<p>A pipeline joint protector (20) and (20a) which encircles the exposed end portions of abutting lengths of pipe which are wrapped or covered with concrete weight coating (c) substantially throughout their lengths with only short end sections (11a) and (12a) of the pipe exposed. The pipeline protector extends radially outwardly from the central pipe to approximately the diameter of the weight coat material and substantially spans the space between adjacent portions of weight coat material (c) on the abutting joints of pipe welded together to form the pipe joint. Alternatively, a pipe joint protector formed of a sheet of high density plastic material (30) wrapped around the pipe joints and overlaying the adjacent ends of the weight coat material on such pipe joint and as secured thereto.</p> |
