Tank repairs
February 20th 2012

Belzona has refurbished a leaking caustic tank for a global soft drink manufacturer at its bottling plant in London. Engineers wanted a long term repair solution for a tank where caustic acid was leaking from welded seams. The tank was in a stainless steel secondary containment area and comprised four half-round sections welded together. It held 8000L of 28% caustic soda.

The tank was drained and the area pressure washed to ensure adhesion of Belzona products. An 80mm wide repair area was masked off along the length of the welded seam and prepared using a Monti MBX Bristle Blaster. The first layer of Belzona 1111 (Supermetal) was applied incorporating Belzona 9341 (Reinforcing Tape) to the repair area.

Once cured, a second coat of the reinforced product was applied. After removing the masking tape the product was left to cure and is expected to provide a long term, corrosion protection solution.
