Precautions to use a transparent PU duct hose
1. Care must be taken to maintain and use oxygen hoses and acetylene hoses. Keep the hoses clean and undamaged. Avoid sun, rain, snow, and prevent contact with substances that may damage the hoses, such as acids, alkalis, oils, etc. The storage temperature is -15°C~40°C, and the distance should be no less than 1 meter.
2. When a new hose is in use, the talcum powder on the inner wall of the hose must be blown out. Prevent the welding gun channel from being blocked. During use, avoid external pressure and mechanical damage, and do not fold the tube.
3. Oxygen and acetylene hoses must not be mixed and replaced with each other. Do not use the oxygen hose to blow away the blockage of the acetylene hose. At the same time, defects such as leakage and blockage of the welding gun should be checked and eliminated at any time. Prevent the formation of an oxygen and acetylene mixture in the hose. If flashback occurs and fuel enters the oxygen hose, the hose can no longer be used and a new tube must be replaced. Because flashback often burns the regulated inner rubber layer.
Compressed pure oxygen is a strong oxidant. If it continues to be used, normal safety will be lost. Gas cutting operations require a large amount of oxygen output. Therefore, the valve of the earphone (or oxygen pipeline) connected to the high-pressure end of oxygen should be fully opened to ensure sufficient flow and stable pressure. Although the low-pressure gauge has shown the working pressure, the pressure suddenly drops when using oxygen. At this time, flashback is likely to occur, and the oxygen hose may be adjusted to cause an explosion.
