Light weight, good thermal conductivity, high strength at low
temperature. It is often used in the manufacture of heat exchange
equipment (such as condensers, etc.). Copper coil pipe/tube also
used to assemble cryogenic pipelines in oxygen generating
equipment. Copper tubes with small diameters are often used to
transport pressurized liquids (such as lubrication systems, oil
pressure systems, etc.) and pressure measuring tubes used as
instruments.
Compared with ordinary plastic pipes, purple copper tubes can be
found that the main materials of plastic tubes contain chemical
additives such as plasticizer, which are easy to cause escape or
hardening and brittle of plastic due to changes in time and
temperature. The copper copper tube does not have various
modifiers, additives, additives and other chemical components of
the plastic tube, and its properties are very stable. Moreover, E.
Coli in the water cannot continue to breed in the copper pipe. More
than 99% of the bacteria in the water were completely killed after
entering the copper pipe for 5 hours. Moreover, the structure of
the copper tube is extremely dense and impermeable. Harmful
substances such as grease, bacteria, viruses, oxygen and
ultraviolet rays cannot pass through it and pollute water quality.
In addition, the copper tube does not contain chemical additives,
and will not burn and release toxic gases to suffocate people.
Moreover, the recycling of copper is beneficial to environmental
protection and is a sustainable green building material.
Classification
1. Pure copper coil pipe/ tube
It is mainly suitable for pipes and pipe fittings used in chemical
industry, HVAC, mechanical equipment, water supply system and other
industries.
2. Phosphorus deoxidized copper coil pipe/ tube
It is mainly suitable for pipes and pipe fittings used in air
conditioners, refrigerators, heat exchangers, refrigeration and
heating industries.
3. Oxygen-free copper coil pipe/ tube
It is mainly suitable for pipes and pipe fittings used in
industries such as power supply, communication and electronic
products.
