Know more about the components of your Heat Exchanger Tube
It always helps to know more about the components of your heat exchangers so you will know how you can better take care of them and extend their life span. Heat Exchanger Tubes are plain and finned, external or internal. The plain tube is used in the normal heat exchanger units while the finned tubes give an increased heat transfer surface. Another type is the duplex tube. It is a tube within a tube snugly fitted by drawing the outer tube onto the inner tube. It is useful in conditions where the shell side fluid is not compatible with the material satisfactory for the tube side fluid. The outside diameters of the tubes vary from 6 mm to 40 mm. The thickness generally varies depending on the materials of construction and diameters. Tube lengths also vary from 0.5, 2.5, 3, 4, 5, and 6 meters. They are laid out either on an equilateral triangular pitch or a square pitch. The minimum pitch is 1.25 times the outside diameter of tubes. When tubes are on the square pitch a minimum cleaning l...
