Method for producing copper tubes |
| abstract |
Invention focuses on a method for producing copper tube and particularly fornhard-drawn temper sanitary tube. According to the method developed, thenextruded tube shell is cold formed until almost its final size, after which thentube undergoes inline annealing in oxidizing conditions in order to adjust thentube to its final size in the cold forming step with finally sand blasting to theninner surface of the tube. Through this method, the use of organic solventsnis avoided and at the same time a tube with excellent corrosion resistancenis achieved. |
