Belzona Repairs

Pump Supply & Repair Group were asked to offer advice regarding how to repair excessive corrosion to steel pipework on an exhaust steam manifold from a boiler house without replacing a complex manifold. In December 2008 the inlet flange and 1500mm of the pipe bore was coated internally in situ on site using Belzona 1511 Super High Temperature Metal to recover the surface profile, then coated with Belzona 1391 Ceramic HT Metal.

Inspection twelve months later revealed that although the coating had been attacked by cavitation caused by high pressure steam, no further damage had occurred to the pipework.

Once again, the Belzona coating has arrested the corrosion of the pipework, effectively increasing its life – additional coatings can now be applied to prolong the life further and avoid the expensive steel pipework replacement program previously carried out on this site. The repair was carried out during a three day shut down.
