Hinged Semi-Rigid Welded Bow Spring Centralizer
Oil Baron Supply’s s Hinged Welded Semi-Rigid Centralizers ensure high efficiency in a
variety of casing jobs. The advantage is that Welded Centralizers have more restoring
force when compared to Non-Welded Centralizers. Ultimate strength and uniformity is created by the double crested Bow Springs, which are welded to the End Collar under special temperature conditions using extra low hydrogen coated electrodes. Further stability is provided by the integral hinge that remains intact even when under stress.
The End Collars are also designed to give maximum toughness due to a reinforcing rib that is stamped into the End Collar. These Centralizers are available in a combination of Bows configured from a choice of four standard Bow heights for optimal starting and restoring force. All centralizers undergo a special iron phosphate coating process to protect against corrosion and are then coated with a special polyester powder.
The Centralizers generally shipped in half assembled condition to reduce shipping and
storage costs.
They are available in all sizes ranging from 3 1/2” to 20”.
Any special sizes or combination can be made available upon request.
