Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline cutting, in particular to a pipeline water cutting device. Background Art

[0002] Waterjet cutting, also known as water jet cutting, is a high-pressure water jet cutting technology. It is a machine that uses high-pressure water jet cutting. Waterjet cutting is gradually becoming the mainstream cutting method in industrial cutting technology.

[0003] Waterjet cutting has the following advantages: 1. Wide range of cutting. It can cut most materials, such as metal, marble, glass, etc. 2. Good cutting quality. Smooth cuts without rough, burred edges. 3. No heat processing. Because it uses water and abrasives for cutting, no heat (or very little heat) is generated during the processing. This effect is very ideal for materials affected by heat, such as titanium. And it can be used in special working environments, such as underground coal mines. 4. Good environmental protection. It uses water and sand for cutting. This sand will not produce toxic gas during the processing and can be discharged directly, which is more environmentally friendly. 5. No need to change the tool or the cutting machine device. One nozzle can process different types of materials and shapes, saving cost and time. 6. Flexible cutting. There is no restriction on the cutting direction, and various cutting shapes can be completed.
