Saw and Track System Allows Rapid Cutting


A saw and track system for accurately cutting pressure vessels up to 60-in. diameters in preparation for hydrostatic testing and complete fabrication is being introduced.


The Esco APS-438 Air Powered Saw and WrapTrack trolley lets operators rapidly cold cut vessels from 6-in. to 60 in. dia. with ±1/16 in. accuracy to permit better bevels for subsequent welding. Capable of cutting a 24 x 0.5 in. wall vessel in 40 minutes, the saw is ideal for cutting a vessel cap after hydro-static testing to allow beveling and welding the cap into another vessel.


Fully supported to glide smoothly and reduce operator strain, the Esco APS-438 Air Powered Saw mounts rigidly in the WrapTrack trolley using four “V” grooved stainless steel roll guides.  It has a 3 HP pneumatic motor, uses fiberglass reinforced abrasive blades capable of 4-3/4 in. cuts, and cuts all pipe schedules of P-91, Super Duplex stainless, and other hard materials.
