ABSTRACT:
A flange protector (P) is adapted for attachment to a machined surface (S) of a flange (F) of the type having an annular ridge (20) and a plurality of bolt holes (14), which bolt holes (14) extend from surface (S) through the flange. A cover (10) of flexible material has one side (10s) shaped substantially conforming to the shape of the machined surface (S) and extends over the bolt holes (14) to engage and protect the machined surface (S). A plurality of fastening means (M) extend from the engaging side (10s) of the cover (10) for frictionally engaging the interior surface (14i) of bolt holes (14) to retain the engaging side (10s) in engagement with surface (S). Each fastening means (M) includes an elongated tubular shank (12) extending from the cover (10) to an open end (12e). Each tubular shank (12) is hollow, having an inner bore (12b) substantially from the cover (10) to the open end (12 e). The length of tubular shank (12) is shorter than the length of the bolt holes (14) which extend through the flange to avoid inadvertent unseating of the protector.
