Product Description

Zirconium Welding Pipe And SeamlessPipe Zr 702 / Zr 705 Boiler and Pressure Vessel 

Zirconium Welding Pipe Zr702 ASTM B523 , ASTM B658, material Zr702 , Zr705 for aircraft, aerospace, chemical and heatexchanger high quality Zirconium Welding Pipe and seamless pipe.


Known as Zr702, the zirconium (UNS R60702) is a hafnium-containing commercial grade of zirconium which is widely used in industrial applications such as chemical processing equipment. Due to the exceptional corrosion resistance of zirconium to an extensive range of media, zirconium tubes (usually Zr702) are widely used for the construction of heat exchangers, coolers, condensers, heaters, piping and other boiler & pressure vessel equipment under harsh conditions. The annealed zirconium tubes shall be manufactured to ASTM B523/ ASME SB-523 in either seamless or welded type.
