Batch Digester Blowline Replacement, Neucel Specialty Cellulose

Allnorth provided 3D scanning and piping design services for this project. The blowlines from the batch digesters had to be replaced because they were failing due to stress corrosion cracking. No design or as-built drawings for the blowlines existed, and access to the lines for field measuring was limited. The client engaged Allnorth to scan the blowlines with our 3D scanner and create drawings for the sections that needed to be replaced. Allnorth scanned the piping, structural steel and equipment in the blowline area and used the 3D scan data to model the existing blowline, including defining locations and angles of branch connections, confirming the radii and roll of the long radius bends, and identifying the routing through congested areas. When the design drawings were completed, Allnorth worked with the client and the piping spool fabricator to coordinate the shop and field work so the installation was completed in the most cost-effective way.

Allnorth’s responsibilities for this project included:

  • 3D scanning and modeling
  • Piping design
