问题: Following asbestos removal several years ago, a section of a gas main pipe had been left exposed to water ingress from above and as a result had suffered corrosion and metal loss. The client required a solution that was quick, easy and safe to apply to a live gas pipe,that would replace the metal loss and provide lasting protection from further corrosive attack.

工况条件
Main gas feed pipe to boiler house at large University building.
施工方法
The application was carried out in accordance with a modified version of Belzona Know-How System Leaflet VPF-11. Belzona® 1161 was applied to rebuild and protect the badly corroded section of the pipe followed by a heavy coat of Belzona® 5831 for added corrosion protection.
贝尔佐纳使用效果
Belzona® 1161 and Belzona® 5831 were chosen for their surface tolerant properties. The alternative would have been to remove the corroded section of pipe which would have proved a very lengthy, labour intensive and costly procedure. The Belzona application took approximately 5 hours to complete spread over two days.
