Abrasive water jet cutting method! Nisshin Kiko, with extensive on-site experience, has developed cutting heads and various traversing devices!
The abrasive water jet cutting method involves mixing a special abrasive with water and spraying it at ultra-high pressure to perform cutting! As a pioneer in water jet technology, we have developed cutting equipment and construction methods optimized for various sites and targets, achieving significant results! The pumps we partner with operate at pressures of 200 to 280 MPa. Our self-developed EcoMaster Magnum pump unit is equipped with an engine that complies with low exhaust gas regulations, achieving low noise levels of 75 dB, and is active in various scenes! Due to the minimal vibration generated against the target structure, construction can be carried out even near operating equipment.

basic information
【Features】 - Abrasive WJ cutting is non-flammable and can be performed in areas where open flames are prohibited! - The automatic cutting device "Cutting Traverser" (wrap-around type, suction type) can also handle curved surfaces! - A steel cylindrical structure with a diameter of 3600φ and a thickness of 12t can be cut in just 360 minutes! - The standard cutting nozzle unit allows for continuous cutting with the traverser attached if there is a 300mm gap between the structure and any obstacles behind it. - In the case of a special cutting nozzle unit, cutting from the inside of small-diameter pipes or narrow gaps is possible with an insertion opening of about 100mm! - It can also accommodate cutting through concrete structures along with rebar! - Cutting underwater is also possible. Please use it for designs such as the dismantling of underwater structures. - To reduce shock wave noise, cutting can also be performed by immersing the target object in water.

Applications/Examples of results
【Case Studies/Results】 ○ Cutting of structures at operational steelmaking, petrochemical plants, and power plants. Abrasive water jet cutting is non-flammable and can be performed in fire-restricted areas! ○ Removal of reaction towers and large-diameter piping. ○ A steel cylindrical structure with a diameter of 3600mm and a thickness of 12t was cut in just 360 minutes! Using the "Cutting Traverser" (wrap-around type, suction type). ○ Avoiding interference with the target structural members. The standard cutting nozzle unit allows for continuous cutting with a 300mm gap from the structure and any obstacles behind it. In the case of a special cutting nozzle unit, it can be done with an insertion opening of about 100mm! ○ Cutting concrete structures along with rebar! ○ Dismantling underwater structures. ○ Underwater immersion cutting of objects (reducing shock wave noise).
