Zr-4 Tube / Zr-4 Bar

Production of Zr-4 Tube and Zr-4 Bar

To obtain the desired surface quality, cold rolling process is usually used in the production of Zr-4 Tubes rather than drawing process.
For cladding tube of the nuclear fuel elements, due to the high consumption and strict standard, two-roll or multi-roll cold rolling are usually used.

The size range of Zirconium alloy cladding tube for PWR is φ6 ~ 15mm × wall thickness 0.4 ~ 0.7mm. Zr-4 Rods for fuel element end plugs are normally produced through extruding the rods and forging them by cold rotation instead of cold drawing process.
