Belzona® 3211 Protects Lpg Spheres



Oil & Gas (OILG)



Tanks and Chemical Containment Areas (TCC)


Customer Location:

International Oil Company


Application Date:

October 1996


Application Situation:

Pressurized storage spheres for Liquefied Petroleum Gas (LPG).



Water penetration through original insulation system had allowed severe underlagging corrosion to occur. The site is an exposed marine site and deluge systems on the sphere are regularly tested so that watertightness is imperative.



Belzona® 3211 (Lagseal)



Foam glass insulation


Application Method:

The insulation was re-installed using a closed cell foam glass that is impervious to water and Belzona® 3211 applied in accordance with Belzona Know-How Leaflet TCC-4.


Belzona Facts:

Trials with two alternative systems were not successful. Use of Belzona® 3211 in conjunction with a closed cell foam insulation will provide maximum resistance to water penetration. To date three spheres have been protected on the site.
