eNtsa - Innovation through engineering

13/09/2011

On Saturday, 3 September 2011, a team of engineers from eNtsa successfully implemented the 1st commercial application related to the patented WeldCoreTM technology, jointly developed by NMMU and Eskom. This was done at the Rotek facilities in Johannesburg on a component with a R1.2billion replacement value.

The application included the removal of a core sample and repair of the removal site by a Friction Taper Hydro Pillar Processing platform developed specifically for this application at eNtsa.

The cylindrical core sample removed from the turbine rotor disk allowed Eskom engineers to accurately determine sub surface creep damage. This Information provided adequate scientific evidence to create confidence in extending the service life of the current structure. This consequently now will lead to the postponement of capital expenditure and result in a major cost saving for Eskom.

This momentous event is the result of hard-work and research, co-developed by eNtsa and Eskom, over the past 8 years.

Congratulations to the team on this great achievement and much success to the roll-out of the commercialization branch of research.
