Abstract
Invention focuses on a method for producing copper tube and particularly for hard-drawn temper sanitary tube. According to the method developed, the extruded tube shell is cold formed until almost its final size, after which the tube undergoes inline annealing in oxidizing conditions in order to adjust the tube to its final size in the cold forming step with finally sand blasting to the inner surface of the tube. Through this method, the use of organic solvents is avoided and at the same time a tube with excellent corrosion resistance is achieved.
