Hinged Welded Double Bow Spring Centralizer (NE-B-08)

Double Bow Spring Centralizers can be used in Deviated wells which require low running forces.  These are designed to pass through tight spots and doglegs. The Double Bow Design makes these Centralizers act as a rigid centralizers under high side loads. In this construction the double 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.

 

Hinged Welded Double Bow Centralizer c/w Integral Stop (NE-B-11)

 

This Centralizer is also available with Integral Stop option wherein Set Screws are available on the End Collars. In this case the stop collars requirement is eliminated however this Centralizer would not float on the casing.

Double Bow Spring Centralizers with Integral stop can be used in Deviated wells which require low running forces.  These are designed to pass through tight spots and doglegs.
