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.
