Shell and Tube Condenser Maintenance Tips

Helpful Shell and Tube Condenser

Getting familiar with the knowledge about the shell and tube condenser or shell and tube evaporator may help you a lot, and by doing so, you can also take care of your devices in a better way and manage to expand its life span. On the market, you may find plain and finned, external and internal shell and shell and tube condenser as well as the shell and tube evaporator.

Features of Shell and Tube Condenser

The plain shell and tube condenser or shell and tube evaporator is used in the typical heat exchanger devices when the finned tubes offer an improved heat transfer surface. Another type will be the duplex tube. It is a tube inside a tube snugly fitted by drawing the outer tube on for the internal tube. It's valuable when the shell side fluid is not compatible with the materials satisfactory for the tube side fluid. The outdoors diameters of the shell and tube condenser or shell and tube evaporator range from 6 mm to 40 mm. The thickness normally varies based on the materials of construction and diameters. Tube lengths also range from 0.5, 2.5, 3, 4, 5 and 6 meters. They may be laid out either on an equilateral triangular pitch or a square pitch. The minimum pitch is 1.25 times of the outdoors diameter of tubes. When tubes are on square pitch a minimal cleansing lane of 6.5 mm is accessible. On account of their efficient heat transfers, the application of finned shell and tube condenser or shell and tube evaporator is broadly accepted. These are by far the most commonly transverse low fin type. The fin height is about 1.5 mm, with about 7 to 8 fins per cm tube length. It's typical to cut the tube diameter through the finning process so that the fin diameter can be confined within the limits of the initial stock tube diameter. In some applications like shell and tube evaporator, a roped tube surface with proper groove depth, pitch and helix angle look more suitable as a consequence of great drainage features.

How to Maintain Shell and Tube Condenser

As soon as your shell and tube condenser or shell and tube evaporator are found broken, usually people tend to fix them through expanding the ends of the tubes placed inside the tube sheet holes with a rotating and expanding tools. Craftsman usually drills the shell and tube condenser or shell and tube evaporator to the undersize and then ream to a diameter which is little bigger than the outside diameter of the tube. Sometimes, they would be soldered or brazed inside the tube sheet holes in the case that the tubes apply a small diameter. If you conduct a proper cleaning and maintenance of the shell and tube condenser or shell and tube evaporator, then their life span would be expanded and offer you a much less energy consumption.
