The invention relates to pipe water treatment equipment. A connecting box is mounted at the upper part of a high-magnetic-conductivity core device in a sleeving manner, an insulating box communicates with the upper part of the connecting box, and a circuit board is mounted in the insulating box; a primary winding group and a secondary winding group are arranged in the connecting box, the primary winding group is connected with the circuit board, and the secondary winding group is connected with the high-magnetic-conductivity core device; the high-magnetic-conductivity core device comprises three or more groups of terminals with adjustable sizes and shapes, and the terminals penetrate hollow areas of the primary winding group and the secondary winding group; the high-magnetic-conductivity core device surrounds a pipe. The pipe water treatment equipment has the beneficial effects as follows: environmental pollution can be reduced, the equipment is high in adaptability, applicable to various fluids such as water and the like, applicable to static and flowing liquids as well as metal and non-metal pipes and simple to mount, pipe cutting and welding are not needed, and shutdown is not needed. The pipe water treatment equipment has good scale prevention and removal effects and has the functions of inhibiting growth of algae or bacteria in fresh water or seawater and inhibiting corrosion of iron-containing metal water pipes.
