Fitting assembly evaluating apparatus and methods

摘要

The present application discloses methods and apparatus for installing fitting components, such as a conduit gripping device, on a conduit to form an assembly. The assembly is joinable with at least one other fitting component to form a fitting. The present application also discloses methods and apparatus for evaluating characteristics of components of a mechanically attached connection. Characteristics that may be evaluated include, but are not limited to, the position of a conduit gripping device on a conduit, an amount of axial compression or stroke of the conduit gripping device, an amount of clamping force applied to the conduit gripping device as the conduit gripping device is compressed, and an amount of torque applied to members that compresses the conduit gripping device.

主权项

1. A method of assembling a fitting comprising:
applying a predetermined torque between a first fitting component and a member to axially advance the first fitting component with respect to the member to pre-install a conduit gripping device onto a conduit with a first amount of compression so that the conduit gripping device grips the conduit; separating the first fitting component from the member; assembling the first fitting component with a second fitting component; applying said predetermined torque between the first fitting component and the second fitting component to axially advance the first fitting component with respect to the second fitting component with a second amount of compression so that the conduit gripping device grips and seals the conduit.
