Orbital cutting of tubes TUBE cutting is a necessary machining operation for the prefabrication, construction, maintenance, repair or removal of damaged parts caused by corrosion, for example. Tubular components are affected by channelled substances that affect the original condition of the tube. Oil, gas or water at high pressures are abrasive and can alter the corrosion of the tube chemically and/or mechanically. When the replacement of the tube is absolutely necessary, the cut is made in upstream and downstream sections of the damaged tube. This maintenance operation can be done on- site and requires the best equipment for a perfect surface quality before performing welding operations. Protem tube cutting and bevelling machines are portable. They are lightweight, reliable, easy to use and they ensure a perfect weld preparation with no heat affected zones on all types of materials, such as steel or inox tubes. The Protem product range includes several types of cutting and bevelling machines: TT-NG orbital cutting machines cut and bevel tubes with large wall thicknesses; the TT-LW series machines, with a simpler design, cut and bevel tubes up to 25.4mm (1"); The TTS-NG machines allow accurate cutting and/or bevelling of tubes and pipes, of all schedules, from 10.3mm (0.406") up to 273mm (10.7") OD in one simultaneous operation; and the TTS- RD machines have been specially developed to cut thin- walled tubes from steel and titanium in restrictive space conditions. They are composed of two rings: one fixed and one rotating. The tool holders are mounted onto these 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 perform simultaneous welding preparation operations in order to get a regular land, an appropriate counterboring if necessary, and a bevel as desired. The CTA – high-speed cutting and bevelling – machines tubes and pipes with OD diameters ranging from 60.3mm (2") to 914.4mm (36"). Tubes are cut and bevelled within just a few seconds. The TNO are high-speed cutting and bevelling machines that are designed to fit piping or tubing prefab applications, on-site or in workshops.
