Esco APS-438 trolley for duplex pressure vessels

29 September 2017

Esco Tool of Holliston, Massachusetts have introduced a saw and track system for accurately cutting pressure vessels up to 60″ dia. in preparation for hydrostatic testing and fabrication.

The Esco APS-438 air-powered Saw and WrapTrack® trolley lets operators rapidly cold cut vessels made from pipe schedules of P-91, super duplex stainless or other hard materials in 6″ to 60″ dia. with ±i/16″ accuracy to permit better bevels for subsequent welding. Capable of cutting a 24″ x 0.5″ wall vessel in 40 minutes, the saw is ideal for cutting a vessel cap after hydrostatic testing to allow beveling and welding the cap into another vessel.

The Esco APS-438 Air Powered Saw mounts rigidly in the WrapTrack® trolley uses four “V” grooved stainless steel roll guides. It has a 3 HP pneumatic motor, uses fiberglass reinforced abrasive blades capable of 4-3/4″ cuts.
