1，GENERAL INTRODUCTION OF TRAV-L-CUTTER

•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.

•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 SUNBOW representative for details.

•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.

2，USING ENVIRONMENT

•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.
