The standard defines the dimensions and tolerances for these welded cold drawn steel tubes. These include: 1. Outer Diameter (OD): The outer diameter of the tube is measured from the outside edge to the opposite outside edge. The tolerances for OD are specified in the standard, and they depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the tolerance is +/- 0.08mm. For tubes with an OD between 30mm and 50mm, the tolerance is +/- 0.1mm. 2. Inner Diameter (ID): The inner diameter of the tube is measured from the inside edge to the opposite inside edge. The tolerances for ID are also specified in the standard and depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the tolerance is +/- 0.05mm. For tubes with an OD between 30mm and 50mm, the tolerance is +/- 0.07mm. 3. Wall Thickness: The wall thickness of the tube is measured as the distance between the inside and outside surfaces of the tube. The tolerances for wall thickness are specified in the standard and depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the tolerance is +/- 10% of the wall thickness. For tubes with an OD between 30mm and 50mm, the tolerance is +/- 8% of the wall thickness. 4. Ovality: The ovality of the tube is the difference between the maximum and minimum diameters of the tube divided by the nominal diameter. The tolerances for ovality are specified in the standard and depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the maximum ovality tolerance is 0.5% of the OD. For tubes with an OD between 30mm and 50mm, the maximum ovality tolerance is 0.6% of the OD. 5. Straightness: The straightness of the tube is measured as the maximum deviation from a straight line over a specified length. The tolerances for straightness are specified in the standard and depend on the size of the tube. For example, for tubes with an OD of up to 30mm, the maximum deviation tolerance is 0.3mm per meter. For tubes with an OD between 30mm and 50mm, the maximum deviation tolerance is 0.5mm per meter. 6. Length: The length of the tube is specified in the standard and can vary depending on the application. The standard specifies that the length tolerance for tubes up to 7 meters long is +/- 10mm. For tubes longer than 7 meters, the length tolerance is +/- 0.15% of the length.
