Liquefied petroleum gas storage tank
Liquefied petroleum gas storage tanks have compressed gas or liquefied gas storage tanks, liquefied petroleum gas storage tanks according to container volume changes or not can be divided into two types of fixed volume storage tanks and mobile storage tanks, large fixed-volume liquefied petroleum gas tank Made of spherical, small is made of cylindrical. Active volume tank, also known as low-pressure gas tank, commonly known as gas tank, the geometric volume can be changed, tightly closed, not leak, and the balance of air pressure and adjust the amount of gas supply, the pressure is generally not more than 60MPa.
Spherical LPG storage tank is the main body of the spherical shell, which is stored materials and materials to withstand the working pressure and liquid column static pressure components, by a number of pre-pressed into a certain size of the ball assembly assembled. Spherical tank bearing is a spherical tank to support the weight of the body and the weight of materials stored components, can be divided into two kinds of column bearings and ball bearings. The most common is the equatorial tangent column bearing. The structure of a spherical tank is not complicated, but the spherical tank is more difficult to manufacture and install than other types of tanks. Moreover, most of the tank is a pressure or cryogenic container, which is mostly contained in the material is flammable, explosive, and large load, in the event of an accident, the consequences could be disastrous. Therefore, the design and use of the tank must be safe and reliable. The proper design of the tank structure must take into account various factors such as the nature of the loading material, design temperature and pressure, material, manufacturing technology and equipment, installation methods, welding and inspection requirements, ease of operation and reliability, impact of the natural environment, etc. . To meet the requirements of the process, with sufficient strength and stability, and the structure as simple as possible to make it pressing molding, installation group, welding and inspection, operation, monitoring and maintenance easy to measure.
