A method of cooling an outer wall of polymer pipe is provided. The method includes extruding a layer of polymer onto a pipe to form an outer wall of pipe; conveying the pipe including the outer wall of pipe through an inner aperture of an annular air-cooler having an annular air manifold; and blowing pressurized air, at a temperature lower than a temperature of the outer wall of pipe, through the annular air manifold such that it contacts the outer wall of pipe and cools the outer wall of pipe at a rate that is a function of a pressure of the pressurized air and a difference between the temperature of the pressurized air and the temperature of the outer wall of pipe. An apparatus for cooling an outer wall of polymer pipe is also provided.
