The material to be removed is only part of the job. Pipe or surface condition, access, isolation, washwater recovery and the finish required can all change the method.
Deposit and process: what the material is, how it formed and any useful product or sample information.
Pipe or surface: dimensions, construction, condition and any coatings, linings or previous repairs.
Work area: access, isolation and whether the equipment can be taken out of service.
Recovery and finish: how solids and washwater will be collected, and how the finished work will be checked.
Reference sources for this library
These references cover the applications, safety points and environmental limits used across the library. Manufacturer material describes the named equipment or application, not whether it is suitable for every job. Regulatory and safety guidance is used only within its stated scope.
Water jetting can remove coatings from steel, but the required surface condition, the steel itself and the route for residues and washwater all need to be defined.
Water jetting has specialist applications in casting cleaning. The casting material, the residue to be removed and the required finish determine whether the process is suitable.
Water jetting can be used to prepare concrete surfaces. The existing concrete, the material to be removed and the specification for the next operation define the required finish.
Hydrodemolition uses high-pressure water to remove concrete. The engineering specification needs to define the area and depth of removal, what must remain and the required condition of the exposed surface.
Water jetting has specialist deburring and deflashing applications. Part material, the burr or flash and the dimensional or surface requirement determine process suitability.
Water jetting is used to remove paint-booth build-up. The coating, booth surfaces, nearby equipment and the way residues and washwater will be contained all affect the method.
Water jetting is used to remove pavement markings and runway rubber. Pavement type, the material being removed and the finish required afterwards determine whether it suits the area.
Water jetting can be used to strip coatings from pool surfaces. Pool construction, the existing coating and the finish needed for the next treatment define the cleaning objective.
