Large spherical tanks for storing liquefied gas, with a pressure of 2.5 MPa inside
It’s not necessarily the case; the tank pressure ratings vary depending on the manufacturing process used.
It’s not necessarily the case. Here, it’s around 1 Mpa
This depends on how large your requirements are and what size the design needs to be
It’s hard to say; they’re probably all over 10 kilograms.

This is also related to the structure of the spherical tank; there is a significant difference between those with insulation and those without it. For the liquefied gas tanks in typical petrochemical plants, the maximum pressure of propane is usually between 3 and 5 MPa. In contrast, the tanks used for petroleum liquefied gases with a main composition of C4-C5 compounds do not exceed 2 MPa, while for C5 hydrocarbons, the pressure may be no more than 1 MPa. For liquefied natural gas, spherical tanks without insulation layers are no longer suitable, as their pressure resistance and performance under temperature effects do not meet the required standards. Liquefied natural gas at room temperature must be stored in specialized tanks capable of withstanding pressures up to 15 MPa. As for large liquefied natural gas tanks equipped with insulation layers, they can be spherical in shape, such as the spherical tanks on liquefied natural gas carriers; their pressure resistance generally does not exceed 2 MPa, but they require a reliable refrigeration system for support as well as safety relief devices. For tanks containing some gases that are prone to liquefaction, such as liquid chlorine, liquid ammonia, Freon, phosgene, VCM, chloromethane, etc., the pressure in these tanks is not very high, but a high level of safety is required.
