A saw and track system for accurately cutting pressure vessels up to 60-inch diameter in preparation for hydrostatic testing and complete fabrication is being introduced by Esco Tool of Holliston, MA.
The Esco APS-438 Air Powered Saw and WrapTrack trolley lets operators rapidly cold cut vessels from 6-inch to 60-inch diameter with ±1/16-inch accuracy to permit better bevels for subsequent welding. Capable of cutting a 24-inch x 0.5-inch 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 three HP pneumatic motor, uses fiberglass reinforced abrasive blades capable of 4-3/4-inch cuts, and cuts all pipe schedules of P-91, Super Duplex stainless, and other hard materials.
The Esco APS-438 Air Powered Saw sells for $5,895 and the WrapTrack is priced from $395 up, depending upon circumference.
