Frequently Asked Questions

What standards govern pressure vessel fabrication in Alberta?

Pressure vessel fabrication in Alberta must comply with ASME Section VIII, ASME Section IX, and CSA B51 requirements. Contractors must also be certified by the Alberta Boilers Safety Association (ABSA) to fabricate, alter, or repair pressure vessels and components.

What is the difference between pressure vessel repair and alteration?

Pressure vessel repair restores equipment to its original design, while alteration modifies vessel components to meet new process conditions or higher pressures. Both must follow ASME Section VIII and ABSA regulations to ensure safety and compliance.

Do you provide shop and field repairs for pressure vessels?

Yes. WLMG offers both shop and field repairs for pressure vessels and components, including welding, component replacement, and non-destructive testing. Our certified team ensures all repairs meet regulatory standards and maintain vessel integrity.

Can you fabricate custom pressure vessels for oil and gas projects?

Yes. WLMG specializes in custom pressure vessels and equipment for oil and gas and industrial applications. Our team of certified fabricators delivers vessels that meet ASME codes, National Board (NBIC) standards, and client-specific design requirements.
