Esco Tool released its APS-438 air-powered saw and WrapTrack system that cuts highly alloyed pipe perfectly square by providing a trolley that guides the saw around the circumference without wobbling. Good for repairing underground steam lines in situ, the saw cuts square with no HAZ and leaves a smooth finish for end prepping or joining pipes with couplings. Designed to fit pipe from 6 in. to 60 in. in diameter, the system is offered in 28 sizes of stainless steel bands that clamp onto the pipe and accept the saw which is mounted onto a trolley.
