The present invention relates to a pipe unit constituting a plastic greenhouse. More specifically, the pipe unit includes: a pipe which has both open ends and a pair of guides formed in the lengthwise direction thereon; a pair of planar heating elements inserted between the guides; a finishing part which is inserted into one end of the pipe and electrically connects one planar heating element with the other planar heating element; and a power connection part which is inserted into the other end of the pipe, electrically connects one planar heating element with the other planar heating element, and supplies power to the planar heating elements. The finishing part is inserted into one end of the pipe while the planar heating elements are installed in the pipe. When power is supplied to the power connection part while the power connection part is inserted into the other end of the pipe, power is supplied to one planar heating element, and then supplied power is supplied to the other planar heating element through the finishing part. One pipe can be connected with another pipe in an easy manner. The power connection part can be attached to and detached from the pipe. Therefore, locations of power connection can be arranged in an easy manner. |
