High temperature. Used to make heat transfer equipment (such as condenser, etc.).
It is also used in oxygen - making equipment to assemble cryogenic piping. Small diameter copper tubes are often used to transport pressurized liquids (such as lubricating systems, oil pressure systems, etc.) and pressure gauges for instrumentation.
The copper tube has a strong and corrosion-resistant property, and it is the first choice for modern contractors to install the plumbing, heating and cooling pipes in all residential commercial buildings.
