Description
Mechanical Internal Cutter
The Mechanical Internal Cutter is using to cutcasing, oil tubing and drillpipe. It features a device that permits the operator to set the cutter to any depth. And reset it to another depth without coming out of the hole. After mechanically anchoring, it is pressuring to rotate for cutting the drill string. If it is equipping with the spear, cutting and recovering can be completing at the same time.
Hydraulic Internal Cutter
Hydraulic Internal Cutter can be lowering into desired depth from cutted pipes string. The increased pump pressure can push piston downward as to make blade stretch. And the blade rotates in company with drill tool to start cutting. It can be using for all kinds of casing, tubing and drill pipe in oil / geology department. If it is equipping with the spear, cutting and fishing can be completing at the same time.
Mechanical External Cutter
Often connected to the washover pipe, Model “RS-J” Mechanical External Cutter can cut off and recover the pipe quickly and effectively, and is suitable for externally cutting drill pipe, casing, tubing and the like.It is spring fed automatically so that it can avoid the cutter breakdown which may be resulted from the larger pulling force.
Hydraulic External Cutter
The Hydraulic External Cutter Type RS-S is an external pipe-cutting tool, which knives are hydraulically actuating by circulating drilling hydraulic load. It is usually connecting with the washover pipe and can cut the fish at its any section. Compared with the mechanically-actuated one, it has the advantages of simple operation and quick cutting.
