A pipe cleaning apparatus adaptor assembley (1A) consists of an adaptor (2) arranged to be connected adjacent an opening (101) of a pipe (100) to be cleaned and a flange head plate (12) to close the opening (101) of the pipe (100). The flange head plate (12) has at least one opening (19) therein. The flange head plate (12) is releasably retained with the adaptor (2) by pins (7) received in apertures (13). The opening (19) of the flange head plate (12) is able to receive a supply of compressed air which is able to travel through the opening (101) of the pipe (100) and into the pipe (100). The flange head plate (12) is removable from the adaptor (2) so that, in use, a cleaning pellet (70) is insertable into the opening (101) of the pipe (100) and then the flange head plate (12) can be returned to close the opening (101) of the pipe (100) and again be retained with the adaptor (2). A cleaning apparatus (1) consisting of the pipe cleaning apparatus adaptor assembly (1A) and a pellet launcher (40) is also described. Air is discharged into the pipe (100) by the pellet launcher (40) via the opening (19) in the flange head plate (12).
