A pipe wall casting for installation in a poured concrete tank wall. The length of the wall casting is equal to the wall thickness, and the ends of the wall casting are grooved or shouldered for use with standard split-clamp couplings. A radially spaced annular shroud surrounds each end of the connector to provide an access well having clearance for installing or removing a split-clamp coupling. An integral water-stop flange around the outside of the shroud has outwardly extending tabs provided with rigging holes for mounting the wall casting on a free-standing support structure independently of the formwork for the concrete wall.
