ASME SB523 Zirconium Alloy Tubes
Zirconium Alloy Tubes are completely resistant to alkali solution and molten alkali. The corrosion resistance of zirconium in sodium hydroxide medium is the same as that of nickel. Because zirconium has excellent corrosion resistance, it is much better than tantalum and precious metals in many cases. In addition, zirconium also has good mechanical properties and high temperature resistance.

Zirconium is a kind of metal with strong corrosion resistance, which is suitable for chemical corrosion-resistant equipment. Its acid resistance is better than that of titanium and various steels, and close to that of tantalum. Zirconium is also quite stable in alkali solution.
It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, serpentine heat exchanger, condenser, evaporator and pipeline.
Zirconium Corrosion Resistance
Zirconium pipe is very often specified for highly-corrosive industrial applications and frequently used in processes in which chlorides are a component. These and other very corrosive chemicals are damaging to lesser materials. This corrosion can rapidly lead to repair and/or replacement of the equipment in short time frame, causing expensive and highly disruptive process stoppage.
