T-850 Collaring Station

Collaring by T-850 collaring machine is based on the patented T-DRILL-method. Both hot and cold forming procedures are possible. By cold forming it is possible to make collars in materials with cold forming properties, e.g. stainless steel pipes. Hot forming is used for mild steel pipes or aluminium alloy pipes. For hot forming the machine is quipped with heater arm and necessary control devices.

T-850 machine is semi-automatic: collaring, trimming and bevelling are made by an automatic work cycle, other functions are made manually by using push-buttons.

The machine is used in e.g. SF6 Gear Switch applications.
