Abstract:
An insert bowl, bushing, or spider includes a bowl having a central bore defined by an inner surface having an upper tapered section for engaging slips supporting a work string and a lower section. A wear indicator, such as a groove or substantially horizontal groove, is formed in the inner surface of the bowl and provides a visual indicator of wear to the bowl. A second wear indicator, such as a groove or substantially horizontal groove, may also be formed in the inner surface of the bowl. The inability to visually detect all or a portion of the wear indicator signifies that maximum recommended wear to the bowl has been reached and the bowl should be replaced to avoid damage to the work string.
