Eneroil's Hinged Welded Rigid Centralizer or also known as Positive Bow Centralizers are uniquely designed with a flat-bottom U-profile of different depths, which permit an extremely high fluid passage. The straight bows provide nearly 100% stand-off (concentricity) when running inside a deviated cased hole. These premium-quality bows are strongly welded to the end collars and are made of a special alloy steel with uniform hardness providing optimum performance.
