ASTM B234 is a standard specification for aluminum and aluminum alloy drawn seamless tubing for condensers and heat exchangers, and the following is a detailed interpretation of the standard: 1. Overview of the standard Standard number: ASTM B234 Scope of application: This standard applies to aluminium and aluminium alloy drawn seamless tubes used in condensers and heat exchangers. It specifies the requirements for the chemical composition, mechanical properties, size, appearance quality, inspection and testing methods of these tubes, etc. Second, the main requirements Performance requirements: The pipe needs to meet certain mechanical property requirements such as tensile strength, yield strength, and elongation. These requirements are specified according to the type of alloy of the material, the drawing process and the state of heat treatment. Test methods: The standard specifies corresponding test methods to evaluate the mechanical properties of tubes, such as tensile tests, etc. Dimensions & Tolerances Size requirements: The standard stipulates the outer diameter, wall thickness, length and other size specifications of the pipe to ensure the interchangeability and consistency of the pipe. Tolerance range: According to the purpose and accuracy requirements of the tube, the corresponding tolerance range is given in the standard. Appearance quality Appearance requirements: The surface of the pipe should be smooth and clean, no cracks, no porosity, no inclusions and other defects. The color should be uniform and consistent, with no obvious color difference. Inspection Method: Evaluate the appearance quality of the tube by visual inspection, surface finish measurement, etc. Third, the field of application Aluminum and aluminum alloy drawn seamless pipes under the guidance of ASTM B234 standard are widely used in various fields such as: condenser heat exchanger Chemical, petroleum and other industries. IV. Conclusions In order to get the most up-to-date information on the ASTM B234 standard, it is recommended to visit ASTM International’s official website directly or purchase the standard file.
