Materials: Zr702 (UNS R60702) zirconium
Zirconium (Zr): 99.2% minimum
Products: tanks, vessels, reactors, pipes, and heat exchangers.
Application: chlor alkali plants
Zirconium is widely used in the chlor alkali industry due to its excellent corrosion resistance to hydrochloric acid (HCl) and caustic soda (NaOH) solutions. These two chemicals are commonly used in the production of chlorine and other chemicals in the industry.
Zirconium is particularly well-suited for use in the chlor alkali process because it forms a protective oxide layer on its surface when exposed to HCl or NaOH, which prevents further corrosion. This oxide layer is stable over a wide range of temperatures and concentrations of the chemicals, making zirconium a reliable and durable material for use in equipment such as tanks, vessels, reactors, pipes, and heat exchangers.
Zr702, also known as UNS R60702, is a zirconium that is commonly used in the chemical processing industry due to its excellent corrosion resistance. Its composition is as follows:
The mechanical properties of Zr702 (UNS R60702) zirconium depend on the temper condition and can vary significantly. Below are the typical values for some common temper conditions:
Annealed (O):
Tensile strength: 345 MPa (50 ksi)
Yield strength: 140 MPa (20 ksi)
Elongation: 30%
Recrystallized (R):
Tensile strength: 415 MPa (60 ksi)
Yield strength: 205 MPa (30 ksi)
Elongation: 20%
Cold-worked (W):
Tensile strength: 585-725 MPa (85-105 ksi)
Yield strength: 345-515 MPa (50-75 ksi)
Elongation: 10-25%
Stress-relieved (M):
Tensile strength: 485-620 MPa (70-90 ksi)
Yield strength: 275-415 MPa (40-60 ksi)
Elongation: 15-25%
Note that these values are for reference only and actual properties may vary depending on the specific manufacturing process and testing conditions. It’s important to consult with us and follow appropriate industry standards and regulations when designing and using zirconium components.
In the chlor alkali industry, zirconium products are primarily used in the following areas:
Zirconium valves: Due to the excellent corrosion resistance of zirconium metal, it is used for manufacturing valves in the chlor alkali industry. Zirconium valves can withstand the corrosion of chlorine, caustic soda, hydrochloric acid, and other corrosive media, ensuring the safe and reliable operation of equipment.
Zirconium reactors and tanks: Chemical reactions are carried out in the production process of chloralkali, and zirconium reactors and tanks can withstand corrosive media such as caustic soda, chlorine gas, and hydrochloric acid under high temperature and high-pressure conditions.
Zirconium heat exchangers: Zirconium, with its excellent thermal conductivity and corrosion resistance, can be used in the manufacturing of heat exchangers in the chlor alkali industry. Heat exchangers facilitate the transfer of heat in chemical processes, improving energy efficiency.
Zirconium pipelines and fittings: Zirconium pipelines and fittings are used for transporting and connecting media in chlor alkali production, such as chlorine gas, caustic soda, and hydrochloric acid. Zirconium metal pipelines have strong corrosion resistance and high mechanical strength, ensuring the safe transport of media.
