CERN developed the orbital cutting machine for repair of awkwardly located pipes in tight spaces. It is relevant for the industrial piping needs of accelerator facilities, as well as in sectors with environmental hazards, such as oil and gas piping, heat exchangers, and piping in nuclear plants.
Advantages & Applications
- Solution more compact with respect to other solutions on the market
- Easily adaptable to a wide range of pipe diameters, thickness and material
High energy physics laboratories.
Oil and gas industry.
