Belzona® Rapid Elastomer Repair To Choke And Kill Hose



Oil & Gas (OILG)



Gaskets, Seals and Shims (GSS)


Customer Location:

Offshore Oil Company


Application Date:

February 2001


Application Situation:

Choke and Kill hoses inject cement based materials under pressure to close off wells when necessary. Several hoses had been returned onshore for inspection and revealed damage to the sealing face.



Damage had been caused to the rubber on the sealing face of the male hose connector, due to contact with sharp metal edges on the female connector. As a result of this a satisfactory seal was not being obtained and the customer was faced with returning them to the manufacturer for refurbishment.



Belzona® 2311 (SR Elastomer)



Rubber lining


Application Method:

The sealing face was manually prepared and the sealing face formed using an adaptation of Belzona Know-How System Leaflet GSS-1.


Belzona Facts:

As the customer was faced with returning the hoses to the manufacturer, the use of Belzona® 2311 resulted in a signifi cant cost saving, as well as ensuring that the units were returned to service as quickly as possible. The Belzona® 2311 repair was subjected to pressure testing prior to the hoses being returned to service and was successfully completed at 1300 bar.
