Commonly Used Methods of Underwater Cutting and Diamond Wire Saw Cutting

摘要

This paper introduces commonly used methods of underwater cutting, such as flame cutting, plasma arc cutting, high-pressure water jet cutting, explosion cutting, mechanical cutting, ect, and their working principles, characteristics, processing objects, working conditions, technical maturity as well as current status of developments. Using these methods for cutting undersea oil pipeline the subject of this composite material, is very difficult, even if the completion of cutting, efficiency is very low. We developed the use of underwater diamond saw which can be brought to effectively cutting oil pipeline, the technology for underwater cutting operations providing a new method of cutting. At the same time, the composition and working principle of this machine, and the working process of the main components is analyzed. Diamond cutting tools and cutting oil pipeline single-object structure, analysis of the rope saw the work of the main components of the process. By comparative experiments, it has been verified that the machine can effectively cut the oil pipeline, steel materials and reinforced concrete.
