Welding (CSA W47.1)

• W47.1 Division: 3 Scope: Custom steel fabrication, repairs, revamp and modifications for structures and lifting device attachments and components.
• Division: 2 Scope: Structural steel fabricator. Installation and repair of structural steel for the power generation, pulp and paper, offshore oil and gas, and the petro chemical industries.

Pipefitting

• Steam Trace
• Valves, PSV install, replacement
• Spool replacement (non scaffold)

Steam trace repairs are conducted on assets such as pipelines, towers, vessels, structures and even supply and trap headers. Acuren has built a strong working relationship with many of the process operators and, in doing so, makes for a more efficient work environment for tracking leaks, potential hazards and potential hazardous areas for ice build-up in the winter months. One of the key elements in our success for eliminating the steam trace leaks is the versatility and ability to move through the units and pipe racks with ease. In many cases we are called in to fix an isolated section where a leak is located and once that leak has been fixed, it can reveal more leaks or failures further down the line once the pressure is restored. Fixing of these new as-founds leaks is conducted swiftly using Acuren services without scaffold modifications or change orders, we can move down the line and continue working without interruption.

Typical work scopes, all of which could be done via rope access, could include:

• Patches on live equipment
• Work over live equipment otherwise inaccessible
• Field fitting and welding spools / flanges
• Repairs over live equipment
• Wear liner repair / replace
• Overlay / hard surfacing repairs
• Nozzle repairs
• Structural repairs
• Cleaning and installation of air movers
• Provide pipe fitting procedures
• Assist in isolation of equipment
• Replace spring hangers

Our teams can handle even the most complex projects, some of which include:
