Nitrogen (N2)

Argon is one of the Noble gases. It is a colourless and odourless gas which is inert to other substances. Argon finds diverse applications across various industries, with its primary use as a shielding gas in arc welding, either in its pure form or as part of different mixtures. Additionally, it is a key component in the filling mixtures for incandescent lamps, phosphorescent tubes, and thyratron radio tubes. In the iron, steel, and heat treatment industries, Argon plays a vital protective role, especially for metals prone to nitriding when exposed to a nitrogen-based atmosphere. Argon serves as a carrier gas in various applications such as chromatography, sputtering, plasma etching, and ion implantations. It plays a crucial role in creating a protective atmosphere in crystal growth, viniculture, and pharmaceutical packaging. In the case of excimer lasers, argon is combined with fluorine and helium. Additionally, as an insulation gas, argon is commonly utilized to enhance thermal insulation in multi-pane windows.

We are a well-established supplier of Acetylene gas in Mumbai, also known as D A Gas. This hydrocarbon, recognized for its colorless properties, serves as a crucial fuel gas in various industries, particularly for applications such as metal cutting and brazing. When combined with Oxygen, Acetylene generates the highest flame temperature. Its commercial production involves the reaction of Calcium Carbide with water. Due to its inherent instability, Acetylene is stored in gas cylinders pre-saturated with a specified amount of the solvent, either Acetone or DMF, as a safety measure.

Common Uses in Industries

• As a flame cutter for metal cutting/welding / brazing purposes.
• As a lighting lamp in mines and caves.
• As a carburizing agent / hardening agent in the steel industry.
• As a gas in AAS – Atomic Absorption Spectroscopy.
• Some of the pharmaceutical industry also uses Acetylene dissolved in DMF.

Hydrogen (H2) is a gas without odor, color, or taste, generated through either natural gas steam reforming or water electrolysis. Being lighter than air, it produces a clean and invisible flame without carbon or soot. Notably, hydrogen is the sole fuel gas devoid of carbon atoms. It boasts the highest thermal conductivity among all gases. When combined with oxygen, the hydrogen flame achieves a temperature of 2834°C. It is often mixed with argon to create a range of argon/hydrogen shielding gases for TIG and plasma welding. These shielding gas mixtures are primarily used for welding austenitic stainless steels and some nickel alloys. Hydrogen can also be used with argon in a range of gas mixtures for plasma-cutting (stainless steel and aluminum mainly). Hydrogen extends its utility far beyond being a fuel gas, finding diverse applications in the manufacturing of carbon steels, special metals, and semiconductors. Within the electronics sector, it serves as a prevalent reducing agent and carrier gas. Additionally, high-purity hydrogen plays a crucial role as a carrier gas in gas chromatography. In addition, it can be combined with oxygen for underwater flame-cutting. Deeper cutting applications require higher fuel and oxygen pressures. Hydrogen is ideal here as it is supplied at higher pressures than other fuel gases. In the glass industry, hydrogen is used to form the rim on glasses.
