Piping Standard Dimensions

Standard Dimensions of Copper Tubes

For standard sizes of copper tubes of three types (type A, B and C), standard wall thickness along with standard weight per unit length of the tube is presented in the following tables. All dimensions are as per ASTM B88. The tube wall thickness and tolerance is given in mm. The tube mass per unit length is given in (kg/m).
