ABSTRACT:
A method of forming lengths of pipe for assembly together to form fluid flow conduits includes the steps of providing a pipe having a first inner diameter and a central longitudinal axis, providing a ferrule which has an annular first end, having an inner diameter equal to the pipe inner diameter and having a second end formed into a flange adapted to form a flange coupling when abutted against and connected to another similar flange. The flanges have end faces countersunk approximately 1.degree. to 5.degree.. The first end of each ferrule is welded to an end of a pipe, whereby the end face of the flange assumes an orientation wherein the end face is substantially normal to the central longitudinal axis.
