Product Description

Zr702 Zirconium Welded Piping UNS R60702 For Coil-Heat Exchanger Applications

Zirconium Welded Piping is an alloy tube material made of zirconium and other metals. Due to its excellent nuclear and corrosion resistance, zirconium alloy tubes are often used in nuclear fuel assemblies and water-cooled reactor core structures. Pure zirconium tube is mainly used for manufacturing chemical equipment.

Zirconium Welded Piping NOMINAL SPEC

  • Executive standard: ASTM B523 / B523M-18, ASME SB-523, ASTM B658 / B658M-11, ASME SB-658 / SB-658M
  • Outer diameter: 6.0-114mm
  • Wall thickness: 0.3-8.0 mm
  • Length: ≤8000mm


The friction coefficient between zirconium and mould is high, and it is easy to adhere to the surface of the mold; The thermal effect of plastic deformation is remarkable, and good lubrication conditions are required during processing.


The processing specification has a sensitive influence on the performance of the product. In particular, the cold processing and heat treatment process before the finished product should be controlled to meet the requirements of use.
