FRP (Fibre-reinforced Plastic) Duct Replacement, Crofton Mill, Catalyst Paper

Allnorth provided 3D scanning and piping design services for this project. A section of 60” diameter ducting in this mill had failed and needed to be replaced. The problem section of ducting spanned two floors of the building and followed a complex route through multiple pipes and structural supports. The client wanted to maximize the pre-shutdown work on the ducting spools and ensure proper fit during their short shutdown. We scanned the ducting using our 3D laser scanner, then used the scanned 3D images to create a model of the section of ducting to be replaced. By using the 3D scanner for this project, Allnorth efficiently produced an accurate design that allowed for a successful installation during the client’s short shutdown.

Allnorth’s responsibilities for this project included:

  • 3D scanning
  • Mechanical engineering
  • Project management
