Environmentally safe surface preparation with ultra-high pressure water jet technique

Surface preparation is a challenging technical problem. The paper describes solutions where ultra-high pressure water jet technique is involved. In particular, the paint removal from traffic vehicles, such as wagons, airplanes and ships, and the derusting of pipelines, tanks, and vessels are discussed. The application of on-site abrasive water jet units for demolition of buildings and heavy equipment is discussed. Also, a newly developed ultra-high pressure system is introduced that combines high pump pressures with the possibility of using two water jet tools independently.
