What Constitutes the Nominal Diameter and Length of Heat Exchangers?
What does the nominal diameter of heat exchangers signify?
For coiled cylinder heat exchangers, the nominal diameter (DN) is determined by the inner diameter of the cylinder. In steel cylinder heat exchangers, the nominal diameter is based on the outer diameter of the steel tube.
How is the nominal length of the heat exchanger defined?
For straight heat exchange tubes, the length of the straight tube section becomes the nominal length (LN). In the case of U-shaped tubes, the nominal length (LN) corresponds to the length of the straight parts within the U-shaped configuration.
