A new saw and track system that rapidly cuts through water wall boiler tube up to 101 mm O.D. to produce highly accurate, perfectly straight cuts with no HAZ (heat affect zone) has been introduced by Esco Tool of Holliston, MA, USA.
The MILLHOG Boiler Tube Panel Replacement System features the APS-438 Saw and EscoTrack System that easily attaches to a panel using weld tabs. Capable of cutting 101 mm O.D. tubes horizontally, perfectly straight with 1.57 mm accuracy and no HAZ, the saw can then be fit with a vertical track attachment for equally fast and accurate boiler tube membrane removal.
Equipped with a 3 hp pneumatic motor that runs on 6.2 bar shop air at only 2.27 cubic meters/min.(80 cfm), the APS-438 Saw uses proprietary reinforced fiberglass abrasive saw blades for quick cutting and long life. Fully supported by the steel track, the saw glides smoothly and the MILLHOG Boiler Tube Panel Replacement System eliminates the need for tube rework and grinding before beveling.
The MILLHOG Boiler Tube Panel Replacement System is available for rent or purchase. Pricing is available upon request.
