GA-1216-DN25-P medium code-number-pipe nominal diameter-insulation code EL elevation
P means heat insulation, C means cold preservation
Keep it cold, GA may be ammonia
I have experience in the construction of related pipelines. Why are some insulated thermally and some insulated coldly? ? =============== The name of the medium is still based on the picture on the homepage of the Design Institute.
Of course, please refer to the design institute’s diagram. GA AG I have seen different design institutes use it to mean cold ammonia gas is used for cold ammonia gas, and thermal insulation or isolation is used for hot ammonia gas. What can be seen on the process pipelines related to the ammonia refrigeration compressor
