Our Leak Sealing Process
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
Using data from your field personnel or third-party providers, we develop accurate 3D models of your equipment to replicate real-world conditions. These models form the foundation for designing custom-fit Engineered Pressure Enclosures (EPEs) that ensure precise fit and reliable performance.
Sources of Measurement Data:
- Hand Measurements: We recreate equipment geometry from field sketches and measurements, capturing all critical dimensions and nearby obstructions.
- 3D Scanning: When laser scan data is collected using a 3D scanner such as the Artec Leo or similar systems, we convert the point cloud data into precise 3D models, capturing complex geometries and surface details.
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 will receive a complete, P.Eng.-stamped Engineering Design Package containing all documentation required for fabrication, verification, and regulatory submission. Each package includes:
- General Assembly and Fabrication Drawings – Clearly detailed to support accurate manufacturing and installation.
- Engineering Analysis and Calculations – Complete design validation in accordance with applicable codes and standards.
- 3D Model Files – Fully detailed digital models of the Engineered Pressure Enclosure (EPE) to streamline manufacturing and quality assurance.
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
Tongue & Channel Clamps
These clamps seal leaks at flanged joints caused by damaged or compromised gaskets and seals. Tongue clamps use a machined tongue to fit into the flange gap, allowing sealant to be injected directly into the joint. They are effective for most flanged joints and especially useful for misaligned flanges. Channel clamps seal around the outer edge of the flange, making them ideal for narrow gaps where a tongue clamp cannot be used.
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 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 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 machined and weld-prepped for on-site and live welding installation.
Strongbacks
Strongbacks reinforce compromised systems by countering separation forces and preventing equipment failure. They’re especially valuable when dealing with degraded bolting, damaged threads, weakened or corroded components, or welds at risk of failure. This adds a vital layer of protection for mechanical integrity, safety, and leak containment.

FAQs
What is on-line leak sealing?
It’s a process that seals leaks in pressurized systems without stopping operation—no shutdown required.
What types of leaks can be sealed?
- Leaking gaskets or gasket failures
- Leaking flanges
- Elbow leaks
- Leaking valves
- Threaded joint leaks
- Thinning or corroded pipes
- Weld porosity or pinhole leaks
Are there regulations governing leak sealing?
There’s no single global standard, but work is usually carried out under:
- API standards
- ASME codes
- 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.
Is it cost-effective?
Yes. Avoiding shutdowns can save millions in production losses, especially in continuous process industries.
Does it provide a permanent fix?
Often it is temporary or semi-permanent, buying time until a planned shutdown. However, some EPEs can last for years.
How quickly can you respond to a leak?
You can reach us easily, and once all the necessary information is collected, designs are typically completed within 1 to 4 business days, depending on the complexity. We understand the urgency our clients face and are committed to providing accurate and reliable design timelines to support effective planning.
