise 3D models of your equipment to accurately reflect real-world conditions. These models form the foundation for designing custom-fit Engineered Pressure Enclosures (EPEs) that ensure optimal performance and reliability.


    Sources of Measurement Data:

    Hand Measurements: When detailed sketches and field measurements are provided, we recreate the equipment geometry, capturing critical dimensions and nearby obstructions. We also provide guidance on the data collection needed to support accurate modeling.

    3D Scanning: When laser scan files (e.g., from Artec Leo or similar systems) are provided, we process the point cloud data into accurate 3D models. This allows us to capture complex geometries and assess surface irregularities, ensuring a precise fit and streamlining enclosure design.

  • Custom EPE Design & Analysis

    Every Engineered Pressure Enclosure (EPE) is custom-designed to your system’s exact requirements. We ensure full compliance with all applicable codes and standards, including:

    CSA B51

    ASME BPVC Section VIII Division 1

    ASME B31.1 and B31.3

    ASME PCC-2

    ABSA AB-521

  • Engineering Design Package

    You’ll receive a complete, P.Eng.-stamped design package, including:

    General assembly and fabrication drawings

    Engineering analysis and calculations

  • CRN Application & Pressure Authority Submissions

    We handle the entire CRN (Canadian Registration Number) process on your behalf. From start to finish, we ensure smooth, efficient submissions to the appropriate regulatory body in your jurisdiction, including:

    ABSA – Alberta Boilers Safety Association

    TSSA – Technical Standards and Safety Authority (Ontario)

    TSBC – Technical Safety BC

    ACIC – ACI Central (for select provinces/territories)

    TSASK – Technical Safety Authority of Saskatchewan 

Common Leak Sealing Solutions

We engineer a wide range of Engineered Pressure Enclosures (EPEs) to safely seal active or potential leaks across various components and conditions. Each design is custom-tailored to your equipment, operating environment, and compliance requirements.

  • Leaking Sealing Tongue Clamp

    Tongue & Channel Clamps

    Designed for flanged joints, these clamps seal leaks originating from gaskets or raised faces.

    Tongue Clamps feature a precisely machined tongue that fits into the gap between flanges. Sealant is injected through dedicated ports to fill the flange cavity and stop the leak. This solution is ideal when:

    The flange gap is large enough to accommodate the tongue

    Flanges are misaligned or uneven

    Channel Clamps seal around the outer edge of the flange, making them a better fit when the gap is too narrow for a tongue clamp.

  • Bolt-On Enclosures

    Used on a wide range of components including pipes, elbows, tees, and valves, bolt-on enclosures offer a flexible and reliable solution. They can be customized with various sealing methods and design features to suit your preferences and system’s pressure, temperature, and media

  • Leak Sealing Plate box Images

    Plate Box Enclosures

    Machined from solid plate, this two-piece bolted enclosure is a robust and time-efficient solution. The internal cavity, sealing surfaces, and bolt holes are precision-machined, making this option cost-effective due to its straightforward fabrication process for many applications.

  • Welded Enclosures

    Constructed by welding together shells, nozzles, lugs, and end plates before machining, welded enclosures are ideal for larger components where plate box enclosures are no longer practical, or where a lighter enclosure is needed compared to solid plate box designs.

  • Weld-On Enclosures

    These permanent, field-welded enclosures are ideal for high-vibration environments, significant thermal cycling, or when long-term durability is essential. Typically built in two halves, they are precision-machined and weld-prepped for on-site and live welding installation.

  • Strongbacks

    Strongbacks provide mechanical reinforcement to compromised systems, countering separation forces and preventing equipment failure. They’re especially useful when dealing with:

    Suspect or degraded bolting hardware

    Damaged threaded connections

    Weak or corroded pressure components

    Welded joints at risk of failure

    Strongbacking adds a critical layer of protection in systems where mechanical integrity is uncertain, supporting both operational safety and leak containment success.

    • Local/regional pressure vessel regulations

    • Internal company standards

    All our designs follow applicable codes (ASME, CSA B51, etc.) and are stamped by a licensed professional engineer.

  • Yes. Avoiding shutdowns can save millions in production losses, especially in continuous process industries.


  • Often it is temporary or semi-permanent, buying time until a planned shutdown. However, some EPEs can last for years.
