Chlor-alkali Industry
The chlor-alkali industry mainly produces important chemical raw materials such as sodium hydroxide, chlorine and hydrogen by electrolyzing saturated brine. Chlorine is extremely corrosive and places extremely stringent requirements on the corrosion resistance of equipment materials. Traditional metal materials will be quickly corroded in a chlorine environment, causing equipment damage. Titanium valves, with their excellent resistance to chlorine corrosion, have become an ideal choice for controlling the flow of chlorine in the chlor-alkali industry.
In the chlorine outlet pipeline system of the electrolytic cell, titanium valves are used to control the flow and pressure of chlorine and transport the chlorine produced by electrolysis to subsequent processing and manufacturing links. Due to the strong oxidizing and corrosive properties of chlorine, ordinary valves will quickly be corroded in a chlorine environment, resulting in problems such as sealing failure and pipeline perforation. The dense oxide film formed on the surface of the titanium valve can effectively prevent the contact between chlorine and the titanium matrix, thereby avoiding the occurrence of corrosion. This enables titanium valves to operate stably under conditions of high chlorine concentration and large temperature changes, ensuring the safety and continuity of chlorine delivery.
Titanium valves also play a key role in the drying, compression and storage of chlorine. In addition, titanium valves are also widely used in supporting equipment and auxiliary systems of the chlor-alkali industry, such as wastewater treatment and exhaust gas emission systems.
