ASTM B658M Zirconium 705 Pipe For Chemical And Water Cooled Reactors Application
Zirconium Zr705 Pipe ASTM B658M For Chemical And Water-Cooled Reactors Application
Zirconium Zr705 Pipe is a kind of metal with strong corrosion resistance, which is suitable for chemical corrosion-resistant equipment. Its acid resistance is better than that of titanium and various steels, and close to that of tantalum. Zirconium is also quite stable in alkali solution.
It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, serpentine heat exchanger, condenser, evaporator and pipeline.

Type
Zr702 and zr705 should be ASTM numbers. The only difference in composition is that the oxygen content of zr705 is a little higher, Zr702 is less than 0.16, and zr705 is less than 0.18. However, the mechanical properties of zr705 are better than that of Zr702. There is not much difference in corrosion resistance
PACKAGING
Zirconium Zr705 pipe is clearly tagged and labeled externally to make sure efficient identification and quality control. Great care is taken to avoid any damages which may be caused during transportation.
