Question: According to the \"Code for Welding Technology in Thermal Power Plants\" (DL/T 869-2012), for a main steam pipeline with a design pressure of 3.98 MPa and a design temperature of 455°C, as well as an operating pressure of 3.83 MPa and an operating temperature of 435°C, what is the appropriate inspection rate? Should it be 50%, as specified in column 6 of Table 5 for \"steam and water pipelines and fittings with an operating temperature of 300°C < T < 450°C\", or 5%, as specified in column 10 of Table 5 for \"pipes for steam, water, oil, and gas with an operating pressure of 1.6 MPa < P < 4 MPa\"? What does a soda pipeline refer to? What is the difference in meaning from gas and water pipes?
Power plants deal with several types of media such as water, steam, fuel gas, and oil. By \"steam,\" it refers to steam pipelines; by \"water,\" it refers to water pipelines.
They all belong to thermal pipelines. . . . .
