Which friend has the national standard about seamless copper tube and aluminium tube, some help to send, very grateful, urgent!
National standard for seamless aluminium tubesnominal outside diameterOrdinary (+)High precision (+)Any outside diameter a and nominalAllowable deviation of outside diameterAllowable deviation of average outside diameter B and nominal outer diameterAny outside diameter a and nominalAllowable deviation of outside diameterAllowable deviation of average outside diameter B and nominal outer diameterAnnealing tube5083 CQuenchOtherAll tubesAnnealing tubeQuench tubeOtherAll tubes> 120 to 150Two point two eightZero point six threeZero point seven sevenZero point three eightZero point three eightOne point five zeroZero point five zeroZero point two fiveZero point two five> 150 to 180Three point four fourZero point nine fiveOne point one fourZero point five sevenZero point five sevenTwo point two fiveZero point seven sixZero point three eightZero point three eight> 180 to 220Four point five eightOne point two fiveOne point five threeZero point seven sevenZero point seven sevenThreeOneZero point five zeroZero point five zeroA any outer diameter refers to the outside diameter measured at the point at the pipe section.The mean od of B refers to the average value obtained by measuring the total diameter of two arbitrary angles at the cross section of the pipe.When the C 5083 alloy tube is annealed, the deviation is performed by the annealing tube.[amendment to the national standard 2012-06-14 14:45] seamless copper tube
