Introduction:
A specialized cutback finishing tool designed for 3LPE/3LPP coated pipes. The system removes the PE/PP layer over a specific cutback length while precisely preserving the epoxy (FBE) layer, creating a clean and controlled pipe end preparation solution.
Solution:
Selmers developed an advanced knife peeling system that removes the top PE/PP coating through a controlled rotational process. The system ensures precise coating removal for optimal pipe joint preparation in pipeline construction and coating applications.

- Dual Knife System
- Coarse knife for primary coating removal
- Fine knife for precision edge finishing
- Independently adjustable knife mechanisms
- Cutback Length Configuration
- Adjustable range: 50 – 300 mm
- Precision length setting
- Digital length control interface
