Silicone hose sleeve offers you excellent hose protection solution
Oxygen hoses and acetylene hoses come in different colors and have different working pressure standards. Oxygen hoses operate at higher pressures than acetylene hoses. Therefore, the oxygen hose should be stronger. As standard, oxygen hoses are blue and acetylene hoses are red. The working pressure of the oxygen hose is 1.5MPa. The inner diameter of the hose is 8mm and the outer diameter is 18mm. The acetylene hose is black and the working pressure is 0.3MPa. The inner diameter of the hose is 8mm and the outer diameter is 16mm.
Welding hose three-color:
Red and green: red is oxygen hose, green is acetylene hose
Black and red: red is oxygen hose, black is acetylene hose
Red and blue: red is oxygen hose, blue is acetylene hose
Safety precautions for oxygen and acetylene hose
Hose joints and pipes should be strictly prevented from leaking. Oxygen and acetylene hoses should be blown clean before connecting. Make sure there is no water in the hose before use. Do not use oxygen to blow out blockages in acetylene gas hoses. Prevent the formation of a mixture of oxygen and acetylene in the hose.
If the acetylene hose falls off, breaks or catches fire during use, the welding torch flame should be extinguished first and then the gas supply should be stopped.
Acetylene and oxygen hoses should avoid contact with grease or metal solutions during operation
Avoid exposing acetylene and oxygen hoses to sunlight, high temp baking, rain and snow. Besides, prevent acid, gas, oil and organic solvents from contacting the hoses
A leaking hose should not be repaired but should be shortened to remove the damaged section. Shortening and modification should be done using proper and correct tools and equipment designed for the task. Screw-tight crimpers should not be used. Because their use increases the risk of leakage due to over-tightening
