Optimal reaction equilibrium: Steady gas generation without pressure surges or generator residue clogging. Guaranteed Gas Yield ≥ 295 L/kg.
The 20–40mm mesh size is the most widely specified raw material for commercial gas refilling stations and metal fabrication shops. It solves the two biggest headaches in gas production:
No Pressure Surges: Unlike fine powder, 20-40mm lumps do not dissolve instantly, preventing dangerous pressure spikes in hopper-fed generators.
Zero Pipe Blockage: Large enough to stay in the reaction grate while slowly dissolving, eliminating lime-slurry choking and downtime.
Maximizing Cylinder Yield: Delivers a steady, predictable gas curve ideal for compressing standard oxy-acetylene welding cylinders.
1 Metric Ton of 20–40mm CaC2 (≥295 L/kg) = Approx. 295 m³ Pure Acetylene Gas
(Sufficient to fill approximately 45–50 standard 6.0m³ acetylene gas cylinders)

Precautions
Inspection upon Receipt
-Inspect drums upon receipt, paying attention to moisture (e.g., snow, ice shouldbe removed before storage).
-Check for signs of swelling, heat, or mechanical damage.
Handling Hot Drums
-If a drum is hot, do not cool it with water, and do not move the drum until it hascooled completely.
-The area should be cordoned off, and entry restricted until the drum cools.
Opening the Drum
-Use non-sparking tools (e.g,, brass hammer) to open the drum in a designatedarea.
-Ensure drums are opened only immediately before the calcium carbide is requiredfor use.
Personal ProtectiveEquipment
-Wear personal protective equipment (PpE), including gloves, helmets, and faceshields when opening drums and handling calcium carbide.
Transferring Calcium Carbide
- Use a charging skip or specialized transfer equipment, ensuring proper groundingduring transfer.
-All transfer tools should be equipped with gas-purging systems and anti-staticproperties.
Cleaning up Spillage
-Use natural fiber brooms and non-sparking tools to sweep up any spillage during transfer.
-Calcium carbide dust should be disposed of safely.
