Water jetting is a technology used to clean and prepare surfaces in various industrial applications. It is a very flexible technology that is used for some chemical industry and ship hull.
This process is environmentally and friendly and does not generate hazardous material that are usually found in manufacturing processes. It also makes use of minute amounts of water that can be recycled within the looped system. With this technique, corrosion and the release of contaminants from industrial materials can be minimized.
Water jetting equipment makes use of ultra-high pressure that is nonabrasive inside. It is an efficient and suitable technique for removing corrosion products such as rust from different surfaces like metal. Rust is a product of the contact of steel or iron with oxygen and water through a process called oxidation corrosion. Rust is a major destructive force leading to tremendous damage to materials and poses safety risks.
Water jetting is the best way for rust and paint removal
Thus, corrosion should be mitigated, especially in the sensitive areas of any industrial equipment, systems and operations. One of the devices used to counter rust are water jetting machines that utilize high-pressure along with pure water to initiate the cleaning. There are no other materials involved such as aluminous abrasives, glass beads or bicarbonates.
Water jetting can be very beneficial in eliminating rust from larger areas. Using other methods like blasting using grit can be more costly, while brushing off through mechanical means is not that efficient due to its poor coverage.
While , except remove the rust with the pressure more than 1500 bar , sometimes it is widely used for ship hull to remove the paint from the metal sheet ,like the big shipping ,there are lots of the alga and oyster stick to the surface of the ship , it need ultra high pressure water jetting those material and the pressure need up to 2800 bar .
Most importantly, water jetting provides more versatility, as through this method, the surfaces that are cleaned are also being prepared for painting or repainting.
