Equipment
Chapter 3, Introduction to the Equipment
Read this chapter carefully to become familiar with the
components and features of your window cutter.
USAGEAND APPLICATIONS
The window cutter is designed to cut access windows in
pipes ranging from 6” to 48” diameter, up to 1-1/4” thick.
An adjustable-depth milling mechanism allows you to precisely cut through the thickness of the pipe without damaging any internal structures.
The window cutter is mounted directly on a horizontal pipe.
For a vertical pipe, a guide ring the size of the pipe is
installed on the pipe at the top of the machine. Rings are
available for 16”, 18”, and 20” pipes; other sizes can be
made to order.
The machine can cut windows up to 36” in length axially
and from 10° to a full 360° radially.
