| Abstract | A review of general principles of the application of pre mixed abrasive water jet is also discussed, and that is widely used in different fields of the modern industry. Technical applications of ultra high pressure abrasive water jet are used with success for cutting steel ducts, even when these are reinforced with fibber systems or internal protection. The steel and reinforced elements can also be cut simultaneously with concrete structures. The use of tools specially developed to actuate in surface work locations and for cutting through walls ensure the success of this job. The new technology is an athermic system that does not generate heat, scrap, or gas, and this can be favorable for the stability of the base metal grains, as it is known that great energy can promote an adverse growth of these grains when temperature gets close to 1,038° C. The base metal grain growth is harmful as it weakens the metal that needs to be repaired. In this process, the elimination of the danger of an explosion results in better safety conditions, even though safety remains as a critical issue in the subsequent welding of the new segment. In this case, the effective use of the pre mixture abrasive water jet may provide better quality welding and greater safety for the new duct segment. This chapter discusses a review of general principles of the application of pre mixed abrasive water jet that is widely used in different fields of the modern industry. Ducts are one of the most trustful and secure means to transport fuels such as oil and gas. The reduction of wall thickness caused by corrosion is the major maintenance problems that can affect the duct structure. Inspections are performed with the use of an instrumented "pig" or an ultrasonic scanning device that can detect a variety of defects caused by corrosion. Technical applications of ultra high pressure abrasive water jet are used with success for cutting steel ducts, even when these are reinforced with fibber systems or internal protection. Several laboratory tests were performed with different abrasive suspension concentration using a 200 mm diameter duct, and approximately 10 mm wall thickness. The laboratory tests demonstrated that it is possible to cut steel ducts with abrasive pre-mixed water jet without problems. |
