Pipelines linked with liquid throttle valves, such as liquid air, liquid nitrogen, liquid argon, etc. Due to the structure of the valve fixed to the w
The design needs to strictly distinguish between different types of pipelines, which are not involved in synchronous shrinkage, such as not in the sam
The air brings the cooling source to the lower tower through heat exchange, while the temperature drop after expansion also depends on the mid and bot
Designers need to calculate and analyse and then judge that the whole process of realisation is that firstly the temperature of the gas source drops m
Synchronous shrinkage is the main consideration in the design of the pipeline is that the temperature difference between the tower temperature and the
The equipment arrangement of the pipeline should be easier to install and inspect and safer. The synchronised shrinkage piping design approach is of g
The simplicity of the piping arrangement reduces the installation work, reduces the installation workload and at the same time reduces the weld seams,
With the same process flow, it is possible to save approximately 10-20% of aluminium material by arranging the piping along the tower compared to the
In accordance with the characteristic that the coefficient of linear expansion of the same metal material at the same temperature is the same or close
The road to large-scale liquid air separation plants， the choices of horizontal main cooling or vertical main cooling need to be considered from the p
When the large diameter pipeline involved in non-compensation, the force of the weld application design means to make it as small as possible to avoid
With the development of large air separation units, the pressure piping and diameter in the cold box has reached more than 1300 mm, such a diameter ha
