25–50mm & 50–80mm Industrial Grade Calcium Carbide | 295–315L/Kg Gas Yield | 50kg/100kg Drum | China Plant Direct Sale

As a leading calcium carbide manufacturer and supplier in China, we offer industrial-grade calcium carbide​ in two popular size ranges-25–50mm​ and 50–80mm-with a gas yield of 295–315 liters per kilogram (L/Kg)​ (at STP: 0°C, 1 atm). Packaged in 50kg or 100kg steel drums, our products are engineered for high efficiency, durability, and easy handling​ in acetylene production, steelmaking, and chemical manufacturing. Below, we detail our offerings, specifications, and why our China plant-direct sales model delivers unbeatable value.

1. Product Overview: Dual-Size Industrial Grade Calcium Carbide​

Our calcium carbide is produced in ISO 9001-certified plants​ in China, ensuring consistent quality and compliance with global standards. The two size options cater to diverse industrial needs, while the wide gas yield range (295–315L/Kg) guarantees maximum acetylene output​ per kilogram of CaC₂.

2. Size Options: Tailored for Industrial Applications​

25–50mm Grade​

Ideal For: Medium-scale acetylene generators, welding shops, and steel mills with moderate gas demand.

Benefits: Balanced reactivity-faster than 50–80mm lumps but slower than granules-ensuring steady acetylene flow without pressure spikes.

50–80mm Grade​

Ideal For: Large chemical plants, heavy-duty welding operations, and mega steel mills requiring sustained acetylene output.

Benefits: Slow, controlled reaction minimizes fines generation, reduces reactor clogging, and extends equipment lifespan.

3. Gas Yield: 295–315L/Kg-Maximizing Acetylene Output​

The 295–315L/Kg gas yield​ means 1 kilogram of calcium carbide produces 295–315 liters of acetylene, directly translating to:

Cost Efficiency: Higher yield per kilogram reduces raw material consumption and transportation costs.

Productivity: More acetylene per reactor cycle optimizes plant throughput.

Purity: Low sulfur/phosphorus levels (S≤0.2%, P≤0.15%) ensure clean acetylene for sensitive applications (e.g., PVC production).

4. 50kg/100kg Drum Packaging: Durable & Moisture-Resistant​

Our steel drums are designed for industrial storage and transport:

Moisture Proof: Airtight, rust-proof construction prevents water ingress, preserving gas yield and preventing accidental acetylene release.

Easy Handling: Standardized 50kg/100kg sizes simplify loading/unloading with forklifts or cranes.

Durability: Robust walls withstand rough handling during transit, minimizing product loss.

5. Industrial Applications​

5.1 Acetylene Production​

Chemical Plants: Feeds acetylene reactors for PVC, vinyl chloride, and synthetic rubber manufacturing.

Welding Shops: Powers oxy-acetylene torches for cutting thick steel plates and field repairs.

5.2 Steelmaking​

Deoxidization: Removes oxygen from molten steel to reduce porosity and improve strength.

Desulfurization: Binds with sulfur to form slag, enhancing steel corrosion resistance.

5.3 Foundry Operations​

Mold Strengthening: Added to molten iron to react with silica in sand molds, forming calcium silicate (CaSiO₃) for stronger casts.

6. China Plant Direct Sale: Advantages for Global Buyers​

As a direct manufacturer, we eliminate middlemen to offer:

Competitive Pricing: Factory-direct rates with bulk discounts (5–15% off for 20+ ton orders).

Quality Assurance: Batch-specific gas yield certification and third-party lab testing (XRF, titration).

Flexible Supply: Custom sizes, packaging, and purity levels to match your reactor or furnace requirements.

7. Ordering & Logistics​
