DTΦ273/Φ19-3.95/3.95-37-4.5: Heat exchange tubes with a diameter of Φ19; the design pressure on the tube side is 3.95 MPa and the design pressure on the shell side is also 3.95 MPa. The heat exchange area is 37 square meters, and the length of the heat exchange tubes is 4.5 meters. What’s uncertain is that Φ273 might be the inner diameter of the shell.
