From crates on site to certified first fill

Acetylene Plant Start-up & Commissioning Services

The distance between equipment delivered and a plant safely filling cylinders is where projects succeed or fail. IIGAS commissioning engineers take acetylene and industrial gas plants through erection, testing, first carbide charge and performance trials to certified production — for our own plants and for plants of any make, worldwide.

Remote, on-site, or both

We offer commissioning three ways. Remote support guides your team through pre-commissioning — foundations, utilities, piping schedules and pre-checks — by video and documentation before an engineer travels. On-site service puts IIGAS commissioning engineers at your plant through erection supervision, testing, start-up and operator instruction. Most export projects combine the two: remote preparation so the on-site days are short and productive.

What IIGAS commissioning covers

  • ✓Erection and installation supervision against the approved plant layout
  • ✓Pneumatic leak testing and pressure testing of every circuit
  • ✓Nitrogen purging of generators, purifiers, driers, compressors and lines
  • ✓Instrument loop checks — pressure, temperature, level transmitters and controllers
  • ✓Safety interlock and alarm trials: high/low water, high temperature, back-pressure protection
  • ✓Flashback arrestor and relief valve verification
  • ✓First carbide charge and controlled start-up of the generator
  • ✓Gas purity testing and compressor performance trials
  • ✓DA cylinder filling trials to full working pressure
  • ✓Handover documentation, operating manual and log/checklist system

Why commissioning by the plant builder matters

Acetylene leaves no margin for guesswork at start-up: the first carbide charge, the first compression run and the first cylinder fill must each happen under controls that assume something will go wrong. Our engineers commission to NFPA 51A, CGA, EIGA and IS 8471 practice — the codes our team helps maintain on the BIS committees CHD 6 and MED 16 — and they commission plants they understand from the drawing board, having built hundreds since 1947 and commissioned them in 20+ countries.

We also re-commission: plants that have been relocated, idle plants returning to service, and plants after major upgrades — each gets the same full test-and-trial sequence before production resumes.

Frequently asked questions

Yes. We commission and re-commission acetylene and industrial gas plants of any make — including relocated plants, idle plants returning to service and plants after major upgrades.
Erection supervision, leak and pressure testing, nitrogen purging, instrument loop checks, safety interlock trials, first carbide charge, purity and performance trials, DA filling trials, and handover with documentation and operator instruction.
Typically one to three weeks on site depending on plant capacity and site readiness; remote pre-commissioning support shortens the on-site phase. We confirm a schedule with your proposal.
Yes — IIGAS engineers have commissioned plants in 20+ countries across Asia, the Middle East, Africa and the Americas, with remote support before and after the visit.
Initial operator instruction during trials is part of commissioning; full structured training is available as a dedicated on-site programme.
