What does KIGL manufacture?

Two things. KIGL fills industrial and medical gases into cylinders at its own works, and designs and builds acetylene gas plants and safety equipment. The combination is unusual: most gas companies do not build plant, and most plant builders do not operate one daily.

Which areas does KIGL supply?

Cylinder gas is filled at KIGL's own works in Guwahati and serves Assam and the North-East directly. Beyond that it reaches customers through a network of agents across Uttar Pradesh, Madhya Pradesh, West Bengal, Assam, Odisha and other states. Equipment — acetylene plants, flashback arrestors, accessories — ships anywhere in India, including all seven North-East states, West Bengal, Uttar Pradesh, Madhya Pradesh, Chhattisgarh, Bihar and Odisha.

Does KIGL supply liquid oxygen and liquid nitrogen?

Yes, both. The distinction matters: KIGL manufactures compressed and dissolved gases at its own filling plants, and operates an air separation plant for oxygen and nitrogen. Helium is supplied rather than manufactured, as no one manufactures helium in India.

How old is the company?

The company began in 1947 as The Industrial Gases Limited, among the earliest industrial gas manufacturers in India. In 1988 the company was divided into several businesses, and The Kamrup Industrial Gases Limited was formed, led by Devendra Kumar Garg, with IGL's plant designs, staff and know-how. That is seven decades of continuous manufacture, now under the fourth generation of the founding family.

Can KIGL help with PESO licensing and compliance?

For equipment KIGL supplies, yes: KIGL provides the drawings and equipment certification needed to support an application under the Gas Cylinders Rules, 2016, and advises on the Calcium Carbide Rules where carbide storage is involved. The licence itself is held by the operator.

How do I get a quotation?

State the gas or equipment, the quantity or capacity, and the delivery location. For gas, KIGL will confirm whether that location is served from the Guwahati works or through an agent. Plant and equipment are quoted anywhere in India.

The Kamrup Industrial Gases Limited

Industrial gases and acetylene plants, manufactured in India since 1947

KIGL fills dissolved acetylene to IS 308, along with oxygen, nitrogen, argon, CO₂ and medical gases, at PESO-approved works in Guwahati, and builds acetylene plants, PSA plants, flashback arrestors and pipelines at Kolkata. Few suppliers do both, so plant advice comes from people who fill cylinders from one daily.

It is a fuel that turns dangerous in air. Acetylene comes apart under pressure with no oxidant at all — and everything unusual about handling it follows from that one fact.

Standards

Indian Standards for industrial gas, written from the inside

Devendra Kumar Garg, who founded KIGL, has sat on the Bureau of Indian Standards committees that write India’s acetylene and gas cylinder standards since the 1970s, and chaired the subcommittee for dissolved acetylene cylinders and generators when the acetylene pipeline codes, IS 15190 : 2002, were drafted.

Acetylene cylinder handling — golden rules

Never exceed 0.62 bar g: The IS 14814 : 2023 limit for free acetylene; 1.03 bar g only with PESO clearance
Cylinders upright, always: Stops acetone being drawn off with the gas
Arrestors at regulator and torch: Valve open no more than 1.5 turns
No copper, no oil, no grease: Copper forms explosive acetylides

Manufacturer and plant builder

KIGL builds the plant, and then runs it

Since 1947 KIGL has designed and built gas plant at Kolkata, and filled cylinders daily on that same equipment at its Noonmati works. What the filling floor teaches goes back into the next plant KIGL builds, and plants delivered decades ago are still in service. Four generations of the founding family have run these works, and the family has served on the Bureau of Indian Standards gas cylinder committees since the 1970s.
