What is cryogenic temperature range in gas shipping?
Direct Answer
Option C: Extremely low temperatures below -50°C (e.g. LNG at -162°C)
Cryogenic temperatures in gas shipping refer to substances maintained below -50°C. LNG, for instance, is transported at approximately -162°C at atmospheric pressure. This extreme cold requires specialized materials like stainless steel or nickel-steel alloys to prevent brittle fracture of the ship's structure and ensure the integrity of the cargo containment system.
