Hinged Welded Bow Spring Centralizer (NE-B-02)

In this construction the bows of the Centralizers are welded onto the End Collars thus making it a Hinged Centralizer along with a Welded Construction.

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.
