| The Hinged Welded Standard Bow Centralizer is designed
to have a very low starting and running force while giving substantial restoring force.
These centralizers, as all other AOT products, are manufactured to full API Q1 and ISO
9001 specifications; although we do not advertise as carrying the API Monogram. API 10D
test have been run on several sizes for performance characteristics only. These
centralizers are typically maintained in stock in all popular hole sizes. Numerous
varieties are available, including Turbo Fins to aid in annulus turbulence and with integral set screws when running a stop
collar is not desired. The 500 Series Centralizer Line is developed to allow for the
widest variety of options which may arise in a casing running program.
