Welding
Tank Lorry made with Titanium

Applications

Transportation of sodium hypochlorite

Although titanium has excellent corrosion resistance, it is commonly used as a tank lorry, which is difficult to use for hydrochloric acid and caustic soda, and for sodium hypochlorite (partially chromic acid).
The tank material that can transport sodium hypochlorite other than titanium,
1) made with Teflon lining
2) made with FRP + PVC
There are many customers who change to titanium due to concerns about contamination caused by peeling of resin materials and maintenance problems.
