The method includes the steps of cleaning, priming, and coating pipe segments with a bituminous composition. The coated pipe segments are wrapped and carefully handled so as not to disturb the bituminous coating. Wire reinforcing cages are formed around the pipe segments and the individual pipe segments are then loaded into individual mold cars positioned end-to-end upon a first railway track assembly. The cars are then translated onto a first transfer car, which rides on a second track means, and are conveyed to a third railway track assembly comprising a plurality of parallel sets of rails. The mold cars are transferred abreast from the transfer car onto the third railway track assembly, filled with a cementitious weight coating material and fed into a drying kiln whereby the cementitious weight coating cures at least until the cement becomes self-supporting. The cars are then translated abreast onto a second transfer car, riding upon a fourth track assembly, positioned at the other end of the third railway means. The molds are opened and the weight coated pipe segments are removed.

A diesel hammer (20) is adapted to produce uplift blows by connecting its casing (30) via a pulling connection (52) to a case (24) to be pulled, removing vent plugs (76) from the top of the casing, sealing all other openings (78), (82), (94), in the casing, applying compressed air from an external source (106) under the hammer ram (32) to drive it upwardly and thereafter allowing controlled flow of air out of the casing via a bleed line (118) and an adjustable orifice (238) to cushion the subsequent fall of the ram.

A method and apparatus for forming rings that is particularly suited for forming plow rings from elongated lengths of stock having irregular cross sectional shape. A length of stock (12) is positioned against a mandrel (20), the end of the stock being pre-bent from a previous bending operation, with the free end of the stock extending beyond the mandrel. A movable bending element (24) is brought into contact with the stock opposite the point of contact with the mandrel, and advanced around the mandrel partially bending the stock. A clamp (82) clamps the partially bent stock against the mandrel and a cutter (98) then cuts the stock, leaving a partial bend in the newly formed free end of the stock, the cut portion of stock being clamped to the mandrel. The length of stock is moved away from the mandrel so that the bending of the cut portion around the mandrel can be completed.
