Bow Spring Centralizers

‘NeOz’ NE-B Series Centralizers are specially designed for vertical wells wherein low starting forces as well as high restoring forces are required. The Bows of these Centralizers are heat treated in special furnace which gives it a peculiar ‘bow spring’ action.

The specific hardness of the bows calculated by our Engineers to make it performance exceed the API 10 D standards. Balancing the Starting Forces with the Restoring Forces taking care of the Running Forces makes it an apt product for today’s severe downhole drilling conditions. The flexing of bows is critical most factor for these Centralizers and the bows undergo special state of flexing before assembly to ensure that they do not snap off under extreme stress conditions.

NeOz has developed the following types of Bow Spring Centralizers for specific need of various drilling operators.

NeOz’s Non Weld Bow Spring Centralizers are specially designed for vertical wells wherein low starting forces as well as high restoring forces are required.The Bows of these Centralizers are heat treated in special furnace which gives it a peculiar ‘bow spring’ action.The Heat Treated bows enables these centralizer to provide best centralization as well as help in faster running of casing. The steel of these bows is a «special» made by combination or different metals to provide one of the best tensile strength as well as the «spring back» bow spring action.

In this type of Centralizers the End Collars have hinges which makes it in two halves.This enables them to be assembled at site.

The bows are locked to the End Collars via a special locking mechanism. These centralizers can be shipped in half thus reducing the freight cost.
