Conduit connection with non-wetted strain sensor |
摘要 |
Apparatus and method for mechanically attached connections of conduits may include a conduit gripping member, a drive member, and a seal member, the drive member causing axial movement of the conduit gripping member to indent into an outer surface of the conduit when the assembly is pulled-up, the drive member causing the seal member to form a zero clearance seal at a location that is axially spaced from the conduit gripping member. The zero clearance seal may comprise a face seal arrangement including a gasket, and the conduit gripping member may be a ferrule, ring or other device that can grip and optionally seal against the conduit outer surface. The assembly may include a sensing function for detecting or sensing a characteristic or condition of an assembly component or the fluid or both. In one embodiment, a body coupling member has a two piece construction of a main body and a conduit socket insert. A flared fitting embodiment is also provided. Sensing functions are also incorporated into fittings other than just zero clearance fittings. |

1. A fitting for a fluid conduit having a longitudinal axis to make a mechanically attached flareless end connection therewith, comprising: a first coupling member and a second coupling member that are joined together when the fitting is pulled-up, a front ferrule and a back ferrule that are axially driven together by said first coupling member and said second coupling member to provide conduit grip and seal after the fitting is pulled-up, said first coupling member comprising a threaded nut and said second coupling member comprising a threaded body, said threaded body comprising a threaded portion, an end portion, and a neck portion between said threaded portion and a shoulder of said end portion, and a non-wetted strain sensor that is attached to said neck portion. |
