An interconnectable hollow metal pipe for the construction of force driven piles is described. A pipe connector is permanently secured to one of opposed open transverse ends of the hollow metal pipe for interconnecting like pipes together. The pipe connector has an inner fitment section for engagement in the one of opposed open end and a protruding pipe connecting section for tight sliding fit connection in the other hollow open end of another interconnectable hollow metal pipe. The pipe connector has securement formations which in combination with the pipe open end, to which it is connected to, forms at least two spaced-apart weld cavities with an outer surface of the pipe to receive therein a recessed weld which does not exceed the pipe outer surface to provide an unobstructed pile outer surface by two or more of the interconnectable hollow metal pipes interconnected end-to-end by the connectors.
