The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore， they are generally used in power plants， switches of electrical equipment， and places where the connection points are far away and do not need to be bent.

The length of the copper tube can be longer if the coil is used. If the connection point is longer， it can be cut randomly according to the length， so as to prevent leakage when welding the copper tube.
