Steam Heater Has A Certain Degree Of Corrosion Resistance
Sep 06, 2017

Steam heaters are heat exchangers that use high-temperature water vapor to heat low-temperature gases and are used for gas heating of exhaust expanders in large PTA projects to achieve process requirements. For large heaters, in order to save costs and the structure itself, each heater can be used in two series, using different materials, using two kinds of quality steam, to avoid energy waste, while saving manufacturing costs; for small heaters Can be made into one, simple structure.

Steam heater is made of steel and aluminum composite finned tube as a heat exchanger element, Steam (heat Exchanger) Electric Heater so it combines the steel pipe pressure and aluminum high thermal conductivity, excellent heat transfer performance, and has a certain degree of corrosion resistance, and it is compact, Easy to clean.

Steam heater specific features are:

(1) The heat transfer element uses the spiral fins, and the fins are integrally pressed once, Steam (heat Exchanger) Electric Heater so the connection with the base pipe is good, the contact resistance is small, and the heat transfer coefficient is high.

(2) It maintains a constant low resistance over a wide range of temperatures and has good resistance to temperature and vibration.

(3) finned tube is the wrong arrangement, so the heat transfer area, Steam (heat Exchanger) Electric Heater heat transfer coefficient is also high.

(4) pipe design distribution is very reasonable, and the air flow is very uniform.

(5) steam heater in the factory has been hydrostatic test to ensure that no leakage phenomenon.

Steam electric heater installation is also an important part, can not be ignored, the specific are:

(1) steam heater should be used before the inspection, Steam (heat Exchanger) Electric Heater mainly to see whether the collision or injury, if damaged, should be repaired, and the need for re-testing and testing.

(2) should be carried out according to the provisions of lifting and installation, lifting lifting to be smooth, to prevent the distortion of the components deformation, or hit the fins.

(3) After the steam heater is installed, clean up the debris, including all the places, Steam (heat Exchanger) Electric Heater to prevent clogging the fins, affecting normal operation.

(4) steam heater is not used, the internal water should be washed clean, so as not to freeze the pipe in winter, affecting the use.
