Belzona repairs scored shaft on a valve
Industry: Power (POWR)
Application: MPT-Mechanical Power Transmission (MPT)
Substrate: Carbon steel
Customer Location: Scotland
Application Date: October 2024
Products: Belzona 1212
Problem: A small hydroelectric plant owned by the local water authority had a series of gate valves. One had a score on a shaft used to actuate the valve. This score was forming a leak path.
Application Situation
This leak was becoming a concern for the plant owner. A contractor was called in to disassemble the valve & carry out a repair. The turnaround time on new parts was prohibitive so a Belzona solution was sought.
Application Method
The score was first ground out using a pencil grinder. It was also heated to remove any oil within the substrate. Belzona 1212 was then applied & overbuilt by ~2mm. The product was then dressed down smooth with the shaft surface.
Belzona Facts
The repair itself took around 1/2 a day to complete.
