The wheels will be used to transport iron ore from mines in northern Sweden, where operating conditions include extremely low temperatures and heavy axle loads.
Designed for extreme Arctic conditions
Interpipe has developed a modified version of its own wheel design for the ULT 25 LL (Long Life) trunk line. The supplied wheels have a diameter of 920 mm, are designed for axial loads up to 25 tons and operate at temperatures reaching -40 °C.
The wheels are used on the Malmbanan railway line, which connects the Kiruna mining region in Sweden with the Norwegian port of Narvik.
The Malmban Line is one of Europe's key heavyweight railways, carrying trains weighing over 8,000 tons, and is considered a benchmark for mining logistics in the region.
The delivery highlights the role of specialized steel railway products in ensuring the transportation of iron ore under difficult operating conditions.
Extended service life and performance
The ULT 25 LL wheel design is designed to provide a longer service life by:
- increased rim thickness,
- optimized tread geometry,
- additional machining allowance for reprofiling.
These functions allow you to extend your usage cycles.
