How Freezing Tube Works

The working principle of the Freezing Tube is a glass instrument that uses the principle of heat exchange to cool condensable gas and condense it into liquid. It uses the principle of heat exchange to cool condensable gas and condense it into liquid. The cooling pipe is composed of bent metal pipes, which are installed in the liquid and are an important part of the power equipment. The exhaust gas generated by the power system can reduce the temperature through the cooling pipe. It can be divided into metal and plastic, suitable for machine tools, hydraulic machinery, and CNC machine tools as oil and water cooling systems. The cooling pipe is characterized by the manual assembly, the length of use can be adjusted arbitrarily, the diameter of the nozzle can be exchanged between round and flat, and the direction can be rotated at will.

In order to adapt to the cooling water quality of different pollution degrees, different materials are used, and corresponding different structural dimensions and installation methods must be adopted due to the cost of the cooling pipe. Although corrosion occurs occasionally, it has been largely controlled and resolved. However, it is still necessary to know the general corrosion mode and preventive measures in order to maximize the working life. The impact corrosion and abrasion of cooling pipes usually only occur on copper alloy pipes, which is a kind of localized corrosion. This is because the flow turbulence on the metal surface of the corrosion site is high enough to cause mechanical or electrochemical damage to the oxide protective film. It has pitting-like characteristics.

When air bubbles such as abrasive solid particles, gravel, mud, and other air bubbles are mixed into the cooling water, the occurrence of corrosion is often accelerated, but this corrosion can also occur in filtered cooling water without air bubbles. The turbulence intensity increases with the increase of the water velocity, but the geometry of the water flow is the decisive factor for the destruction of the protective film. For example, the turbulent flow intensity at the entrance of the pipe end is much higher than that in the pipe, so the impact corrosion occurs more at the entrance end of the pipe. When there is a blockage in the tube, impingement corrosion will occur near the turbulent flow area downstream of the blockage. In operation, although there is no copper alloy that is immune to impact corrosion, copper-nickel alloys containing trace element additives are more resistant to impact corrosion than other copper alloys.
