Industry standards impose strict regulations on the manufacturing of shaped aluminum capillary tubes, including material composition, dimensional tolerances, and surface finish. For example, ASTM B210 specifies the dimensional and shape tolerances for aluminum alloy tubes, while GB/T 4436-2012 sets requirements for the mechanical properties of domestic products. During production, dimensions must be monitored in real time using online testing equipment (such as laser diameter gauges) to ensure that each tube conforms to the standards.
