SEN can prevent molten water from re-oxidation, it divides into internal installed type and external installed type according to the difference of the structure.
1.The flange adopts compound materials, better anti-corrosion property, and also easy for flow control.
2.The body adopts Al-C materials with perfect anti-thermal shock property.
3.Al-Zr-C compound materials has perfect anti-slag properties.
4.lt adopts anti-corrosion inner layer,decrease the expanding speed of the inner hole of the nozzles, increasing the service life.
5.Insulating fiber keep the temperature effectively and prevents molten water from condensation .
