Basalt fiber provides thermal insulation for the innovative railroad tank car

The Fifth International Fair of Railway Equipment and Technologies EXPO 1520 saw an innovative railroad tank car designed for transporting molten sulfur, which was presented by ReylTransHolding MC LLC. The new tank car is part of a range of railroad tank cars for transporting chemically active substances.

Numerous innovative features of the model 15-9544 include composite materials used in the manufacture of heating jacket bottom.

According to ReylTransHolding, thanks to this innovation, new tank cars reduced the effect of such negative phenomenon as stable vortices that lead to heat loss through the bottom of the car. In conventional molten sulfur tanks, these vortices occur due to high thermal conductivity of steel (compared to composites), which is traditionally used in producing railroad cars.


In addition, the problem of boiler insulation has been solved in a different way, since superthin basalt fiber, tightly sewn into the mats with double-sided polyurethane coating, was used.

Along with the other constructional findings, application of superthin basalt fiber will help to save more than 80 thousand kilowatt hours of electricity being spent on the product temperature maintenance during transit.
