High-Pressure Piping in Quebec City: The Requirements
August 28, 2025 5 min read
High-pressure piping demands careful preparation, the right WPS and inspection before pressure testing. Here is what it takes in Quebec City.
Preparation sets up everything else
On a high-pressure line, weld quality starts with preparation. The bevels, alignment, gap and adherence to the WPS parameters determine how the joint holds up under pressure. A bad prep shows up later — as a leak or a rework call.
The process is chosen by diameter and wall thickness: GTAW for the root pass, FCAW or SMAW for fill.
Heavy-wall steel and aluminum
Heavy-wall carbon steel pipe is common in high-pressure service. Aluminum shows up in nitrogen and industrial-gas plants, where weight and corrosion resistance matter. Each material calls for its own WPS and filler metal.
Inspection before pressure testing
Before pressure testing, welds are identified, inspected and traced. Coordinating with your inspector or team lets you plan the tests the service requirements call for.
