Light Weight Design for Liquefied Natural Gas Tank Assembly
Our LNG tank with double-layer air supply frame features 20kg/set weight reduction than similar gas storage equipment (taking 450L double-layer frame as an example).
An automobile manufacturer has completed a sampling test for weight of LNG cylinders from four different suppliers, including Sinoma. Results are shown as follows.
LNG vessel manufacturer | Sinoma | T | F | S |
Total weight ( KG ) | 782 | 807 | 805 | 803 |
3. Heat insulation performance of our LNG tank is far superior over manufacturing standard
Low temperature performance index | Parameters comparison ( 450L as an example) | |
Sinoma standard | Manufacturing standards | |
Static evaporation rate | 1.67%/d | 2.1 %/d |
Vacuum layer leakage rate | 2.3 ×10 -10 Pa ·m3/s | 6 . 0 ×10 -8 Pa ·m3/s |
Leakage and degassing rate | 5.9 ×10 -10 Pa ·m3/s | 6.0 ×10 -7 Pa ·m3/s |
Low temperature vacuum degree | 1.8 ×10 -3 Pa | 2 . 0 ×10 -2 Pa |
Burning test time | 90min | 40min |
Lossless storage time (test medium: liquid nitrogen) | More than 12 days | 5 days |
4. CNHTC did a comparison test for pressure and time of LNG tanks from three suppliers. Test results are shown below:
Company / pressure / time | 17th | 18th | 19 th | 20 th | 21 th | 22 th | 23 th | 24 th | 25 th | 26 th | 27 th |
Sinoma | 0.4 | 0.6 | 0.75 | 0.85 | 1.0 | 1.1 | 1.25 | 1.4 | 1.5 | 1.65 | 1.72 |
A | 0.4 | 0.65 | 0.95 | 1.15 | 1.4 | 1.7 | 1.8 | 1.75 | 1.8 | 1.8 | 1.8 |
B | 0.4 | 0.6 | 0.85 | 1.05 | 1.25 | 1.5 | 1.75 | 1.75 | 1.8 | 1.75 | 1.75 |
Results shows
a. The natural gas tank from A supplier started the first gas releasing on March 23rd.
b. The natural gas tank from B supplier conducted the first gas releasing on March 23rd, and automatically closed the valve after loss of pressure.
c. Sinoma's tank released gas at 1 am on March 27th, and automatically closed the valve after loss of pressure.
Conclusions
a. The heat insulation performance and evaporation rate of Sinoma's LNG tank are superior over that of other suppliers.
b. Lossless storage time of Sinoma's LNG tank is 4 days longer that those of A and B suppliers.
