Water jet cleaning, or waterjet cleaning machine is widely used process for the removal of material, coating, or contamination from the surface of material. Watex has experience with all types of water jet cleaning machine and specializes water jet blasting technology .


Water jet cleaning process removes coatings with one of two different mechanisms: erosion or delamination. Erosion is used on the majority of hard coatings such as metal .A special nozzle is used to break up the water stream into high strong droplets, which impact the surface of the coating. This causes small pieces of the coating escape from the surface, leaving the substrate intact.

The other method of removal is delamination, such as paint, adhesives, ceramic and abradable thermal sprayed coatings. With these softer coatings a nozzle keeps the waterjet stream intact, allowing it to penetrate the coating and break the surface , spreading out to delaminate the coating at the bond interface. Much faster cleaning rates are achieved with this type of removal as compared to the hard coatings that require erosion removal. It is crucial that this removal is understood so that the correct water jet cleaning nozzle and process parameters are selected.

20000 psi- 40000 psi water jet cleaning machine

Ultra high pressure water jet blasting uses water that is pressurized between 14,500psi, 20,000psi to 40,000 psi to remove coatings and debris from substrates.

Most water jet cleaning solution consist of the following subsystems:

Water jet pump to pressurize the water
Flat nozzle and rotative cleaning head
High pressure cleaning gun
Process control devices
Protective suit

Water jet cleaning process

Water jet cleaning process offers many benefits over competing conventional method to remove coatings. Traditionally coatings removed by the use of chemicals or abrasive blasting or machining. Chemical removal is expensive, slow, and not environmentally. Abrasive blasting or machining is more cost effective and faster than chemical processing, but cannot be used for lots of cleaning , which usually results in removal of excessive material, hence limiting the life of these parts. Water jet blasting is fast, environmentally friendly, and can only remove the coating with minimal to no substrate removal, making it the best alternative for coating removal for critical applications such as removal of thermal sprayed coating from gas turbine components.
