The Bow Spring and Double Bow Spring centralizers are specially designed for vertical wells where low starting forces as well as high restoring forces are required. The Bows of these centralizers are heat treated in a special furnace which gives it the particular ‘bow spring’ action.

The specific hardness of the bows is calculated to ensure its performance exceeds the API 10D standards. Balancing the Starting Forces with the Restoring Forces taking care of the Running Forces makes it the ideal product for today’s severe down hole drilling conditions.

The flexing of the bows is a critical factor for these centralizers and the bows undergo a special state of flexing before assembly to ensure that they do not snap off under extreme stress conditions.

The following table shows the types of Bow Spring Centralizer that we provided.
