Calcium carbide and acetylene
As a premier chemical manufacturer and exporter in China, Tianjin Zhongying Chemical Co., Ltd. specializes in supplying top-tier calcium carbide and acetylene production solutions to industrial buyers worldwide. Calcium carbide (CaC2) serves as the essential precursor for generating high-purity acetylene gas, a critical component heavily relied upon in metal welding, cutting, steelmaking, and chemical synthesis. Understanding the direct correlation between calcium carbide and acetylene yield, we strictly control our manufacturing processes to ensure that every batch provides maximum efficiency, high stability, and optimal gas output for your operations.

When it comes to generating calcium carbide and acetylene, gas yield and purity are the most decisive factors for industrial efficiency. Tianjin Zhongying Chemical delivers significant advantages that make us the preferred B2B partner globally:
Superior Gas Yield: Our industrial-grade calcium carbide is engineered to deliver a high gas yield of 295 L/KG, ensuring an abundant and continuous supply of acetylene gas while minimizing residue and operational waste.
Tailored Particle Sizes: Different acetylene generators requires specific rock sizes to control the reaction speed. We offer a comprehensive range of fractional sizes, including 1-4mm, 4-7mm, 7-15mm, 15-25mm, 25-50mm, 50-80mm, and 80-120mm. Customized sizing is also available upon request.
Robust and Customized Packaging: Acetylene generation requires perfectly dry raw materials. To ensure complete safety and moisture protection during long-distance ocean freight, we pack our products in brand-new 50kg and 100kg steel drums filled with nitrogen gas. Buyers can fully customize the drum colors (Grey, Black, Yellow, Green, Blue) and print their own shipping marks and company branding directly on the drums.
