Ronneby, Sweden: 6-8 September 2000

High pressure jetting technology offers a new approach to real life situations where other potential solutions cannot provide the same degree of accuracy, efficiency and performance. Although many of the operational advantages and capabilities are understood, there is still a need for additional information on the latest techniques, developments and applications.

The unique properties of jetting enable applications which must avoid the heating effects and forces associated with conventional tools. Recent technology advances have led to improved control systems and nozzle design and greater understanding of materials behaviour. At the same time, emergence of new materials such as composites and ceramics that can only be cut accurately with jetting has created even more opportunities for the use of the technology.

Novel applications of jetting technology have been made in areas such as land mine decommissioning, surgery, recycling of compact discs and cleaning of oil and gas installations. This diversity inevitably leads to opportunities for technology transfer between industries where similar technologies may have very different applications. The knowledge gap between these industries needs to be closed if the full potential of jetting is to be realised.

Now in its fourth decade, BHR Group's biennial Jetting Technology Conference continued to bring together the world's leading specialists in this technology. Since its first meeting in 1972, the Conference has led to the creation of a number of national meetings and associations to promote the applications of this technology.

With each Conference come new applications, new developments and improved equipment. The focus of the Conference has been steadily changing to reflect the range of new industries adopting jetting techniques to solve their production problems. Beyond industry, the technology is helping to solve some of the world's environmental problems in cleaning and recycling applications and in the decommissioning of explosives and other war materials.
