Abstract: The assembly is composed of a framework having a longitudinal passage for receipt of a pipe to be wrapped and a number of crawler wheels which contact the outer wall of the pipe and which cause the framework to move longitudinally relative to the pipe. The assembly also includes brushes and wrapping assemblies mounted to rings which circumscribe the pipe. Rotation of the rings causes the brushes to scour the pipe outer wall and tape to unwind from the wrapping assembly onto the pipe. Hydraulic motors are provided on the assembly for powering the crawler wheels, brushes and wrapping assemblies. The hydraulic motors are activated by hydraulic fluid pressurized by pumps located remote from the assembly.
