Mobile Pipe Welding
- SMAW, GTAW, and GMAW processes
- On-site — no equipment transport
Power piping is the highest-consequence work we do, and it is where certification and documentation stop being paperwork and start being the whole point. We hold TSSA certificate QA-01697 for ASME B31.1 power piping installation and QA-01699 for boiler and pressure vessel repair and alteration. Every joint is completed by a welder qualified for that procedure, with records available for your files and your inspector.
B31.1 is the ASME code governing piping in power generating stations, industrial plants and district and central heating systems — boiler external piping, high-pressure steam and hot water, and the connections around them. Work under it in Ontario requires a TSSA Certificate of Authorization. IMW holds QA-01697 for B31.1 installation, shop and field.
Yes. Repairs and alterations to registered boilers and pressure vessels are carried out under TSSA certificate QA-01699, a field authorization. Repairing a registered vessel without the appropriate Certificate of Authorization can invalidate its registration.
B31.1 covers power piping — boiler external piping, high-pressure steam and hot water, power and district energy. B31.3 covers process piping — the fluids a plant processes or distributes internally. Allowable stresses, design margins, examination requirements and documentation all differ. Many plants contain both, which is why IMW holds both authorizations. See process piping.
Yes. Scheduled evening, weekend and holiday work is routine, and where a connection can be made without taking the system down, hot tapping often removes the outage entirely.
