Flexible Bow Centralizers

Bow-spring centralizers are made from a set of flexible springs attached to two collars. The flexible bows generate a restoring force that creates separation between the casing and wellbore.

Bow Spring Centralizers are designed and manufactured to assist casing running and cementing. Starting, running, and restoring force tests are performed to confirm that centralization products consistently exceed the requirements of API Specification 10D for centralizers.

  • Comply with API Spec 10 D for starting, running and restoring forces as tested in certified technical lab.
  • An adequate tested combination of steel grade with heat treatment results in a good relationship of hardness and flexibility to accomplish very good performance in casing running operations.
  • Thermal treatment on the blades optimize flexibility and hardness to guarantee good centralization of the casing with best restoring force of the blades during operation.
  • The Flexible Centralizers can be installed and located at any place along the casing utilizing either two stop collars, one stop collar installed inside the Centralizer or with one stop collar and against the casing coupling.

Well Secure Oil Tools Non Welded Bow Spring Centralizers are made under state of art Engineering Techniques and rugged quality system. They are developed to exceed API 10D specification for used under most demanding condition. These Centralizers are designed for High Restoring Force and Low Starting & Running Force for centralizing the casing pipe in Vertical, Horizontal and Deviated well.

Well Secure Oil Tools Welded  Bow Centralizers are high quality welded products, which meet or exceed API 10D specification. Welded Centralizer has more Restoring Force as compare to Non Welded Centralizer. The Centralizers have Bow Spring strongly welded to the End Collar under required temperature and condition with extra low Hydrogen coated Electrodes. Integral hinge folded on the inside stay intact even under extreme stress. The End Collars are designed with a Reinforcing Rib stamped into the End Collar to give maximum structural toughness.
