The PREP 3 is a popular i/d locking, in-line feed end prep machines. The PREP 3’s power to weight ratio in electric drive form is unrivalled. A 4 jaw tool holder (chuck) allows use of up to 4 insert or form tools to enable bevelling of heavy wall pipe and tube. Simultaneous external, internal and facing of tubes can be performed with ease for accurate repetitive work. Its size, power, and functionality, makes it extremely popular in high volume boiler repair and maintenance work, tube facing, weld removal, and J-Prepping of the tube plates and panels.
FEATURE AND ADVANTAGES:
The PREP 3 is torque reactive. This means that the pipe or tube does not have to be fixed to be bevelled, making it particularly useful on-site, in maintenance and repair situations. This is due to the design and strength of the thru shaft system that locks to the bore of the pipe. The Jaw system itself consists of 3 equilaterally positioned machined jaw segments, retained and locked on an inner, ‘grooved’ expansion shaft. These grooves keep the jaws held securely in position, unlike other systems that use a metal or rubber bands for jaw retention. As the expansion nut is tightened, the jaws expand, locking tightly, and square to the bore of the pipe.
