WHAT IS CNG Treated Gas? It is an CNG Mixture for high combustion with Compound of Methane, Ethane and other hydrocarbons for oxy fuel cutting. It does faster and clean jobs of metal cutting, Brazing, Gouging and flame hardening. It stored & distributed in hard containers at 180~ 200 bar. Cost Significantly less than other Gases. It is more safer and it gives better cutting performance than acetylene. Properties of CNG Treated Gas Appearance : Colourless Gas Odour : Pungent Odour – Mercaptan mixture ( added) Heat of Combustion : 21003 BTU/ LB Auto ignition temperature : > 530 ° C Flammable limit : LEL = 4.5 % Vol Flash point : -184° C Vapour Density : 0.80kg/ m3 @ 760 mm Hg BENEFITS OF CNG TREATED GAS 1. Quicker Start time due to concentrated of high Temperature. 2. 5 – 10 % faster cutting speeds on straight Cutting. 3. 10 – 20 % faster cutting speeds on shape cutting. 4. Extremely clean burning. 5. Less carbon. 6. Use maximum 98 % volume of container. USED OF CNG TREATED GAS 1. BRAZING Flame is clean in such way zero porous bond produced. No finishing required in brazing copper to copper, using flux, as the surface of the heated metal is clean and shiny. 2. CUTTING Cut steel faster than other gases. Less carbon slag and no weld-back due to complete oxidation, hotter flame. Little or no grinding required after cutting. 3. FLAME HARDENING Faster flame hardening due to high temperature, Superior heat transfer properties and stability of CNG. Permits greater line pressure for an enlarged flame. 4. GOUGING Quality speed gouging operations. Less Slag and weld-back free gouging process with parent metal exposed ready for welding.
