Plant Shutdowns and Turnarounds

Shutdowns run on tight windows. We plan ahead with your maintenance team so pipe modifications, repairs and tie-ins are ready to go the moment the system is down, then help get the plant back online on schedule.

B Pressure Welding FAQ

What is B pressure welding?

It is welding on pressure piping and pressure equipment, such as process lines, steam systems, boilers and vessels, done by certified B Pressure welders. In Alberta this work falls under the Safety Codes Act, with ABSA overseeing pressure equipment.

Can you help during a scheduled shutdown?

Yes. Scheduled shutdown welding is part of our plant support, along with emergency pressure system repairs, pipe modifications, upgrades and retrofits.

Do you weld in the shop or in the field?

Both. We offer mobile and in-shop welding, so spools and assemblies can be fabricated in our Calgary shop and tie-ins done on site.

What can you fabricate in the shop?

Pipe spools, manifolds, reducers, flanges and connections, custom pipe assemblies, and stainless steel and alloy components.
