Oxygen O₂Supplier & Manufacturer in India

Industrial & liquid oxygen for cutting, steel and combustion.

Formula: O₂Purity: 99.5%+ (industrial)Appearance: Colourless, odourless gas
O₂

High-purity industrial oxygen supplied in high-pressure cylinders and as liquid oxygen (LOX) in cryogenic tankers — the workhorse gas of metal cutting, steelmaking and combustion.

Oxygen (O₂) is a colourless, odourless gas that supports combustion and oxidation, making it indispensable across heavy industry. International Industrial Gases Ltd manufactures industrial oxygen by the cryogenic distillation of air in our air-separation plants, then supplies it as compressed gas in cylinders and cylinder banks, or as liquid oxygen (LOX) delivered by insulated road tankers and stored in vacuum-insulated tanks.

In metal fabrication, oxygen mixed with acetylene or LPG produces the high-temperature flame used for oxy-fuel cutting, welding and brazing. In steelmaking, oxygen lancing and enrichment raise furnace efficiency in both basic-oxygen and electric-arc routes. Oxygen is equally vital to glass melting, chemical oxidation, effluent and waste-water treatment, ozone generation and aquaculture.

Every batch is produced to consistent purity with full quality control. IIGAS supplies industrial oxygen at 99.5% and above, with higher-purity and specialty grades available on request, backed by reliable cylinder logistics and bulk delivery across India.

Frequently asked questions

Industrial oxygen is used for oxy-fuel cutting, welding and brazing, oxygen lancing and enrichment in steelmaking, glass melting, chemical oxidation, effluent and waste-water treatment, ozone generation and aquaculture.
We supply industrial oxygen at 99.5% and above, with higher-purity and specialty grades available on request. Medical oxygen is offered separately to Indian Pharmacopoeia (IP) standards.
Yes. Liquid oxygen is delivered in cryogenic road tankers and stored in vacuum-insulated tanks for high-volume users, while cylinders and cylinder banks serve smaller demand.
Oxygen is produced by the cryogenic distillation of air in air-separation units, and by Pressure Swing Adsorption (PSA) for on-site generation.
Oxygen is supplied in 47 L water-capacity cylinders (about 7 m³ at 150 bar), in cylinder banks/quads, and in bulk as liquid oxygen.
Oxygen is not flammable itself, but it vigorously supports combustion. Keep cylinders away from oil, grease and ignition sources, and use only oxygen-clean equipment.
Our oxygen complies with IS 309 and CGA/EIGA practice, manufactured under strict quality control with batch traceability.
Store upright in a cool, ventilated area away from fuels and oils, secured against falling, with valve caps on when not in use.
Yes — from our Howrah head office and manufacturing works, our gas plant and branch in Madhya Pradesh, and our depots in Assam and Uttar Pradesh, we deliver cylinders and bulk liquid oxygen across India with dependable logistics.
