The valve is designed to move in the only opposite direction during operation, specifically during start-up so that the valve contracts downwards with
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
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
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
The pipe connecting the plate-fin heat exchanger to the liquid-air subcooled gas is the largest diameter pipe in a set of large air separation units.
Positioning of pipe racks, height of gas-liquid seals, requirements for pipeline compensation, lead-in and insulation of instrumentation pipes, ways o
A small air separation plant has more than 150 pipelines inside the cold box. Most of the piping has been verified, calculated and combined with the d
The design of the piping in the cold box of the large air separation units is complex and complicated, and each pipeline has its own process requireme
Based on the technical characteristics of the different drive solutions, the analysis and study of various aspects, such as investment, energy consump
