ESCO Tool has introduced a pneumatic saw, universal pipe trolley kit, and circumferential track mount system claimed to be ideal for cutting concrete-lined pipe square. The MILLHOG APS-438 air powered saw features a fiberglass reinforced blade for cutting concrete-lined steam pipe and leaves a perfectly square cut for subsequent welding or to assure a flush fit for couplings.

The saw mounts on a trolley that has four V-grooved steel wheels and glides along a rugged steel WrapTrack System which can be sized to fit pipe from 6 to 60 in. diameter (152 to 1,524 mm). Attaching to the pipe’s circumference, the WrapTrack incorporates steel bands that correspond to the outside diameter of the pipe and the saw mounts rigidly on the trolley, resulting in accurate cuts. This saw, according to the supplier, also is well suited for cutting stainless steels, Inconel, and other highly alloyed pipe without leaving a heat-affected zone.
