ASTM B658 Zirconium Pipeline UNS R60702 For Industrial Corrosive Fluid Systems

Zirconium Pipeline is a highly corrosion-resistant metal, suitable for chemical-resistant equipment. Its acid resistance is better than titanium and various steels, and is similar to tantalum. Zirconium is also very stable in alkaline solutions.

The zirconium pipeline is made of metal zirconium and other metals. Because zirconium has excellent nuclear properties and corrosion resistance, zirconium alloy tubes are often used in the internal structure of nuclear fuel assemblies and water-cooled reactors. Pure zirconium pipes are mainly used to manufacture chemical equipment.

Zirconium Corrosion Resistance

Zirconium tubes are commonly used in highly corrosive industrial applications and are often used in processes where chloride is a component. These and other highly corrosive chemicals can cause damage to smaller materials. This corrosion can quickly lead to repair and/or replacement of equipment in a short period of time, leading to costly and highly destructive process interruptions.
