ABSTRACT:
The apparatus (12, 112) includes a preferred number of permanent magnet units (14, 114) held against the exterior of a pipe (10, 110) through which liquid flows. Each unit (14, 114) includes permanent magnet means (20, 120) and a housing (22, 122) which encloses and tightly holds the permanent magnet means (20, 120) with no loose components and without the use of a potting compound, with the permanent magnet means (20, 120) being accessible through slots (23) provide in the housing (22, 122). The housing (22, 122) is formed from a flat sheet and includes a bottom panel (24, 124), side panels (26, 126), inwardly extending top panels (28, 128), and end panels (32, 132). The bottom panel (24, 124) abuts with the bottom of the permanent magnet means (20, 120), the side panels (26, 126) are bent to abut with the sides of the permanent magnet means (20, 120), the end panels (32, 132) are bent to abut with the ends of the permanent magnet means (20, 120), and the top panels (28, 128) are bent to abut with the top of the permanent magnet means (20, 120). In one of the preferred embodiments, an elongated tie strap (160) is sandwiched between the permanent magnet means (120) and the housing (122) within a depression (164) formed in the bottom panel (124) and the side panels (126).
