Products and services

PROTEM tube cutting and beveling machines type TTNG are portable splitframes.

They are light weight, reliable, easy to use and they ensure a perfect weld preparation with no heat affected zones on virtually all types of materials, such as, steel or stainless tubes.

They are composed of two rings; one fixed and one rotating. The tool holders are mounted onto the rings. They can be opened into two “half-shells” which allows them to be mounted on any type of pipe at the required place for machining.

They perfom simultaneous welding preparation operations in order to get a regular land, an appropriate counterboring if necessary, and/or a bevel as desired. Different models enable to cover ranges of diameters from 1" to 168".
