ZR 702/ ZR 704/ ZR 705 Zirconium Alloy Tubes
Zirconium and zirconium alloy tubes are increasingly used because of their cost-effectiveness, long service life, short maintenance and downtime, and process efficiency compared to other materials.
Description
GNEE is able to produce zirconium tubes and zirconium alloy tubes. Zirconium alloys contain 95.5% to 99.2% zirconium and up to 4.5% hafnium. These alloys offer excellent corrosion resistance; Zr702 is commercially pure zirconium, and Zr705 is an alloy of zirconium and niobium for improved tensile and yield strength.
Products Description
The main features of Zirconium tubes are:
· High heat transfer efficiency
· Very low thermal expansion
· High resistance to erosion under tension
· High resistance to localized corrosion (pitting and crevice)
· Very good resistance in most organic acids
· Exceptional corrosion resistance in mineral acids
· Good corrosion resistance in strongly alkaline mediums
· Low thermal neutron absorption
