Is there insulation material on the new hydrogen compressor pipeline? Thanks!
There isn’t any; the pipeline section connected to the press isn’t insulated at all. There is a cooler at each stage to reduce the temperature, and insulating it would hinder heat dissipation, which is not conducive to the proper operation of the press
The pipes at the first and second stages, leading up to the cooler, are at high temperatures and require insulation.
No, adding insulation affects heat dissipation.
The pipelines inside the machine do not require insulation; if the process demands a high outlet temperature, the water cooling at the outlet can be removed, and the outlet pipeline can be insulated.
Whether to include insulation is purely a matter of design philosophy; many people believe that the inlet should be insulated, otherwise liquids may form at low temperatures, at the dew point. Some believe it’s unnecessary; I personally lean toward the latter – where does liquid pure industrial hydrogen, consisting of four nines or five nines, come from? Insulation is required at the outlet of the compressor or at the outlet of each stage. The function of insulation is not only to keep heat in but also to prevent burns; insulation should be installed at the compressor outlet where the temperature is around 100 degrees.
