问题: Cutting and welding was deemed to be unacceptable due to the damage that would be caused to the lining inside the nozzle and the safety concerns. A flange face and surrounding bolts had become corroded from contact with Sulphuric Acid. The loss of metal in the flange was causing significant leaks around the flange. This led to environmental and safety concerns.

工况条件

The loss of metal in a flange was causing significant leaks around the flange. This led to environmental and safety concerns.

施工方法

The face was prepared using an MBX bristle blaster. A blank flange was used to form the face using a modified version of Belzona system leaflet VPF-13. Time was an issue so induction heaters were brought in to force cure the product. The cured product was machinined back once the former was removed.

贝尔佐纳使用效果

Cutting & welding the flange was not possible due to the safety implications it would have caused onsite. Replacement would have been more expensive, cause longer downtime and experience the same problems they had before.
