Zr702 Seamless Zirconium Tube UNS R60702 For Corrosive Fluid Pipeline Systems
Zr702 Zirconium Seamless Piping UNS R60702 For Corrosive Fluid Pipeline Systems
Zirconium Seamless Piping is a kind of metal with strong corrosion resistance, which is suitable for equipment with chemical corrosion resistance. Its acid resistance is better than that of titanium and other steels and close to that of tantalum. Zirconium is also stable in alkaline solution. General industrial zirconium is mainly used in chemical and electronic industry, mainly used in the corrosion resistance and conductivity of zirconium tube.

Zirconium Corrosion Resistance
Zirconium Seamless Piping is often specified for highly corrosive industrial applications and are often used in chloride based processes. These and other highly corrosive chemicals can damage smaller materials. This corrosion can lead to rapid repair and / or replacement of equipment in a short period of time, resulting in costly and highly destructive process stoppage.
