UNS R60702 Seamless Zirconium Tubing Zr702 Heat Exchanger Applications
UNS R60702 Zirconium Seamless Tubing Zr702 For Heat Exchanger Applications
Zirconium Seamless Tubing is a type of metal with strong corrosion resistance, which is suitable for equipment with chemical corrosion resistance. Its acid resistance is better than that of titanium and other steels, and similar to that of tantalum. Zirconium is also stable in alkaline solution. It is widely used in tube heat exchanger, coil-heat exchanger, serpentine tube heat exchanger, condenser, evaporator, pipe and other heat exchange equipment.
