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.

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.
Concrete, mortar and cement washings behave differently in drains. Removal has to clear the obstruction without causing unacceptable damage to the pipe.
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.
Chemical process deposits need reliable information about the material before water jetting or washing is chosen. Water cannot be assumed to be compatible with an unidentified process residue.
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.
Cleaning water can carry contamination into drains or the wider environment. The job needs a collection method and a drainage or waste route that is permitted for what the water contains.
Drill-pipe cleaning can use specialist water-jetting equipment. Pipe dimensions, previous contents, deposit condition, access and the inspection requirement all affect the method.
High-pressure water jetting is used to clean deposits from heat-exchanger tubes. Tube size and length, the process deposit, access and isolation all affect the equipment and method.
Water jetting is used for industrial tote and tank cleaning. For a tote, the previous contents, container construction and intended next use are central to the cleaning decision.
Large-bore pipe cleaning may use specialist water-jetting equipment. Pipe diameter and length, contents, condition, access and the amount of material to recover all affect the job.
Water jetting has specialist deburring and deflashing applications. Part material, the burr or flash and the dimensional or surface requirement determine process suitability.
Oil in cleaning runoff changes how the water should be contained and managed. Oil source, likely contamination, drainage layout and the available collection method are the main points to establish.
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 from coating removal can carry paint, corrosion products and other residues. The coating, containment method and permitted drainage or waste route need to be considered together.
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.
Water jetting is used for reactor and process-vessel cleaning. Previous contents, remaining deposits, vessel construction, isolation and the condition required afterwards all affect the method.
Silt mobilised during cleaning still has to be contained and recovered. Its source and possible contamination affect how the water and settled solids should be managed.
Water jetting is used for industrial tank cleaning. Previous contents, tank construction, access, isolation and the condition needed for the next use all affect the cleaning plan.
High-pressure water jetting is used to clean heat-exchanger tube bundles. The side being cleaned, tube dimensions, deposit, access and recovery requirement affect the equipment and method.
