Product Description
Zirconium Tube and Zirconium Pipe are made of metal zirconium and
other metals. Due to the excellent nuclear performance and
corrosion resistance of zirconium, zirconium alloy tubes and pipes
are often used in nuclear fuel assemblies and internal structures
of water-cooled reactors and are important nuclear materials.
At Superior Tube we commonly use zirconium-based alloys to
manufacture nuclear reactor components such as control rods and
cladding, coolant channels, seal tubes and other equipment intended
for use in a radioactive environment.
Zirconium alloys have low neutron absorption, high strength and
high corrosion resistance under different operating conditions.
Compared to stainless steels, zirconium tubing is desirable because
of its texture. The metal has a high yield strength and is more
resistant to irradiation creep and stress corrosion cracking.
Superior Tube can manufacture precision tubes in the following
