Definitions

  • the invention relates to a method for the treatment of hard-drawn Pipes made of copper or a copper alloy for use in the sanitary area.
  • a multi-stage cleaning process where the inside of the pipe first with steam degreased, dried, treated with an abrasive and then blow with medically clean air becomes.
  • Another type of treatment is that Perform annealing in a reducing atmosphere and the resulting carbon film to be removed by an abrasive.
  • an abrasive either by pressurized water or compressed air.
  • the invention lies based on the state of the art the task is based on a method for the treatment of hard drawn copper or copper pipes to create a copper alloy for use in the sanitary area in which the Formation of carbon and / or oxide films in the Brazing or hot bending prevented and thus the pitting resistance of this Pipes is improved.
  • the method according to the teaching of the invention differs from the previously known in relevant soft annealed copper pipes Process by a combination of chemical and mechanical treatment stages.
  • the process succeeds in a surprising way Way, the formation of harmful films, e.g. B. carbon-containing pastures or oxide films, on the inner surface of hard-drawn Avoid copper pipes.
  • films acting as bipolar electrodes are formed usually in the case of brazing or Hot bending of copper pipes usual temperatures.
  • the invention is based on Embodiments explained in more detail.
  • tubes measuring 22 x 1 mm were used.
  • the tubes were treated with corundum for 10 s.
  • the mean roughness value R a was 1.0 am after the blasting agent treatment.
  • the residual carbon or lubricant content was again below the detection limit.
