Dissolved Acetylene cylinders for oxy-acetylene cutting, welding, brazing and flame hardening — the hottest and most versatile fuel gas in the workshop, supplied safely across Tinsukia and Upper Assam.
When paired with oxygen, acetylene burns at approximately 3,100–3,300°C — hotter than any other fuel gas combination. That is why oxy-acetylene remains the benchmark for heavy cutting, deep-penetration welding, brazing cast iron and flame-hardening steel components. Nutan Gases supplies Dissolved Acetylene (DA gas) in standard cylinders where the gas is safely dissolved in acetone within a porous mass, making storage and transport stable and compliant with safety regulations.
Fabrication units, auto repair workshops, pipe fitters and maintenance teams across Tinsukia district rely on our DA gas stock because we never compromise on cylinder condition or fill weight. Each cylinder is checked for valve integrity, test validity and correct acetone content before dispatch. Refills are available same-day within Tinsukia town on business days.
| Gas Grade | Dissolved Acetylene (DA) — gas dissolved in acetone within porous mass |
|---|---|
| Standard Size | Typical DA cylinder approx. 40L water capacity (~6–7 kg acetylene) |
| Working Pressure | Filled to ~15–16 bar maximum (acetylene is never compressed above safe limits) |
| Flame Temperature | ~3,100–3,300°C with oxygen (hottest common fuel-gas flame) |
| Valve Type | Standard DA valve with left-hand thread fuel-gas connection |
| Cylinder Colour Code | Maroon body / maroon shoulder (acetylene identification as per IS 4379) |
| Safety Note | Always use flashback arrestors; never use at pressures above 1 bar gauge |
| Refill Turnaround | Same-day within Tinsukia town on business days |

We deliver DA gas cylinders across Tinsukia district and neighbouring towns:
Acetylene becomes unstable above certain pressures, which is why it is dissolved in acetone inside a porous filler mass — never compress or transfer acetylene yourself. Store cylinders upright, away from oxygen cylinders where practical, and always use approved regulators with flashback arrestors on both lines. If a cylinder feels hot or you hear hissing, move away and call us immediately.
Never run acetylene at more than 1 bar gauge working pressure, and never use copper alloys with acetylene (copper forms explosive acetylides) — use steel or brass fittings rated for fuel gas. Our delivery team can check your setup for these common mistakes.
DA (Dissolved Acetylene) is the only safe commercial form of acetylene — the gas is dissolved in acetone within a porous mass inside the cylinder. There is no "regular" compressed acetylene for sale; any cylinder offered as such would be unsafe and non-compliant.
It depends on torch size and usage. A typical cutting tip consumes roughly 1 kg of acetylene per hour of continuous burning; a standard cylinder therefore supports several hours of actual cutting time spread over days of workshop work.
Yes. We can bundle an oxygen cylinder, DA cylinder, regulator set, hoses, torch and flashback arrestors as a ready-to-use package. Call us for combo pricing.
Yes, we accept test-valid cylinders in exchange against our filled stock. Damaged or out-of-test cylinders may need re-testing first — bring it in and we will advise.
