7-15 mm Calcium Carbide – The Balanced Granule for Reliable Acetylene Production

We are one of the experienced calcium carbide manufacturers in china. Our factory is in Inner Mongolia, where raw materials are abundant. Our warehouse is in Tianjin, less than 5 km from the port. That location means we can ship faster than many other calcium carbide manufacturers in china. And because we control production from furnace to drum, we can offer real customization – not just standard packs.

What You Get From Our 7-15 mm Grade

• Gas yield: 250-265 L/KG (batch tested)

• Appearance: Clean, angular granules, minimal dust

• Reaction speed: 60‑120 seconds in standard acetylene generators

• Best for: Medium-scale acetylene plants, chemical batch reactors, continuous desulfurization

We also produce every other size: 1‑4 mm, 4‑7 mm, 15‑25 mm, 25‑50 mm, 50‑80 mm, and 80‑120 mm. All from the same high-quality calcium carbide base. That makes us a flexible choice among calcium carbide manufacturers in china – because we don’t force you into one size per container.

One Container – Mix Any Sizes, Each in Its Own Drum Color

Most calcium carbide manufacturers in china will tell you “no” when you ask to mix sizes. Too much hassle, they say. We say “yes” – and we do it every week.

Here’s a real example from last month:

• 8 tons of 7‑15 mm → Orange drums

• 5 tons of 25‑50 mm → Red drums

• 4 tons of 4‑7 mm → Green drums

All in one 20' container. Total 17 tons. Your warehouse team sees orange and immediately knows: “That’s the 7‑15 mm batch for Generator #2.” No label reading. No confusion.

We have 11 standard drum colors (RAL shades). Or send us a color code and we’ll match it. No extra charge.

Your Own Markings  – Printed, Not Stickered

We don’t use cheap adhesive labels that peel off in humid conditions. We paint your markings directly on the drums. You provide a PDF or AI file. We proof it with you, then apply it.

What can we print?

• Your company logo

• “Calcium Carbide – 7‑15 mm – 292 L/KG (typical)”

• Net weight: 50 kg or 100 kg (we offer both drum sizes)

• Batch number and production date

• “DANGER: Reacts with water. Flammable acetylene gas.”

• UN1402 / Class 4.3 hazard diamond

• Consignee details or destination port

• Local language warnings – we’ve done Thai, Arabic, Spanish, French, Vietnamese, and Indonesian

Mixed Drum Weights – 50 kg and 100 kg in the Same Box

Not every site has a forklift. Your main plant might use 100 kg drums. A smaller line or a remote warehouse might need 50 kg drums because workers lift them by hand. We can load both into one container.

Example: 10 tons of 7‑15 mm in 100 kg drums (100 drums) plus 4 tons of 15‑25 mm in 50 kg drums (80 drums). Same shipment, one freight bill, two drum sizes. That’s the kind of flexibility you don’t get from every calcium carbide manufacturers in china.

How We Pack and Load

Standard loading: 22.5 tons per 20' container. Drums are strapped, braced, and palletized. Each pallet has a colored band matching the drum color. You’ll receive a detailed packing list showing exactly how many drums of each size, color, and weight are inside.

If you need less than a full container, we can do LCL (less than container load). Just ask.

Storage – Keep It Dry for Up to 2 Years

Calcium carbide hates moisture. Even humidity can slowly degrade it, producing acetylene gas inside a sealed drum. That’s dangerous.

Follow these rules:

• Store off concrete floors – use pallets or steel racks (concrete wicks moisture).

• Keep temperature below 40°C and humidity under 50%.

• Never stack drums under water pipes, sprinklers, or leaking roofs.

• Reseal drums immediately after removing product. Don’t leave them open.

If you store our 7‑15 mm correctly – dry, cool, off the floor – it stays effective for up to 2 years. In humid tropical areas (like Indonesia or Nigeria), we recommend using within 12‑18 months.

Where Do Customers Use 7‑15 mm?

We export to over 45 countries – Vietnam, Thailand, Philippines, Brazil, Egypt, Poland, Turkey, and many more. Common applications for 7‑15 mm calcium carbide:

• Medium-scale acetylene generators – the size balances feed rate and reaction time.

• Steel desulfurization – some injection systems prefer this granulation for even dispersion.

• Chemical synthesis – producing acetylene derivatives like vinyl chloride or acetaldehyde.

• Calcium cyanamide production – the granules react consistently in rotary kilns.

Safety – No Jokes, No Shortcuts

I have to be direct. Calcium carbide + water = acetylene gas. Acetylene + spark = explosion. Never open a drum in rainy weather. Never use water to clean a spill (use dry sand or an inert powder). If a drum gets wet by accident, do not move it – evacuate the area and call emergency services.

We put clear warning labels on every drum. But you must train your warehouse and production staff. One mistake can cost lives.

Certifications – We Ship Anywhere

We are not a backyard operation. Among serious calcium carbide manufacturers in china, we stand out for our documentation. Available certificates:

• ISO 9001 (quality management)

• SGS inspection reports (pre-shipment or upon arrival)

• BV (Bureau Veritas)

• REACH (for European buyers)

• Full SDS in multiple languages

• GHS-compliant drum labels

• Origin certificate, commercial invoice, packing list, bill of lading

Need a specific third-party inspection (Intertek, TÜV, Cotecna, etc.)? Just tell us. We’ve handled requests for Kenya, Bangladesh, Indonesia, Nigeria, and many other countries.

Why Choose Us Among All Calcium Carbide Manufacturers in China?

Honestly? Because we listen. You tell us: “I need 7‑15 mm in orange drums, 50 kg each, with my logo in Thai, plus 5 tons of 25‑50 mm in red drums, 100 kg each, mixed in the same container.” We say: “Send us the artwork. Here’s the quote. Let’s load.”

No traders. No middlemen. No copy-paste answers. Just people who know calcium carbide and know how to pack it the way you want.
