High power graphite electrodes (HP)

HP GRAPHITE is an industry-leading manufacturer that integrates manufacture, marketing, export and supply of high power graphite electrodes in extensive applications. HP GRAPHITE has always been advocating the use of better materials and more advanced production processes to reduce energy consumption and material costs. 

The high power graphite electrodes produced by HP GRAPHITE have the following characteristics: 

  • High bulk density 
  • Low power consumption 
  • Relative high electric conductivity 
  • Free consultation for installation 
  • Whole-process after-sales follow-up 
  • Unconditional return in case of quality problem

Ordinary power graphite electrode surface quality

1、There are no more than two defects or holes on the surface of the electrode and the size shall not exceed the value in the following table. 

2、There is no transverse crack or longitudinal crack with width of 0.3-1.0 on the surface of the electrode. The length of longitudinal crack is not more than 5% of the perimeter of the electrode. The crack with width less than 0.3mm shall be ignored. 

3、The width of black skin area on the surface of the electrode is less than 1/10 of the perimeter of the electrode and its length is less than 1/3 of the length of the electrode.
