The application of copper tube The copper tube is generally used in the heat exchange equipment， and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids， and can also be used as pressure measuring tubes in instruments; In addition， the copper pipe is relatively firm， unlike other metals， so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.
