  • On- or off-site maintenance crews for heat exchanger re-tubing and maintenance

  • Pressure cleaning of equipment in a purpose designed wash down facility

Pipe Spooling

Specialised Welding Australia can provide fabrication, modification, and repair of various sizes of pipe spooling with a variety of ferrous and non-ferrous materials. SWA can fabricate pipe spools from standard pipe or from rolled and welded plates as required. Complete project spooling is available along with one off repairs or replacements. 

Experienced operators are available for internal weld overlay in sizes down to 40mm inside diameter providing a superior wear resistance barrier for abrasive environments as well as a chemical resistant barrier for corrosive environments.
