Zr702 Zirconium Pipe Fittings UNS R60702 In Corrosive Fluid Pipeline ASTM B523

Zirconium Pipe Fittings are a kind of metal with strong corrosion resistance, which is suitable for chemical corrosion-resistant equipment. Its acid resistance is better than that of titanium and various steels, and close to that of tantalum. Zirconium is also quite stable in alkali solution.

It is widely used in heat exchange equipment, such as tubular heat exchanger, coil heat exchanger, serpentine heat exchanger, condenser, evaporator and pipeline.

Zirconium Corrosion Resistance

Zirconium 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.

Some of the common service applications of Zirconium Piping include:

• Acetic Acid
• Citric Acid
• Formic Acid
• Hydrochloric Acid
• Lactic Acid
• Nitric Acid
• Phosphoric Acid
• Sulfuric Acid

Zirconium and gas have 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
