E.H WACHS Trav-L-Cutter Model E

Description

DESCRIPTION
When E.H. Wachs is mentioned, the product
that often comes to mind is our famous
Trav-L-Cutter. First introduced in 1949, Wachs
Trav-L-Cutter is a portable milling machine
designed to cut and bevel simultaneously on
most pipe materials and schedules. Secured
by its tensioning chain, the Trav-L-Cutter
drives itself around the pipe as it machines,
producing a weld ready surface.
Wachs Trav-L-Cutter will accommodate
sizes from 6"-72" O.D. (DN150–1800) with
the addition of additional chain sections.
Machining of larger pipe sizes, vessels and
other structures are possible - contact your
local Wachs representative for details.
VERSATILE DESIGN
Offered as a Model E Pneumatic or Model HE
Hydraulic, the Trav-L-Cutter is designed to
operate horizontally, vertically or anything
in between. Its special milling blades, with
standard weld bevel angles of 30 and 37.5
degrees, removing .188" (4.8mm) of material
during operation, leaving the pipe ends with a
fine milled finish.
The chain drive system maintains
continuous out-of-round compensation
while providing positive drive under all
conditions for accurate cuts. By using an
optional guide track and special guide track
wheels, accuracy of .005" (.127mm) can be
maintained even in zero visibility situations.
This cutting method facilitates section removal
in the field, where new sections pre-cut by the
same method can be quickly fitted in place.
OPERATES ANYWHERE
Wachs Trav-L-Cutter has been used in
a wide range of applications, including
natural gas, crude product and fuel
lines, radioactive environments, and for
demilitarizing ordinance including sectioning
missile fuel cells. It can also be adapted to
simultaneously cut off and groove pipe in one
operation. Cutters are available for Victaulic
and other grooved coupling systems.
The hydraulic Model HE is ideal for partial
or complete water immersion and subsea
applications available. Hydraulic models offer
the inherent advantages of a completely
sealed and self-lubricating closed loop
system. The Model HE is particularly suited
to field machining operations under the
type of difficult environments often found
on offshore drilling rigs, pipelines, and on
construction work in rivers and harbors.
