Belzona® Crude Oil Transfer Hose Repair

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

Offshore Oil Company

 
 

Application Date:

Summer 2003

 
 

Application Situation:

Crude oil transfer hose.

 
 

Problem:

The sealing face of the transfer hose flange had been damaged preventing a seal.

 
 

Products:

Belzona® 1321 (Ceramic S-Metal)

 

Substrate:

Steel with protective galvanising

 
 

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.
