ABSTRACT:
A tubular branch pipe liner is proposed, which has a rigid collar at its end and to this collar is attached a protector consisting of a first portion which is out-spread downwardly and curved to fit on the lower face of the collar and is fixed thereto, a second portion which is roughly cylindrical and fitted into the inner peripheral face of the collar and the inner wall of a little part of the tubular branch pipe liner which is immediately continuous from the collar, and a third portion which extends downwardly and terminates in an annular end face at a location substantially lower than the joint where the first portion and the second portion meet; also proposed is a pipe lining method, which comprises the steps of preparing a branch pipe liner with a collar; and attaching the above-mentioned protective member to the collar; and lining a branch pipe with the tubular branch pipe liner; and lining the main pipe with a conventional main pipe liner; and cutting a hole through that circular portion of the main pipe liner which is defined by the annular end face of the third portion of the protective member.
