Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 19850-2005 "conductive Seamless, round copper tubes." This standard compared with GB/T 19850-2005, the main
Technical changes as follows.
--- Standard name from "Seamless, round copper tubes conducting" to "conducting Seamless Copper Tube";
--- Increased TU0, TU1, TUAg0.1 grades;
--- Increased torque (square) and the corresponding provisions of brass;
--- Straight circular tube outer diameter capped by 159mm to 178mm; wall thickness is reduced by the upper limit of 25mm to 10mm; minimum length
Decreased from 1500mm to 900mm, capped by 7500mm to 8500mm;
--- Canceled the chemical composition, "for impurity elements not only for analysis, but should ensure";
--- Canceled circular tube diameter and wall thickness of ordinary level tolerance;
--- Improve the accuracy of the pipe length to allow deviation;
--- The non-annealed drawn by the circular tube roundness "of not more than 1.5% of the nominal diameter" as amended by the diameter to thickness profile given deviation score;
--- The "straight pipe, cut slope comply with GB/T 16866" finalization is not annealed drawn straight circular pipe nominal outside diameter of the press
Binning and length dimensions given deviation; improving the circular tube cut-gradient index;
--- Mechanical properties added Brinell or Vickers hardness selected as prescribed;
--- Increasing the hydrogen embrittlement test selected as prescribed;
--- Adjustment formulas pipe hydrostatic test pressure;
--- Number of sampling pipe pressure test and pressure test from 20% to extraction by the root;
--- Appendix A conversion table of resistivity and conductivity increased in volume resistivity and mass resistivity, conductivity between
Conversion.
