Zirconium 705 tube is a rare metal with amazing corrosion resistance, extremely high melting point, super hardness and strength, and Zirconium 705 tube widely used in aerospace, nuclear reaction, and atomic energy fields.
Zirconium alloy pipe 's melting point is 1800 degrees, while that of titanium Around 1600 degrees. The melting point of zirconium dioxide is as high as 2700 degrees.
1. Zirconium grade; ZR60702 ZR60705
2. Zirconium standard; ASTM B658 GB/26283
3. OD:6.0-108mm; wall thickness (1.0-4.5mm); length (2000-6000mm)
4. Application: used in petroleum, chemical industry, salt making, pharmaceutical, metallurgy, electronics, aviation, aerospace, marine and other related fields.
5. Straightness: 3mm/M
6. Flaring test of zirconium tube:The Zr-1 zirconium tubes for heat exchange should be tested for flaring, using a tool with a top core taper of 60 degrees for flaring. When the expansion rate of the inner diameter of the sample is 15% after flaring, no cracks should appear at the end of the sample.
7. Ultrasonic testing of zirconium tubes:Pipes are to be inspected by ultrasonic flaw detection. The acceptance of standard flaw (U-shaped) size and flaw detection results shall comply with the relevant requirements of GB/T 12969.1.
8. Metallographic structure of zirconium tube:The average grain size of ZR1 pipes recrystallized and annealed for zirconium tubes should not be thicker than grade 7 in GB/T6394-2002.
