Product Description
Zirconium Welded Piping has strong affinity. They react with oxygen, hydrogen and nitrogen at about 200, 300 and 400 ℃ respectively. The reaction is rapid at higher temperature. Therefore, the melting and heat treatment should be carried out in vacuum furnace. When heat processing is carried out in the atmosphere, proper protection measures shall be taken and the operation time under high temperature shall be shortened.

Zirconium Welded Piping PHYSICAL PROPERTIES
Zirconium Corrosion Resistance
Zirconium Welded Pipe is very often specified for highly-corrosive industrial applications and frequently used in processes in which chlorides are a component. These and other very corrosive chemicals are damaging to lesser materials. This corrosion can rapidly lead to repair and/or replacement of the equipment in short time frame, causing expensive and highly disruptive process stoppage.
PARAMETERS (NOMINAL)
Executive standard: ASME SB658 / ASTM b658-07
Zirconium Alloy Pipe outer diameter 6.0-114mm
Zirconium Alloy Pipe wall thickness 0.3-8.0 mm
Zirconium Alloy Pipe length ≤ 18000mm
Zirconium alloys are solid solutions of zirconium or other metals, a common subgroup having the trade mark Zircaloy. Zirconium has very low absorption cross-section of thermal neutrons, high hardness, ductility and corrosion resistance. One of the main uses of zirconium alloys is in nuclear technology, as cladding of fuel rods in nuclear reactors, especially water reactors. A typical composition of nuclear-grade zirconium alloys is more than 95 weight percent zirconium and less than 2% of tin, niobium, iron, chromium, nickel and other metals, which are added to improve mechanical properties and corrosion resistance.
