Seamless Copper Tube ASTM B280

ASTM B280 specifies the requirements for seamless copper tubes used in air conditioning and refrigeration applications. The primary materials covered under this standard include C12200, C10200, and C12000 copper alloys, each with unique properties suitable for various applications.

Description

ASTM B280 C12200 C10200 C12000 Seamless Copper Tube

Material

ASTM B280 specifies the requirements for seamless copper tubes used in air conditioning and refrigeration applications. The primary materials covered under this standard include:

  • C12200: Oxygen-free copper with high electrical conductivity.
  • C10200: High-purity copper with excellent corrosion resistance.
  • C12000: Copper with a slightly lower purity than C10200, but still suitable for various applications.

Specification

The ASTM B280 standard outlines the specifications for seamless copper tubes, including dimensions, tolerances, and mechanical properties. The tubes are typically used in HVAC systems, refrigeration, and other applications requiring reliable thermal and electrical conductivity.

Key Features

  • High Thermal Conductivity: Excellent heat transfer properties.
  • Corrosion Resistance: Suitable for various environmental conditions.
  • Formability: Easy to fabricate and install.
  • Non-Toxic: Safe for use in potable water systems.

Steel Grade

While the primary focus is on copper grades, it is essential to note that seamless copper tubes can sometimes be compared with steel grades in terms of applications. However, copper’s unique properties often make it the preferred choice for specific applications.

Application

Seamless copper tubes are widely used in various applications, including:

  • Air Conditioning Systems: For refrigerant lines.
  • Refrigeration: In commercial and residential units.
  • Plumbing: For water supply lines.
  • Electrical Wiring: Due to high conductivity.

Possible Alternative Grades

In addition to C12200, C10200, and C12000, other copper alloys may serve as alternatives depending on specific requirements:

  • C11000: Electrolytic tough pitch copper.
  • C14500: Copper with improved corrosion resistance.
  • C70600: Copper-nickel alloy for marine applications.
