In ships carrying very hot cargoes above 140 degrees Celsius - which might cause local steel buckling - such as molten sulphur and asphalt, it is noticed that while sulphur is carried in independent tanks, the asphalt can be carried in tanks integral with the ship's hull. This is because:

The asphalt unlike sulphur is a viscous product and therefore does not transmit its heat easily to the steel bulkheads, allowing the steel to stay cooler than the cargo?

Tank coatings required for carriage of molten sulphur are best in independent smooth sided tanks and not in hull tanks?

Asphalt is not a dangerous cargo and therefore can be carried anywhere?

Molten sulphur is an extremely dangerous product and therefore needs to be carried in independent tanks?
