The Belzona Flange Face Forming kit is a unique repair kit developed to aid the flange face forming technology in combating the common problems with mating surfaces of flanged joints such as heat distortion, corrosion and erosion. In conjunction with Belzona 2-part epoxy repair composites such as Belzona 1111 (Super Metal) this flange repair kit provides a complete package solution which is simple to implement and cost-effective.
Corrosive action of chemicals, crevice corrosion, bimetallic corrosion and high pressure steam can result in the deterioration and subsequent leakage of flanges. Proven for over 10 years, the Belzona flange face forming technology eliminates the need for conventional cut and weld methods involving hot work and allows for the simple application in emergency situations, especially in areas with limited access such as on offshore platforms.
The Belzona Flange Face Forming Kit includes all the equipment required to effectively complete a Belzona flange face forming repair, eliminating the need for spare flanges of multiple sizes. It contains 6 reusable plastic formers to repair the most common flange sizes found in the industry, as well as all other necessary application tools for a quick and easy repair.
- Simple to use as all the necessary accessories are in one kit
- Each flange face former can be reused hundreds of times
- Lightweight allowing easy transportation to emergency situations and areas with limited access
- Minimised downtime as the kit eliminates the need for replacement parts
Applications for the Belzona Flange Face Forming Technology include:
- Restoring damaged flange faces
- Corrosion resistance for old and new flange faces
- Isolation of dissimilar metals from forming corrosion cells
- Can be used in conjunction with Belzona nozzle insert and the vessel lining solutions to form a continuous internal lining film terminated outside the process environment
