Acetylene, Industrial Grade

Acetylene Industrial Grade — High-Temperature Fuel Gas for NZ Fabrication

Coregas acetylene-industrial-grade is a reliable fuel gas for oxy-acetylene cutting, welding, brazing and heat-forming in workshops and on site. Supplied as a dissolved gas in cylinders, it delivers a hot, concentrated flame for fast preheat, clean pierce and efficient metal removal when paired with oxygen (process set-up as per your WPS and OEM torch data).

Why Coregas for Industrial Acetylene

• Consistency & availability: NZ-wide supply with dissolved-gas cylinders for safe handling and transport.
  

• Application support: Guidance on regulators, flashback arrestors and hose sets to match flow and pressure requirements. Never open a cylinder without a regulator attached; use equipment compatible with acetylene.

• Closed-loop stewardship: Return cylinders to Coregas for contents disposal/end-of-life.

Safety & Handling Essentials (Summary)

• Hazards: Extremely flammable; may react explosively even without air; gas under pressure (dissolved). Asphyxiant if oxygen is displaced.
  

• Prevention: Keep away from heat/sparks/open flames; no smoking; follow site controls.
  

• Storage: Protect from sunlight; store upright, restrained, below 65 °C in a dry, well-ventilated non-combustible area; keep away from traffic/exits.
  

• First aid: Treat for asphyxia if exposed to high concentrations.
  

• Fire response: Cool cylinders from a protected location; do not extinguish a leaking-gas flame unless the leak can be stopped safely; Hazchem 2SE.
  

• Compatibility: Avoid copper alloys >65 % Cu, silver and mercury (risk of explosive acetylides).

• PPE & ventilation: Provide suitable ventilation; wear eye protection and gloves; SCBA/Air-line in confined spaces per risk assessment.

Transport & Classification

UN 1001 — ACETYLENE, DISSOLVED; Dangerous Goods; Hazchem 2SE. Follow NZS 5433 and internal transport SOPs.

FAQs — Industrial Acetylene

Is industrial acetylene a “dissolved” gas? Yes. The product is supplied as a dissolved gas in cylinders, classified as a gas under pressure (dissolved).

What fittings should I avoid? Avoid using copper alloys above ~65 % Cu, silver or mercury, due to the risk of forming explosive acetylides.

Can I fully shut off a leaking acetylene flame? Only if you can safely stop the leak; otherwise do not extinguish—cool the cylinder from a protected area and await emergency support.

How should cylinders be stored? Upright, restrained, ventilated, below 65 °C, away from ignition sources and traffic routes, with “No Smoking/Open Flames” signage.

Health effects to plan for? Acetylene is an asphyxiant at high concentrations; plan ventilation and rescue per confined-space rules.

End-of-life—what do we do? Return cylinders to Coregas for contents disposal.
