Q: Where is your plant located?
A: Our calcium carbide factory is located in Inner Mongolia, which is near carbide raw material place. It covers an area of 5000 aquare meters.With monthly production capacity of 6000 tons.
Q: How can you guarantee the quality?
A: We will take a lot of sampling testing second time during carbide processing to ensure products with good gas yield.
We often do air pressure testing to drums, ensure carbide drums seals tight and safety.
Different sizes stored separately to avoid size mixing.
We will take sampling test again before goods loading, ensures loaded goods with correct weight, sizes, gas yield and quantity.
Our carbide Production is based on Chinese National Standard: GB10665-2004.
Q: What is the gas yield?
A: Typically, the gas yield of the particle size 80-120mm, 50-80mm, 25-50mm is 295L/KG.
The relationship between the gas yield and calcium carbide is as following. | ||||||||
CaC2 (%) | 63.14 | 68.52 | 72.54 | 73.89 | 75.2 | 76.57 | 77.91 | 80.6 |
Gas Yield(L/Kg) | 235 | 255 | 270 | 275 | 280 | 285 | 290 | 300 |
Q: What is the delivery time?
A: It is usually within 20 days after receiving the deposit or original L/C.
