This 24,600 L T50 tank is intended for lpg gas transport projects that require a 20FT ISO frame, LR classification and the specified ASME VIII Division 2 pressure-vessel configuration. The 20FT format is often preferred where terminal handling, route compatibility or project specifications favor a smaller frame. A 40FT T50 model may provide greater nominal volume, but dimensions, tare mass, classification and logistics also change. Model selection should therefore consider the complete transport requirement rather than capacity alone.
