Spherical tank gas holders are the rational shape for high-pressure storage because the pressurized gas tries to expand as a sphere, and the stress by inner pressure becomes equal.
Spherical tank storage of propane, butane, etc. as a liquid under high-pressure, and spherical gas holder storage of city gas as a gas under high-pressure.
Largest spherical tank for high pressure liquid gas
Our tanks boast shock-resistance features in its seismic design, which was analyzed using FEM (finite element method) and certified by a program of the High Pressure Gas Safety Institute of Japan (KHK). We have a long supply records (over 800 units) in Japan, China, Singapore, Saudi Arabia, and Peru since 1955.
