Zusammenfassung:	The utility model discloses irregular strip steel used for pipe hoops for prestressed reinforced concrete well pipes. The utility model is characterized in that a channel, a lug boss and inclined planes are arranged on strip steel with certain thickness and width, wherein for example, in the picture, 1 and 4 are inclined planes, 2 is the channel with a right-angle trapezoid section, and 3 is the lug boss. When the utility model is used for making pipe hoops for well pipes, the utility model is cut, is bent into rings and is welded only. When the utility model is used as raw materials for making pipe hoops, the cutting process of channels and the welding process of lug bosses are saved, labor, time and raw materials are saved, and produced pipe hoops have high strength and better quality. The utility model is formed by rolling steel billets with certain shapes three times.
