A cast-iron or steel pipe is coated with a two-component epoxy resin and then, prior to curing of the resin, is coated with a relatively thick layer of hydraulic concrete. A layer of a water-impervious bitumen is then applied over the concrete. The concrete layer does not extend over the spigot in a bell-and-spigot pipe, and a special fitting is provided for such a piece of pipe when the spigot end must be cut off.
