7-15mm Calcium Carbide – Reliable Choice for Welding Shops & Medium Generators
Straight from our Inner Mongolia plant
We manufacture calcium carbide in our own facility – 70,000 tons per year. Our warehouse is less than 5 km from Tianjin port, which means your 7-15mm calcium carbide order leaves quickly, usually within two weeks after deposit. We test every batch for gas yield (280–285 L/kg) and low impurities. No third‑party blending.
Why 7-15mm hits the sweet spot
Smaller than 15‑25mm but larger than 4‑7mm – this granulation offers a balanced reaction rate. It doesn't produce excessive dust like fine powders, yet it dissolves faster than big lumps. That's why medium‑scale acetylene generators and welding shops prefer 7-15mm calcium carbide. It feeds reliably through standard screws and gives a steady flame for cutting and brazing.
Common uses:
-
Acetylene generators for small‑to‑medium metal fabrication shops
-
Portable welding kits (mining, construction sites)
-
Chemical labs needing controlled gas release
-
Backup carbide lamps in remote areas
Packing – two drum options, same container total
Each 20' container holds exactly 22.5 net tons of 7-15mm calcium carbide:
Drums are nitrogen‑sealed, UN‑approved (UN1402, Class 4.3), and labeled with moisture warnings. Stackable without pallets.
