Circulating water pipeline
Thread Content
Do the cooling circulating water pipes of equipment fall under industrial pipes in the category of pressure pipes? The pump head is 20~30 meters. . . .
Pressure pipelines refer to tubular devices that use a certain pressure to transport gases or liquids. They are defined as pipelines with a maximum operating pressure of 0.1 MPa (gauge pressure) or more, carrying gases, liquefied gases, steam, or liquids that are flammable, explosive, toxic, corrosive, and have a maximum operating temperature equal to or higher than their standard boiling point, and with a nominal diameter of 50 mm or more. Except for pipes with a nominal diameter of less than 150 mm and a maximum operating pressure of less than 1.6 MPa (gauge pressure), as well as the pipes that form part of the equipment used for transporting non-toxic, non-flammable, and non-corrosive gases. The poster can follow these rules and compare them with the diameter of the circulating water pipes in question to find out!
If the temperature of the circulating water is low, no amount of pressure will help
Of course, it’s not considered a pressure pipeline; the explanation on the 3rd floor is very clear.
Floor 3 is the correct answer; ignore the others: lol
The last sentence on the 3rd floor is incorrect. Pipes of liquids with a maximum operating temperature higher than or equal to their standard boiling point, and with a nominal diameter of 50 mm or more. This is the correct answer; what was said on the 4th floor is right
