Eneroil’s Hinged Non Weld Rigid Centralizers are uniquely designed with a flat-bottom U-profile of different depths, which permit an extremely high fluid passage. These positive centralizers may be used for both casing and tubing applications that require concentric casing strings. The straight bows provide nearly 100% stand-off (concentricity) when running inside a deviated cased hole, while the self-locking design of the centralizer ensures a firm hold. Furthermore, the non-welded structure eliminates brittle spots and enhances durability.

Performance Features

  • Eneroil’s Hinged Non Welded Rigid Bow Centralizers are designed for centralising the casing pipe in vertical, deviated, and horizontal wells
  • High-quality steel alloy bows with flat bottom U-profiles of different depths permit an extremely high fluid passage.
