What Does Abrasive Jetting Machinery (AJM) Mean?
Abrasive jetting machinery is used for abrading surfaces of coatings, removing soil, discoloration, accumulated and hardened deposits, etc.
In trenchless rehabilitation methods, sewer pipelines are upgraded using methods such as cured-in-place pipe, thermoforming, slipining etc. Before these procedures can be carried out, the pipeline needs to be cleaned of debris and any accumulation or deposits in the pipeline. Water jetting is an effective way to clean out and prepare the surface for repair.
Trenchlesspedia Explains Abrasive Jetting Machinery (AJM)
Abrasive jetting uses water or an abrasive at high pressure directed at the surface to be cleaned. Cleaning abrasives include silica sand, slag, organic nut shells, synthetic particles, microballoons, glass beads and fruit kernels. The powerful blasting effect of the abrasive hydro jetting machine is capable of removing even hardened deposits.
Abrasive jetting machines are available as complete units including all components required for the jetting process. These components include a control panel for generating or intensifying pressure, wheels, nozzles, cabinets, dust collectors, etc. Component parts are also available separately in the market to customize the machine to client specifications.
There are three types of abrasive jetting machines: abrasive water jet and water jet cutting machines, air abrasive jet cutters and precision abrasive blasters. These machines can perform many procedures other than cleaning, like sectioning, deburring, descaling, stripping and web splitting.
