  • Air Conditioning Copper Tube AC Copper Pipe

    Air Conditioning Copper Tube AC Copper Pipe

    Air Conditioning Copper Tube AC Copper Pipes are core conductive components of air conditioning refrigeration systems. They are primarily used to connect indoor and outdoor units and transport refrigerant, while also handling heat exchange.

    1. Common diameters for Air Conditioning Copper Tube AC Copper Pipe: Φ6.35mm, Φ9.52mm, Φ12.7mm, etc. Gas pipes (low pressure) are typically thicker than liquid pipes (high pressure).

    2. Standard copper pipes: Wall thickness 0.5~0.7mm, suitable for low-pressure refrigerants such as R22.

    3. Degreased copper pipes: Wall thickness 0.8~1.0mm, degreased and thicker, specifically designed for high-pressure refrigerants such as R410A and R32, offering enhanced pressure resistance and explosion-proof performance.

  • Copper Tube Pipe

    Copper Tube Pipe

    Copper tube pipes are seamless tubing made of pure copper or copper alloys. They are strong, durable, and have good thermal conductivity.

    Classification of Copper Tube Pipes:

    1. By Material: Common copper tube pipes include pure copper, brass, bronze, and cupronickel. Further subdivisions include oxygen-free copper and phosphorus-deoxidized copper.

    2. By Shape: Copper tube pipes are divided into round, square, and rectangular tubes, as well as various irregularly shaped tubes manufactured according to drawings.

    3. By Application: Including air conditioning copper pipes, condenser pipes, electrical conduits, water pipes, and industrial pipes.

    4. By Manufacturing Process: There are drawn tubes, extruded tubes, and welded tubes. Based on hardness, they are divided into soft copper tubes and hard copper tubes.

  • Hollow Brass Tube Pipes

    Hollow Brass Tube

    Hollow brass tubes are seamless metal tubes made primarily of copper-zinc alloy.

    1. Ordinary Hollow Brass Tubes: Composed only of copper (Cu) and zinc (Zn). Common grades include H96, H90, H80, H70, H68, H65, and H62.

    2. Special Hollow Brass Tubes (Special Brasses): Based on copper and zinc, elements such as lead, tin, manganese, nickel, and aluminum are added to enhance specific properties.

    – Lead brass (e.g., HPb59-1): Excellent machinability, commonly used in instrument components.

    – Tin brass (e.g., HSn70-1, HSn62-1): Strong resistance to seawater corrosion, specifically used in marine condensers and heat exchangers.

    – Other: Brass tubes containing manganese, iron, silicon, etc., are used in high-strength or special corrosion-resistant applications.
