The DP Series is intended for demanding industrial environments, including applications listed on the original page such as petrochemical and wind power work. Actual suitability for a hazardous area must be confirmed against the applicable explosion-protection certification, site classification, and operating requirements.
The DP Series combines water and abrasive at the nozzle tip rather than mixing them upstream in the same way as conventional abrasive delivery arrangements.The rotary system and related fixtures can also be configured according to the workpiece size, weight, and specific processing requirements. According to the product design described by HEAD, this arrangement helps reduce abrasive-related pipeline wear while supporting cutting efficiency and stability.
The compact body, wheels, and rollers make the equipment easier to move between suitable work locations.This is particularly useful when large pipes, tanks, or installed structures are difficult to transport to a stationary cutting machine.The correct fixture depends on the workpiece dimensions, surface properties, cutting path, and site conditions.
Different fixtures address different workpiece geometries:
Waterjet cutting removes material without relying on a concentrated thermal cutting source. Compared with laser, plasma, and oxy-fuel cutting, this can help avoid conventional heat-affected zones and heat-related edge damage. Actual edge quality still depends on material characteristics and cutting parameters. Designed for Demanding Industrial Environments The machine incorporates explosion-proof electrical components and a safety-oriented structural design.
The HEAD DP Series Portable Waterjet Cutting Machine is designed for on-site cutting of large tanks and cylindrical vessels that are difficult to move to a stationary cutting machine. Equipped with a magnetic track carriage, it follows a guided cutting path along suitable magnetic tank surfaces, supporting controlled circumferential and profile cutting.
The magnetic carriage attaches to magnetically responsive pipe surfaces. Motor-driven magnetic rollers move the cutting head along the pipe wall.
An optional magnetic track provides additional guidance for circumferential cutting.
Pipe diameter: 120–1,850 mm
Wall thickness: 5–80 mm
Bevel cutting: up to 45°, as specified for this fixture
The magnetic track adheres firmly to magnetically responsive tank or pipe surfaces, providing both fixation and guidance for the carriage. When driven by an electric or pneumatic motor, the carriage travels smoothly along the magnetic track and the outer wall of the pipe or tank, allowing the waterjet cutting head to perform uniform cutting along the side surface.
The system also supports bevel cutting up to 45°. It is suitable for tanks and pipelines with diameters ranging from 800 mm to 10,000 mm and wall thicknesses from 5 mm to 80 mm.
The portable frame is equipped with four magnetic bases that securely attach to the workpiece. A variable-speed motor drives the rotating shaft along a rack-type scale for precise circular motion, while the cutting head can be easily adjusted along the rack to change the circle diameter.
It is suitable for cutting circles with diameters ranging from 200 mm to 600 mm and material thicknesses from 1 mm to 30 mm.
After adjusting the chain to the desired length, both ends are connected and fixed onto the side wall of the pipe. The carriage, equipped with a drive sprocket, is then mounted onto the pipe using the chain and sprocket system. By adjusting the chain tension, the carriage is securely fixed to the pipe wall.
When driven by an electric or pneumatic motor, the chain carriage moves smoothly along the chain and the outer surface of the pipe, enabling the waterjet cutting head to perform uniform cutting along the side wall. The system also supports bevel cutting up to 45°.
It is suitable for pipelines with diameters ranging from 150 mm to 1850 mm and wall thicknesses from 5 mm to 80 mm.

The DP Series is designed for portable cutting applications involving suitable pipes, tanks, and other workpieces. Its fixture options support circumferential cutting, circular cutting, guided profile cutting, and handheld cutting for specified applications.
The supported diameter depends on the selected fixture: - Magnetic carriage: 120–1,850 mm - Magnetic track carriage: 800–10,000 mm - Chain carriage: 150–1,850 mm These ranges are specific to the respective fixtures and should not be interpreted as a single range applicable to every configuration.
The magnetic carriage, magnetic track carriage, and chain carriage list wall-thickness ranges of 5–80 mm. The magnetic circle cutter lists a material-thickness range of 1–30 mm. Actual cutting suitability depends on the material, cutting geometry, and operating parameters.
Yes. The specified magnetic carriage, magnetic track carriage, and chain carriage configurations support bevel cutting up to 45°. Confirm the required bevel geometry and expected edge quality for the specific application.
Magnetic carriage and magnetic track systems rely on attachment to magnetically responsive surfaces. For non-magnetic materials or unsuitable surface conditions, the fixture arrangement must be evaluated separately. A chain carriage may be an alternative for compatible pipe geometries.
This equipment utilizes explosion-proof electrical components and is designed with safety in mind for harsh industrial environments. If use in specific hazardous areas, please confirm the relevant certification requirements, hazard classifications, local regulations, and installation specifications with HEAD and the on-site safety personnel.
Provide the material, pipe diameter, wall thickness, workpiece shape, required cutting path, and site conditions. Also indicate whether the workpiece surface is magnetically responsive and whether the installation area has specific hazardous-area requirements. These details help determine the suitable fixture and whether the proposed configuration needs further technical validation. 1,623 This equipment utilizes explosion-proof electrical components and is designed with safety in mind for harsh industrial environments.
