Industrial and High-Pressure Pipe Fabrication and Welding in Laval and Across Quebec
From shop prefabrication to on-site installation, we build industrial and high-pressure piping assemblies that match the isometric drawings and the service requirements.
Industrial and High-Pressure Pipe Fabrication and Welding
Prefabrication and welding of industrial and high-pressure piping in carbon steel, stainless steel, aluminum and alloys, from isometric drawings to on-site commissioning.
Shop prefabrication
Shorter field schedules through prefabrication of spools and assemblies in a controlled shop environment.
All alloys
Carbon steel, stainless steel, duplex, copper-nickel and special alloys, welded with qualified procedures.
High pressure
Heavy-wall tube welding and aluminum piping for nitrogen and industrial gas plants.
Quality control
Visual inspection, weld traceability and compliance with ASME IX and CWB requirements.
Commissioning
Installation, alignment and startup of the systems, through to return to service of the line.






Industrial and High-Pressure Pipe Fabrication and Welding: what you should know
Industrial pipe fabrication and welding covers the full production cycle of a piping system, from reading the isometric drawing to commissioning the line in the plant. For a plant manager or project engineer, the main upside of shop prefabrication is less time spent in the production area: spools are welded, inspected and marked in a stable environment, then shipped to site for quick assembly. Caro Groupe Industriel structures its projects around this logic to compress shutdown windows and cut down on improvisation in the field.
The quality of a piping system depends as much on preparation as on welding. Every joint is prepped, aligned and welded to a qualified welding procedure specification (WPS) backed by ASME IX and CWB 47.1 qualifications. Our welders work carbon steel, 316L stainless steel, duplex, super duplex, copper-nickel and special alloys such as Monel and Inconel. Weld traceability, spool identification and systematic visual inspection deliver an installation that meets the client's requirements and the applicable standards.
High-pressure pipe welding goes beyond the weld bead. Bevel prep, fit-up, gap control and following the WPS parameters are what make a joint hold under pressure. Our ASME IX qualified welders work carbon steel, stainless steel, aluminum and heavy-wall alloys, where weight and corrosion resistance matter. Every weld is identified and traced for the inspection and documentation the client requires.
From our shop in Laval, we serve Montreal, Quebec City, Trois-Rivières, Sorel-Tracy and the rest of Quebec. The proximity of industrial parks and processing plants keeps logistics tight between the shop and the site. We build the fabrication sequence around access limits, available lifting equipment and the plant's production schedule. This approach serves industrial construction and plants as well as petroleum-industry facilities, where piping compliance is critical. New process line, modification of an existing system or equipment replacement — we send a detailed quote and a clear plan of work up front. Reach out to talk through your industrial piping project.
