2092089 9203384 PCTABS00010 The apparatus (12) includes a preferred number of permanent magnet units (14) held against the exterior of a pipe (10) through which liquid flows. Each unit (14) includes a permanent magnet pack (20) and pole pieces (16) at the ends of the magnet pack (20). A housing (22) encloses the permanent magnet pack (20), the pole pieces (16) projecting through slots (23) provided in the housing (22). The housing (22) includes a bottom panel (24), side panels (26), and inwardly extending top panels (28), each top panel (28) having an upwardly directed flange (30) thereon. Bolts (46) and nuts (48) pass through these upwardly extending flanges (30). Additionally, the housing (22) includes end panels (32) having outturned flanges (34). Wings (36) composed of reversely folded panels (38) have laterally spaced flanges (42) thereon. Additional bolts (50) and nuts (52) secure the flanges (34) on the end panels (32) to the flanges (42) on the wings (36) so as to maintain the wings (36) in an oppositely issuing relationship. Each wing (36) has a slot (40) formed therein so that any preferred number of units (14) can be held tightly against the pipe (10) through the agency of wires (54) threaded through the various slots (40). The number of units (14) to be employed depends upon the size of the pipe (10).
