zirconium pipes & Tubes

Applications of Zirconium Tubes Nuclear Applications The best use of Zirconium alloys tubes is for structural material for nuclear reactors due to the low thermal neutron absorption. Because zirconium has a lower absorption of neutrons than most metals it is the material of choice to improve reactor efficiency. However, in this application the low hafnium grade should be used for reactors. The alloys most used are: Zr-702 and Zr-704, having excellent corrosion resistance to high steam temperatures and good yield stress. Chemical Processes Used for structural material in the chemical processing industry including excellent corrosion resistance in most organic and inorganic acids, chloride solutions and alkaline mediums.In certain applications it can extend its life beyond the rest of the plant’s life.Therefore, maintenance costs are low, and downtime is minimized. It is non-toxic and biocompatible. Used in heat exchangers, evaporators, tanks, packaging, reactors, pumps, valves and pipe. Heat exchangers, coolers and condensers Zirconium and zirconium alloy tube are increasingly used due to its cost effectiveness over other materials thanks to its longer life, low maintenance and downtime, and improved process efficiency. Due to its excellent heat transfer properties and durability Zirconium is replacing many graphite heat exchangers.Since zirconium alloys have an inherent corrosion resistance due to its inert oxide layer it can be used to great advantage in condensers. Piping Used in urea, acetic acid, formic, nitric, and methyl methacrylate production systems.Specificatons Zr 702 - UNS 60702 Zr 702 - ASTM B523 / ASME SB523 / DIN 2462 D3/T3 Zr 704 - UNS 60704 Zr 705 - UNS 60705 ASTM B551
