Anhydrous Calcium Chloride 94% Flake And Pellet for Oil Drilling
Anhydrous Calcium Chloride is an industrial-grade inorganic salt available in flake and pellet form, with purity levels of 94% and above. It is produced through the reaction of hydrochloric acid with calcium carbonate, followed by high-temperature dehydration. The product contains minimal moisture and delivers consistent performance in moisture-absorption and exothermic applications.

Applications and Usage
In oil and gas drilling, anhydrous calcium chloride is used to prepare completion and workover fluids with density ranges of 1.30–1.50 g/cm³, helping control formation pressure. In construction, it accelerates cement setting in cold-weather concrete pouring at dosages of 1%–2% by cement weight. It also serves as a desiccant in gas drying units and as a raw material in chemical synthesis. For storage, keep bags sealed in a dry environment with relative humidity below 50%.
