Carbon Steel Copper Coated Bundy Tube Double Walled Low Carbon Steel Tube

Bundy tube sometimes called bundy pipe, is type of double-walled low carbon steel tube manufactured by rolling a copper coated steel strip through 720 degrees and resistance brazing the overlapped seam in a process called budywelding.Bundy Tube, originally called the double wall low carbon steel tube, is now used to refer to high precision single wall low carbon steel tube in many areas, because many of the application and post-processing of the tubes are very similar.

Bundy Tube

Bundy tube covers single-wall, double-wall, copper-brazed steel tubing, zinc-coated steel tubing suitable for general engineering uses, particularly in the automotive, refrigeration, and stove industries for fuel lines, brake lines, oil lines, heating and cooling units, and the like. The tubing is available in either of two types, single strip or double strip. It is delivered in straight length or coil type.

• Construction:

  • Bundy tubing is made of double-walled steel, where two strips of steel are brazed or welded together.
  • This process involves forming the strips into a tube, overlapping the edges, and brazing them to create a leak-proof seam.

• Materials:

  • The steel is often coated with materials like copper or zinc to provide corrosion resistance, depending on the application.

Size and Tolerance

Limitations:

• Heavier than some alternative materials (e.g., aluminum or plastic tubing).
• Requires proper coatings to ensure long-term corrosion resistance in certain environments.

Advantages:

• High resistance to pressure and mechanical stress.
• Good corrosion resistance when coated appropriately.
• Cost-effective compared to other high-pressure tubing materials.

Applications:

• Automotive: Commonly used in brake and fuel lines because of its ability to withstand high pressures and harsh environmental conditions.
• Refrigeration: Found in condenser and evaporator coils for transferring refrigerants.
• Hydraulics: Used for carrying pressurized fluids in machinery and equipment.
