Method for manufacture of tubes of a zirconium-based alloy

摘要

Method for manufacturing tubes especially for fuel elements and tubes for construction of fuel rod skeletons made of zirconium-based alloy for nuclear reactors and a tube made thereby. The tubes are ground to a surface roughness of <=0.2 mumRa with a belt device of SiC-based belts, so-called "dressed" SiC-based belts with cotton back or SiC-cork belts. The tubes may possibly be polished after grinding with a wheel to a surface roughness <0.25 mumRa.
