Liquid nitrogen storage tank shell and shell pipeline weld impact

Tank pipeline and shell connection or shell weld quality is not up to standard.

Liquid nitrogen storage tank liquid loss increase reasons

Content

Tank pipeline and shell connection or shell weld quality is not up to standard. For example, in some areas in the south where the weather is humid and acid rain is serious, the shell is very easy to rust and perforate, so that the outside humid air enters into the sandwich, resulting in a reduction of the vacuum degree, the thermal conductivity increases, and the heat transferred per unit area increases, so that the daily evaporation rate of liquid nitrogen exceeds the standard.

More cryogenic LNG storage tank

LNG storage tanks and pipes are made of austenitic stainless steel. Austenitic stainless steels have excellent low temperature properties. But the linear expansion coefficient is high. under the temperature conditions of liquefied natural gas The shortening rate of stainless steel is about 3/1000, and for the 304L material pipeline, when the working temperature is -162 degrees, the 100 m pipeline can be shortened about 300 mm.
