Advantages Of Water Jet Cutting Over Conventional Gas Cutting
| Hazards | Conventional System - Gas Cutting | Ultra High Pressure Water Jet Cutting |
|---|---|---|
| Explosive or by gas leak | LPG and other fuel gases are explosive mixture with air and tanks due to hot work. Cause in gas pipeline and oxygen. Fire/explosion can highly flammable and form. | Water and fine abrasive materials used for Cold Cutting which helps to keep the cutting temperature under the LEL. |
| Black fire & flashback | This is a common problem in case of conventional gas cutting. | The issue is totally eliminated. |
| Health Hazards | Fumes created during gas cutting, particles generated during the gas cutting create health hazards like lung cancer. | No emission of fumes. |
| Fire/Burns misuse of oxygen | Oxygen leakage create fire hazards and O2 is costly. | Oxygen is not used; water is cheap. |
| Crushing & impact injury | Prevent cylinders from falling or being knocked over by securing them with a stout chain or strap. | No usage of heavy cylinders; cutting setup is fixed on the cut piece itself. |
| Man-machine interference | People work closely with cutting machine and cutting objects. | Remote operated-cold work. |
