Better Cutting with Jetting

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, the 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 cleansing 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.

The 14th International Conference on Jetting Technology was be held in Brugge, Belgium, on 21-23 September 1998. Since 1972, when the first event was organised by BHR Group, the conference has been a major factor in the transfer of fundamental research and development into practical application.

Jetting Technology is an established international conference which has developed a reputation as the leading authority on the subject. As well as covering the latest research, technical developments and applications, the conference will address the issues that must be faced as jetting technology reaches maturity: health and safety, training and operational standards, operational and lifetime costs of jetting and its alternatives, the environmental advantages of recycling water and abrasive materials.
