Product Description

UNS R60702 Zirconium Pipe Fitting ASME SB-658 For Heat Exchanger Application Zr702

Zirconium Pipe Fitting is an alloy tube material made of zirconium and other metals. Due to the excellent nuclear and corrosion resistance of zirconium, zirconium alloy tubes are often used in the nuclear fuel assemblies and in core structures of water-cooled reactors. Pure zirconium tube is mainly used to manufacture chemical equipment.

FEATURE OF Zirconium

(1) Zirconium and gas have strong affinity. They react with oxygen, hydrogen and nitrogen at about 200, 300 and 400 ℃ respectively. The reaction is rapid at higher temperature. Therefore, the melting and heat treatment should be carried out in vacuum furnace. When heat processing is carried out in the atmosphere, proper protection measures shall be taken and the operation time under high temperature shall be shortened.


(2) 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.


Zirconium Pipe Fitting Applications

Therefore, zirconium is mainly used in chemical equipment, especially in equipment with high corrosion resistance requirements. Zirconium is mainly used to make heat exchangers, vessel lining, valves, pump shells, blades, agitators, pipes, etc. in chemical equipment. Zirconium is used in many chemical equipment producing fertilizers, resins, plastics and acids.
