  • Conventional cleaning apparatus of this kind typically takes the form of a body arranged to fit within the pipe to be cleaned such that bristles or other cleaning formations depending outwardly from the body to contact the inner surface of the pipe. The frictional contact between the cleaning formations and the inside surface of the pipe cause cleaning or scouring of the pipe during passage of the body along the pipe in use.
  • a number of factors are known to influence the effectiveness of cleaning using a pig, such as, for example, the stiffness and length of the bristles; the degree of contact maintained between the bristles and inner surface of the pipe; and, the number or type or bristles arranged to pass over any given portion of the inner pipe surface.
  • a pig may have slight freedom of movement laterally within the pipe and may thus oscillate or jostle within the pipe as it passes therethrough with the result that opposing sides of the pipe may intermittently be cleaned to a greater or lesser degree.
  • a pig may also be urged into one side of a pipe as it passes around bend or curves in the pipe, resulting in greater friction with one half of the pipe wall and lesser friction with the opposing half.
