      PropaneCutting gas characteristicsPropane:Through the treatment of propane gas, propylene gas,Acetylene gasThe experimental comparison and theoretical discussion of the three gases clarified that the new type of cutting propane gas has the characteristics of high efficiency, low cost, safety, and environmental protection.
      When propane gas is used for steel plate cutting, the cutting cost varies with the thickness of the plate. When used for thick steel plate cutting, the cost savings are significant, and it is suitable for the cutting of scrap steel.
      The types of gas used in production and their main properties are shown in the table. In the past, acetylene was used the most. In recent years, due to the low price of propane, safe use and sufficient gas source, the overall effect is better than that of acetylene and other gas, so the consumption is greatly increased.
