Application Situation
Crude oil transfer hose.
Application Method
The galvanising was grit-blasted off and a new sealing face formed using the Belzona® 1321. Rubber plugs were inserted to prevent excess material seeping in to the boltholes. Metal shims were inserted to ensure an adequate thickness of Belzona® 1321 was formed on the flange face.
Belzona Facts
Once the glavanised surface had been damaged, corrosion creep had ocurred beneath it. The use of Belzona® 1321 not only restores the profile of the sealing face but also offers long term corrosion protection. The entire application was completed for less than £1,000 ($1,600) compared to the £18,000 ($28,800) replacement cost of the hose.
