Hinged Welded Bow Spring Centralizer
(COT-002)
The Crimson–Hinged Welded Bow Spring Centralizer is designed with very low starting and running force while giving substantial restoring force. These centralizers are designed to exceed the performance requirements of API Specification 10D for both starting and restoring forces. High-quality Bows made of special alloy steel with uniform hardness provide optimum performance.
The bows with extended profiles prevent them from hitting against casing collars. The centralizers have spring Bows strongly welded onto the outside of the end collars under the required temperature and condition with the correct grade electrode. Design and processing features for hinges hinge pins, and bow springs are similar to non-weld bow spring centralizers. Centralizers undergo a special process of rust prevention before powder coating.
