CASES

cases

Liquefied petroleum gas (LPG) storage tanks include compressed gas or liquefied gas tanks. According to whether the volume of the container changes, LPG storage tanks can be divided into two categories: fixed volume storage tanks and variable volume storage tanks. Large fixed volume LPG storage tanks are made spherical, while small ones are made cylindrical. Variable volume storage tanks, also known as low-pressure gas storage tanks or commonly referred to as gas holders, have a geometric volume that can change. They are tightly sealed to prevent air leakage and have the functions of balancing air pressure and regulating gas supply, with a general pressure not exceeding 60 MPa.

cases

LNG storage tanks are specialized pressure vessels used for storing liquefied natural gas (LNG), characterized by extremely high requirements for low temperature, high pressure, and safety reliability. They store LNG at an ultra-low temperature of -162°C to reduce its volume (the volume of LNG is approximately 1/600 of that of gaseous natural gas), facilitating transportation and large-scale storage.
