GE Turbine.

The GE Turbine was partially disassembled for inspection. 7th stage blades being replaced in HP turbine section. Stationary diaphragms of last two stages of LP turbine section were removed for inspection and it was determined that they had been rebuilt with Belzona 1311 two outages prior (16 years ago!).

Products:

Belzona 1311 (Ceramic R-Metal)

Steel

 
 

Application Method:

Only one power pack of Belzona 1311 was needed to repair four diaphragm halves and four casing bells. The application was carried out in accordance with Belzona Know-How System Leaflet CEP-1.

 
 

Belzona Facts:

Following inspection from a scheduled outage for the plant confirmed that the GE Turbine that previously applied Belzona 1311 on the equipment had held up for 13 years! The customer elected to rehab same repairs! The application was accomplished in one day, start to finish, and did not negatively impact the planned outage by causing any further delay. Belzona 1311 had held up remarkably well, but all parties made the decision to blast off the existing Belzona that remained on the diaphragms and re-apply Belzona 1311 to ensure many more years of service.
