Waterjet Pipe Cutting Machine (also can do plasma pipe cutting)

There are several types of waterjet pipe cutting machines. Follow this link obtain more information of portable waterjet machines.

We can roughly divide the waterjet pipe cutting machines into the following categories, rotation of pipe with a chuck on a regular CNC waterjet table, stand alone chuck for large pipes and cutting from outside of pipe, chuck or roller to rotate the pipe and cutting from inside of pipe, portable pipe cutting when pipe is already install in field.

waterjet cut pipe

A chuck is used to rotate a pipe on the traditional CNC waterjet cutting table. This type of waterjet cutting is usually for small diameter pipes.

International Waterjet Machines

With the CNC control, the combination of chuck rotation
and the linear axis on the CNC table enables the cutting of
various geometry on the wall of pipe.

A chuck is used to rotate a pipe on the side of a traditional CNC waterjet cutting gantry table. This type of pipe cutting enables cutting of larger size of pipes. Pipe is often placed on rollers.

With the help of CNC programming, waterjet can cut
and prepare pipes for various types of intersecting branches.

For large sized pipes, rollers are used to roate the pipe and
speical cantilever is constructed for waterjet cutting.

Waterjet with cantilever arm cuts large pipe from inside to avoid damage to the inner wall.

International Waterjet Machines

Portable waterjet are often used to cut pipes that are already connected in the fields. This portable CNC waterjet can cut off pipes and open holes in the pipe wall for branch connections.

International Waterjet Machines

In some cases, pipes must be cut from inside. This portable
waterjet cuts pipe from inside.

The wall thickness of pipe that can be cut depends on the type of material. Cutting speed also depends on the type of the material. Some materials may require adding abrasive to assist the cutting. In some cases, pipe diameter is small and the wall is thin, to avoid the water jet shooting through the opposite side, a sacrifical material shall be inserted in to the pipe. This waterjet pipe cutter is specially useful for cutting composite material pipes such as steel with contrete, steel with insulation material, or just GRP (glass reinforced plastic) pipes.

The water jet pipe cutting machine system consists of a high pressure water pump, a cutting table with water jet cutting head and abrasive feeding system.

The waterjet pump is 30-50 hp and when cutting with abrasive, the max thickness of mild steel is 80mm. The pump requires 3 phase electricity power supply of 220V -- 480V, 50 or 60 Hz, (specified by the customer). The pressurized water is fed to the cutting head through a high pressure whip tubing.

The cutting table includes a chuck that can rotate the pipe when the pipe is being cut. The rotation speed is adjustable to suit various cutting speed needs due to different wall thickness and type of the materials. Position of the waterjet cutting head is also adjustable to fit different diameters of the pipes. The cutting head can slide along the length of the pipe to choose desired cutting position. There is an abrasive hopper mounted on the same rail of the cutting head for feeding abrasive to the water jet. Customer should specify the weight of the pipe when ordering the waterjet pipe cutting machine.

Linear and rotational motions are both CNC controlled.

CNC controlled waterjet pipe cutting machine can also engrave on the wall of the pipes of just about any kind materials, PVC or metal, etc. In many cases, this is an optional add-on to the standard cnc water jet cutter. When cutting off the pipe, if manually tilt the cutting head, the water jet shoots at an angle to the pipe wall and make a beveled cut ready for wielding. In addition, if adding a 4th axis CNC control, the water jet can cut beveled hole in the pipe wall.

More videos to show waterjet pipe cutter makes special shape cut at the end of pipes to repare for welding from one diameter pipe to the same or different diameter pipe, and to cut opening holes of various shapes on the wall of the pipe.
