There are a wide range of gas products, which generally can be divided into general industrial gases and specialty gases.
General industrial gas production and sales volume, while the purity is not high. Special gas production and sales volume is small, according to different uses of different specialty gases purity or composition, the maximum allowable content of harmful impurities, packaging, storage and transportation products are extremely strict requirements, are high-tech, high value-added products.
In general, specialty gases can be classified into three classes, high or ultra-high purity gases, standard calibration gases, and mixtures of gases with specific compositions. The gas products are widely used in metallurgy, steel, petroleum, chemical industry, machinery, electronics, glass, ceramics, building materials, construction, food processing, medicine and medicine, etc., and are widely used in many industries. Or specialty gases.
