Abstract

Improvements introduced into a welded flanged ductile iron pipe, the pipe of which includes a flange member having an annular flange portion arranged around the end of the pipe and a generally cylindrical hub extending around and along the pipe from the innermost part in the radial direction of the flange part, the length (L) of the hub being related to the nominal internal diameter of the pipe (D) by the equation L = D l/n where n is a number between 1.10 and 1.60 and the units of length are in millimeters; the hub being welded around its free end to the outer wall of the pipe.
