Waterjet Pipe Cutting Machine

WPCxxyyA5 series machine is a versatile waterjet pipe cutting system. It cuts pipes with high pressure water jet. This system can be used to cut pipes of various materials especially good for cutting composite material pipes that are not suitable by other types of cutting methods.

WPC -- is the product code for pipe cutting machine.
xx-- the table length (x100 mm). The actual pipe length can be longer than the table length.
yy -- the maximum diameter (x100 mm) of the pipe that can be cut.
A5 -- Max 400 MPa Waterjet pump

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 can rotate the pipe when cutting. 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.
