For producing controlled precipitation in fluid flowing through a pipe, a coil of electric wire, of flat, generally rectangular spiral shape, is sandwiched between flexible cover sheets. The resulting assembly is applied to the outer circumference of the pipe, with the lengthwise dimension of the coil extending perpendicularly to the flow inside the pipe. A time-varying electric current is applied to the coil to produce a corresponding magnetic field. This, in turn, causes induction which produces the controlled precipitation.

[ What is claimed is:] [1.] An apparatus for use in reducing scale formation inside a vessel having an outer surface and adapted to contain flowing fluids, said apparatus comprising:a coil formed from a length of wire having opposite ends, each end being adapted to be connected to an electrical source,said wire, when placed on a substantially flat surface forming concentric rectangles having long and short legs; andsaid coil being adapted to be applied and secured to said vessel so that said long legs of said coil are substantially perpendicular to the direction of the fluid flowing through the vessel.
