Heat Treatment PWHT Superheaters and Reheaters Coils Annealing with High Quality

Product Description of superheater coil

1.A super-heater is a device used to convert saturated steam or wet steam into superheated steam or dry steam.

2.It is used in power stations.

3. Super-heaters are used in steam engines or in processes, such as steam reforming.

4.There are three types of super-heaters: radiant, convection, and separately fired. A super-heater can vary in size from a few tens of feet to several hundred feet (a few meters to some hundred meters).

1.Re-heaters are the same as the super-heaters but as their exit temperature is a little bit less than super-heaters and their pressure is 20%-25% less than the super-heater, they can stand less quality material alloys.
