Repair Stages
Application Situation
We used ASME PCC2 equations to estimate the number of wraps required to retrofit the pipe to design conditions. The defect was type A (thin wall), corrosion was external, and the pressure was relatively low (25 psi). 2 wraps of Belzona SWII were recommended to structurally reinforce the pipe and effectively stop corrosion on the pipe. This repair system can remain maintenance-free for up to 20 years.
Application Method
First, the pipe was grit blasted and prepared according to SSPC SP10. All the pitting and resurfacing was then done with Belzona 1121(Super XL-Metal) because of its longer overcoating time. The next day, they started applying Belzona SWII. They applied the wrap in 4 feet sections at a time, so every 4 feet they would consolidate the repair with Belzona 9382 and continue with the next section. Though the application was during colder climate, Belzona 1982 was chosen to give more working life and allow the crew to complete the application properly.
Belzona Facts
