There are many types of copper pipes, and the common classifications are as follows:
According to the material composition
- Purple copper tube: such as TP2 purple copper tube, excellent thermal conductivity, commonly used in the field of high thermal conductivity requirements, such as refrigeration equipment evaporator, condenser, etc. .
- Brass officer: including H62, H65, H68 and other models, high strength, suitable for the manufacture of parts that require a certain degree of strength and corrosion resistance, such as valves, fittings and so on.
- Bronze tube: such as QSN6.5-0.1 tin bronze tube, good corrosion resistance, commonly used in chemical industry, marine and other fields .
- White copper pipe: Ni-Cu alloy, with good corrosion resistance and mechanical properties, in the field of desalination, chemical industry and other applications.
According to the production process
- Oxygen-free copper tube: high purity, very low oxygen content, suitable for the production of precision parts, such as electronic equipment in the connecting wire.
- Oxygen-containing copper tube: moderate strength and hardness, good weldability, mostly used as connection tube.
- Internal threaded copper tube: with threads on the inner wall, it can strengthen the heat transfer effect and is widely used in air-conditioning and other refrigeration equipment.
- Seamless copper tube: smooth internal and external surface, uniform wall thickness, seamless connection, good corrosion resistance, suitable for high pressure, high temperature and corrosion-resistant occasions.
- Welded copper tube: made by welding or brazing, lower cost, suitable for general use of the occasion.
According to hardness
- Soft state (O state) copper tube: soft, good plasticity and ductility, but low strength.
- Semi-hard state (1/2H) copper tube: moderate strength and plasticity, good processing performance, is the first choice for refrigeration piping.
- Hard state (H state) copper tube: high strength and hardness, but poor plasticity.
According to the use of points
- Water supply pipe: used in urban water supply network, building water supply system.
- HVAC pipes: used in central air conditioning system, heating system and ventilation system.
- Refrigeration pipe: used in refrigeration equipment and air-conditioning systems.
- Gas pipe: used in gas, natural gas and other gas piping systems.
- Electronic tube: mainly used for electronic equipment and instrumentation connection.
According to the shape
- Shaped copper tube: including square tube, octagonal tube, hexagonal tube, etc., which can be customized according to actual demand.
