SIL medical gas cylinders are manufactured with extra quality inspection stages to ensure that cylinder have smooth and clear international surfaces to save oxygen and other medical gases from contamination. As part of medical use, external surface has been coated with good quality epoxy paint and also adhere to the stringent national and international standards. Gases like oxygen and nitrous oxide are extensively used in the health care business for patients who need help breathing, for administering anesthesia during operations etc. So cylinders not only need to be safe, they have to be free of containments as well.

SIL’s high-pressure industrial gases cylinders – for oxygen, hydrogen, nitrogen, argon, helium, air etc – are designed to withstand such rough handling. For one, they are made of high-quality seamless steel tubes using state-of-the-art CNC machines. What’s more, we adhere to the most stringent regulations — both national and international — while manufacturing them. Cylinders for the domestic market are produced as per IS-7285, certified by the Bureau of Indian Standards (ISI) and approved by the Chief Controller of Explosives, Government of India.

The gas industry relies heavily on cylinders to store and transport gases. Because the cylinders are packed with gases under high pressure, they can be volatile. So they must be tough enough to withstand rough handling during transportation to prevent accidents. SIL’s high-pressure industrial gases cylinders – for oxygen, hydrogen, nitrogen, argon, helium, air etc – are designed to withstand such rough handling. For one, they are made of high-quality seamless steel tubes using state-of-the-art CNC machines.

Cylinders for the domestic market are produced as per IS-7285, certified by the Bureau of Indian Standards (ISI) and approved by the Chief Controller of Explosives, Government of India. And there’s a range of products to meet every need, whether small or large. We provide cylinders with water capacities that range between one liter and 280 liters, and also supply the size you need on request. Because we are flexible enough to meet any specification, many countries have approved the use of Sarju cylinders.

SIL has aimed at maintaining the highest standards of operations for its fire fighting cylinders. Sarju Impex Ltd has deployed hot spinning technology for closing seamless tube at both ends. The Equipments for manufacturing Fire fighting CO2 gas cylinders have been source from suppliers who are world leaders in their respective fields.   CO2 extinguishes fire by reducing the oxygen content of the protected area below the point where it can support combustion. CO2 fire extinguishing systems typically store the agent in one of the two different ways: High Pressure Cylinders & Low Pressure Cylinders. SIL is one of the leading manufacturer of high-pressure gas cylinders, offering an expanding range of high-quality lightweight CO2 cylinders that can be used for hand-held and portable wheel-type fire extinguishers The large cylinders can be used for system fire extinguishers that use CO2, Halon, FM-200 and NAF-S-II & III gasesFire fighting CO2 gas cylinders, medical gas cylinders, in India.  

SIL provides a wide range of CNG cylinders that are designed and manufactured to comply with the highest national and international standards like ISO, EN, IS, BS, NZS AND D.O.T. and any other International Standards. We have high-quality seamless steel CNG cylinders for almost all kinds of vehicles, like three-wheelers, cars, buses and delivery vehicles.   SIL CNG cylinders are strong and lightweight and undergo stringent cyclic testing to assess fatigue strength, usage life and to ensure safety and reliability under extreme climate conditions. We supply the cylinders according to customer specifications and requirements. The CNG tanks are manufactured to tolerate a working pressure of 200 bar. Various CNG cylinders are available with different diameters and lengths and produced in various specifications, according to the technical features required by different countries. All cylinders are epoxy-coated on the outside to offer protection against rough handling. Please see the table below for details. If you need more information, please feel free to contact us at

SIL makes thick-walled shells for hydraulic accumulators – mainly bladder type with the working pressures are up to a maximum of 330 bars and test pressures are up to 500 bars — for various type of industrial uses and requirements. The accumulators have been designed to meet the highest safety standards, and are capable of withstanding millions of duty cycles of pressurization..   There has been a dramatic growth in industrial hydraulics applications because of increasing automation, and the need for reliable, compact force elements. And hydraulic accumulators are widely used in industrial hydraulics to dampen shocks, and save energy by downsizing the prime movers.   The product is available in varying diameters (76-407 mm), lengths (200-2,500 mm) and preferred diameters (90 mm, 114 mm, 168 mm, 220 mm). The shells are also designed and manufactured to comply with international standards and our in-house standards are on a par with those of reputed global manufacturers of hydraulic accumulator assemblies.   The material used in accumlators construction include chromium molybdenum steel, nickel chromium molybdenum steel, carbon manganese steel, carbon steels and stainless steel as per customer requirements.
