Industry:

Petrochemical (PETR)

 
 

Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

Fuel storage depot, Italy

 
 

Application Date:

June 2013

 
 

Application Situation:

Two transfer pipelines for oil and hydrocarbons at the fuel handling facility. With no scheduled shut-down the pipelines required repairing/protecting whilst in service.

 
 

Problem:

The pipelines were suffering from external corrosion, which had led to thin walls with minimum thickness in some places reaching 1.4mm, whereas the original wall thickness was 9.52mm.The client required a composite repair compliant to ISO/TS 2481 that could be completed on both pipes within a limited timeframe and without the need for shutdown.

 
 

Products:

Belzona® SuperWrap

 

Substrate:

Steel

 
 

Application Method:

The application was carried out by validated applicators in accordance with Belzona Superwrap procedures which follow System Leaflet VPF-11.

 
 

Belzona Facts:

Belzona’s fully compliant SuperWrap system was chosen and designed to Belzona’s most stringent standards. The hydrocarbon pipe required two layers of material, whereas the oil transfer pipe was encapsulated using five layers. Application took place in June 2013 and the client was so satisfied with the outcome, they ordered similar repairs to be carried out on the rest of the exposed pipework in the following months. The expected service life of this application is a minimum of 10 years, which could be extended during a 2023 inspection.
