The Challenge

Mechpro Solutions was awarded the project to be manufactured in our Beresfield NSW facility, therefor the team developed a comprehensive plan to not only manufacture, but also the logistics involved in delivering 14 Convection Banks to site in Mt Isa QLD under a nitrogen purge for preservation.

Our Solution

In 2024, Mount Isa Mines required the manufacture, testing and delivery of 14 new convection bank tube bundles for the furnace heat recovery boiler. The individual banks weighed over 12T each and were over 14m long and 6.5m wide. Each convection bundle required the fabrication and welding of four panels of tubes, inlet and outlet headers, non-destructive testing, hardfacing, hydrostatic testing, acid cleaning, nitrogen purging and transport to Mount Isa Mines.

Mechpro Solutions worked closely with the client to plan, build, test and deliver the convection bundles. Mechpro’s outstanding project management team ensured each bundle was delivered on time and of the highest quality. Mechpro devised a detailed schedule, provided monthly progress reports, inspection and test plans and manufacturers data reports. Client representatives were well informed throughout the process and invited to attend key milestone activities such as hydrostatic tests.

The Result

Incredible Project at Mechpro Solutions AU!
for 12 months it was nothing short of extraordinary. We were awarded one of our largest fabrication packages to date: the manufacture and delivery of 14 Boiler Convection Banks for a customer in QLD. Each unit, weighing approximately 12 Tonnes, pushed our team to new heights and showcased our commitment to excellence.

Just a few project numbers:
🔹 175 Tonnes of steel
🔹 10,192 beveled tubes
🔹 approx. 29 km of tubing and the manufacture of 14 headers
🔹 54,200 total welds, which included 5,300 Butt Welds
🔹 99.96% NDE compliance

More impressive, all this was done with zero safety incidents; all this would not have been possible without the dedication and expertise of our incredible team and the invaluable support of our trusted contractors
