Scale Problems
- Scale problems in the pipelines and the induction hardening machine.
- There are 9 secondary small pipes, they had to be cleaned manually every 2-3 months
Installation of a Vulcan S25 unit:
May 21st, 2018.
Note: scale was not manually removed before the Vulcan was fitted on source pipe (see photo).
Examination of secondary piping:
November 21st, 2018
- Since Vulcan S25 was installed, the Hyundai Engineering Team has stopped the regular manual cleaning process.
Observation: the flow rate with the Vulcan unit is now even higher than immediately after previous manual cleaning had been done. - After Vulcan S25 had been installed for 6 months, the secondary pipes were opened: scale that had been left in piping had disappeared and all 9 secondary pipes had become clean (see photo).
Observation: Biofilms in the cooling tower had disappeared since the Vulcan unit was installed.
Vulcan S25 was installed around 50 meter before the induction hardening machine.
There are 9 secondary small pipes with water meters. These meters were installed to make sure a stable flow rate. If the flow rate goes down, it would cause a problem of the induction hardening machine. Therefore, the pipes had to be cleaned manually every 2-3 months.
