ABSTRACT:
A method of forming a cuff on a section of tubular pipe which defines first and second ends and inner and outer surfaces. The method comprises the initial step of applying an outer layer of polymer material to a portion of the outer surface of the pipe such that a portion of the outer layer extends beyond and covers the first end of the pipe. Thereafter, an inner layer of polymer material is applied to a portion of the inner surface of the pipe. The inner layer is then blended into the outer layer so as to define a bull nose of the cuff which extends beyond the first end of the pipe.
