Leak repair role

When a transformer on an aluminum smelter plant at a power station had an oil leak, authorised Belzona contractor, C & D Environmental Co was tasked with finding a reliable leak repair solution.

The base of the transformer was heavily corroded in one corner.

Belzona's engineers decided to fabricate a tray that could be bonded to the corroded area, creating total encapsulation of the fins and preventing future corrosion.

Internal surfaces and edges of the tray were prepared using an MBX Bristle Blaster. The pin hole leak was plugged using Belzona 1291(ESMetal) a rapid curing, emergency live leak sealing putty stick. The bottom vertical edges and transformer base were cleaned and degreased using Belzona 9111 (Cleaner/Degreaser).

Tray and transformer edges were then wetted out using Belzona 1831 (Super UW Metal). Finally a corrosion resistant coating, Belzona 5831 (ST Barrier) was applied to the underside of the tray, the edges and transformer lip to protect the repair.
