Portable machining, cutting and welding equipment

THE tube cutting machines of the Protem TT-NG series are accurate in cutting and/or bevelling tubes and pipes of all schedules individually or in one simultaneous operation. These machines are especially designed to machine heavy wall tubes and pipes. They are very robust and can be installed in various positions. Their split frame configuration allows their opening in two half-shells. For the manual clamping four independent adjustable jaws are used. The machines have a rear centering feature and completely enclosed drive gears for the operator’s safety. The TT-NG can be equipped with ovality copying slides enabling to correct the defects of ovality of tubes and pipes. They can also be remotely controlled for operations in areas under ionising radiations. The Protem

US150 portable pipe bevelling tool is one of the most powerful, robust, reliable and versatile bevelling and facing machines in the world, Protem claims. The US 150 covers ranges of diameters ranging from from 5.9" to 20" ID (150-508mm). The standard tool plate will accept multiple tool bits, allowing up to four simultaneous machining operations. Such operations may include bevelling, facing, counterboring, compound bevelling, OD chamfering, removal of weld joints on tube sheets, and lengthening of tubes on tube sheets. The US150 features a self-accepting torque system and an integral drive motor. The robust US150 will perform repeatable high quality weld preparations on all types of materials including stainless steel duplex, super duplex, inconel, P91, etc. The electric

BB machine can be used either on-site or in the workshop. This heavy-duty beveller will bevel, face and counterbore individually or simultaneously heavy wall pipes. It will perform repeatable high quality weld preps on most metal pipes including stainless, duplex, super duplex from 3" to 24" outside diameter (88.9mm to 610mm OD). The machine is a bench beveller, can be fixed on the floor, is easily installed and clamps the outside diameter of the pipe. It can be easily operated by one operator. Used with the optional profile tracking device, it will machine oval pipes, leaving a root face of a consistent width, which is required when using orbital welding heads.
