It is consisted of a series of bare coils ( carbon steel, alloy
steel or durable heat steel) and header and other auxiliaries.
Tubes φ32, 38, 42 and so on, also as the request.
In the boiler, the role of superheater is to heat the saturated
steam to a certain temperature of superheated steam to increase
power plant efficiency. Repeater essentially further improves the
thermal power plant cycle efficiency.
With the artistic appearance and accurate size, the advanced
processing for bending tubes and welding, the first rate test
equipment and sophisticated technology.
The use of rehearters can further improve heat power of the power
station circulating and control the steam temperature of the end
blades of the steam turbine within allowed range. Zigzag
superheaters and reheaters of the Company are also unique with
rigorous production technique, first-class production flow line and
complete test methods.
All the raw materials will be firstly made pipeline cutting.
