1. Introduction to ASME SB-210 Standard
ASME SB-210 is a technical specification standard for aluminum and aluminum alloy seamless tubes established by the American Society of Mechanical Engineers (ASME). This standard comprehensively regulates the material composition, mechanical properties, dimensional tolerances, and other technical requirements for aluminum seamless tubes, ensuring their quality and performance in industrial applications.
- Scope of Application: Covers seamless aluminum tubes for industrial use
- Technical Requirements: Includes chemical composition control, mechanical performance indicators (tensile strength, yield strength, elongation, etc.), and dimensional tolerances
- Manufacturing Processes: Encompasses key production stages such as smelting, rolling, and heat treatment
2. Material Characteristics of Alloy 1060 Aluminum
Alloy 1060 is a high-purity industrial pure aluminum renowned for its excellent electrical conductivity and ductility.
Aluminum finned tubes are heat exchange elements that enhance heat transfer efficiency by attaching aluminum fins to the surface of the tube to increase the heat transfer area. They are typically made by joining aluminum fins to a base tube (such as steel, copper, or stainless steel) through welding, rolling, or mechanical bonding. They utilize the high thermal conductivity and lightweight properties of aluminum to improve overall heat transfer performance.
