Zr702 Zirconium Welded Pipe UNS R60702 For Corrosive Fluid Pipeline Systems
Zr702 Zirconium Welded Pipe UNS R60702 for corrosive fluid pipeline systems
Zirconium welded pipe is made of metal zirconium and other metals. Due to the excellent nuclear performance and corrosion resistance of zirconium, zirconium alloy pipes are often used in the internal structure of nuclear fuel assemblies and water-cooled reactors. Pure zirconium pipe is mainly used for manufacturing various corrosive fluid transmission pipeline systems.

Zirconium Corrosion Resistance
Zirconium Welded 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.
PARAMETERS
- Zirconium pipe outer diameter 6.0-114mm
- Zirconium pipe wall thickness 0.3-8.0 mm
- Zirconium pipe length ≤ 18000mm
