For over a decade, industrial manufacturers across Asia, Europe, and the Middle East have relied on high-purity calcium carbide from Longwei Chemical—a trusted supplier based in Ordos, Inner Mongolia—to power their welding and cutting operations. Why? Because this versatile chemical doesn’t just meet standards—it exceeds them.
When calcium carbide (CaC₂) reacts with water, it produces acetylene gas—a clean-burning fuel used in oxy-acetylene torches for precision cutting and welding. In fact, 78% of global metal fabrication shops still use acetylene as their primary cutting gas due to its consistent flame temperature (~3,500°C).
Our production facility in Ordos ensures a purity level of ≥92%, which means fewer impurities in the gas stream—resulting in smoother cuts, less post-processing time, and improved weld quality. Compared to lower-grade alternatives, our product reduces gas waste by up to 15% per batch, according to field tests conducted at three major steel plants in China.
| Application | Performance Gain |
|---|---|
| Metal Cutting | Up to 20% faster cut speed |
| Welding Stability | Reduced spatter by 30% |
| Steel Desulfurization | Improves steel quality index by 12% |
A leading German manufacturer reported a 17% drop in rework costs after switching to Longwei’s calcium carbide. “The consistency in gas output allowed us to reduce manual adjustments during cutting,” said Martin Weber, Head of Production at Hessen Metall GmbH. “We’re now using 5% less gas per ton of steel processed.”
This isn’t an isolated case. Over 200 B2B clients—from small welding shops in Dubai to large-scale foundries in Brazil—have adopted our product for its reliability, safety compliance, and scalable supply chain.
We don’t just sell chemicals—we build relationships rooted in transparency, safety, and performance. Every shipment undergoes rigorous QA checks, and we provide full traceability documentation upon request. Our team is available 24/7 via email or live chat to answer technical questions before, during, and after your order.
