Design standards for dimethyl ether spheres

Seek the design standards for dimethyl ether spherical tanks: handshake
There are currently no standardized design criteria; currently, the design of dimethyl ether spheres is generally carried out with reference to the liquefied gas design standards.
Dear user UID77720, if you design a dimethyl ether sphere tank in accordance with the liquefied gas design standards, what should be the design pressure? :handshake :handshake
The standard value is 1.77 MPa; however, given the properties of dimethyl ether, a pressure of 1.2 MPa can also be used. Yet engineering firms generally do not allow the design pressure to be reduced to such a low level, as there are no relevant standards to guide this practice. Therefore, modern designs generally use pressures such as 1.77, 1.6, and 1.4. It is relatively easier to design spherical tanks with a volume of 3000 cubic meters or less; however, designing spherical tanks larger than 3000 cubic meters and selecting appropriate materials presents difficulties, which necessitates reducing the design pressure.
