Home > Zirconium 702 Tube Fittings
Curtis Tube Fittings, Manila, Philippines is a well-known manufacturer of high-quality tube fittings for aerospace, chemical processing, marine, and energy industries. The company specializes in precision-engineered products and durable tube fittings that are built to international standards and deliver high performance in hostile environments. Zirconium 702 tube fittings, which are produced from commercially pure zirconium (Grade 702), exhibit superior corrosion resistance, particularly in aggressive chemical conditions. Available in several forms such as elbows, tees, and reducers, these fittings are well suited for use in nuclear power, marine, and chemical applications because of their heat resistance, strength, and high mechanical properties.
Zirconium 702 tube fittings contain 99.2% zirconium, with minor concentrations of hafnium (up to 4.5%), and trace impurities such as iron, nitrogen, and carbon. They have very good mechanical properties, with tensile strength of about 55,000 psi (379 MPa), yield strength of 30,000 psi (207 MPa), and elongation of 16%. Their physical characteristics are a density of 6.51 g/cm³, melting point of 1852°C (3366°F), and excellent corrosion resistance, which makes them suitable for applications in hostile environments such as chemical processing and nuclear industries.
