Apparatus and related method for coupling adjacent pipe lengths, for example, a drop pipe assembly that utilize an intermediate coupling member to prevent rotational disengagement of adjacent pipe lengths under the influence of rotational torque. The coupling member can comprise an internal key feature that physically engages a keyed end on at least one end of a length of pipe. The internal key feature can include key members located on each coupling end of the coupling member such that the key members engage corresponding keyed ends of adjacent lengths of pipe such that the coupling member prevents rotation of the adjacent pipe length relative to each other.

Anti-rotational pipe coupling

A utility conduit and related methods of assembling lengths of utility conduit with a mechanical spline connector. The utility conduit includes opposed male and female ends, wherein the male end is slidably insertable into the female end of adjacent conduits. The female end includes one or more circumferential sealing channels into which a seal member is positionable and an internal spline groove that is circumferentially defined inside the conduit. The female end includes a wall bore through a conduit wall that intersects with the internal spline groove. The male end includes an exterior spline groove on an exterior of the conduit. A spline can be inserted through the wall bore and into a space cooperatively defined by the internal spline groove and the external spline groove. The spline is inserted such that the spline occupies the space cooperatively defined by the internal spline groove and the external spline groove.
