Issues with 2000m3 LPG spheres – sphere analysis.

2017-04-10 View Original

Thread Content

For an LPG spherical tank with a capacity of 2000 m3, and where the local average monthly minimum temperature is -37 degrees Celsius, what material should be used? Does the outer surface need to be insulated? If it isn’t insulated, will the liquid inside turn into a solid?

It is recommended to check whether it falls under the “low temperature and low stress operating conditions”

16MnDR material can meet the requirements.

The material is 16MnDR; insulation is required on the outside. Without insulation, LNG will not turn solid at -37 degrees Celsius.
