Forming New Manway Sealing Face

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

Oil Major, North Sea

 
 

Application Date:

March 2006

 
 

Application Situation:

A vessel was undergoing a change of use and required to have the manway sealing face protected from the new operational fluids.

 
 

Problem:

Existing Carbon steel would be subject to corrosive attack if the manway was not isolated.

 
 

Products:

Belzona® 1111 (Super Metal)
 

Substrate:

Carbon Steel

 
 

Application Method:

Application completed using a modified VPF-13 Know How System

 
 

Belzona Facts:

Hot work was not permitted so a weld overlay was not feasible and the finished job required to be a sealing face so hand coating was not deemed suitable. Belzona provided a perfectly formed corrosion resisting sealing face.
