Advantages and Uses of Zirconium Heat Exchange Tube:
Zirconium is an important special material in acetic acid
equipment. Zirconium has better corrosion resistance and mechanical
properties than stainless steel, nickel-based alloys and titanium.
It is very suitable for manufacturing chemical equipment such as
containers, heat exchangers and instruments. Zirconium material has
properties such as corrosion resistance, extremely high melting
point, ultra-high hardness and strength. It is widely used in
aerospace, military industry, nuclear reaction, atomic energy,
chemical industry, petroleum, medicine and other fields.The grades
of zirconium materials currently produced include ZrR60702 and
ZrR60705. Generally, zirconium 702 is used. When high strength is
required, zirconium 705 can be used.
