This LNG tanker truck is a special pressure vessel vehicle specially used for road transportation of-162℃ liquefied natural gas. It is suitable for distributing LNG from receiving stations and liquefaction plants to city gate stations, refueling stations and industrial users. It can also be used as a mobile filling unit. Used, 1m³ LNG can vaporize about 600m³ natural gas, which is extremely efficient. The mainstream configuration includes two sizes: 45m³ and 52.6 m ³, with a large effective volume and a rated filling mass of up to 25 tons. The tank body adopts S30408 stainless steel inner liner and Q345R low alloy high-strength steel outer cylinder. It is matched with a high vacuum multi-layer insulation structure. The static daily evaporation rate is as low as ≤0.10%/d, effectively reducing transportation losses. The design pressure of the equipment is 0.65-0.8MPa, the working pressure is 0.4-0.6MPa, and the filling rate meets the national standard requirements of ≤90%. It is safe and reliable. The tank has excellent insulation performance and lasting insulation effect. It can meet the needs of long-distance and short-distance transportation. It is an efficient, economical and safe LNG road transportation solution.
