A topic that receives considerable discussion among arts and entertainment riggers will be discussed at LDI 2017. Carl Petersen, director of engineering, Nicopress, will present a technical session: Dissimilar Metals Considerations on Various Combinations of Compression Sleeve and Wire Rope Terminations and Splices.
When compression sleeves are used for terminating and connecting mechanical load bearing wire ropes, often the sleeve and cable materials selected are dissimilar metals. Once a cable and sleeve assembly is placed into service, there are natural physical and chemical interactions that may occur between the various dissimilar metals used in the assembly depending on the cable and connector materials used, and the environment to which they are exposed. Questions regarding the metals compatibility and interaction become important considerations, since certain combinations of materials and environment may subject the swaged termination to corrosion.
This presentation provides a brief theory on how dissimilar metals are defined; how corrosion occurs and how to minimize it; and, assistance in the proper selection of best compression sleeve material and plating choices for a given cable material and the environment to which the connector/cable assembly may be subjected.
The session, #C50, will be from 3:30 p.m. to 5:00 p.m., Sat., Nov. 18, Rm. N226. Attendees will be awarded 1.5 ETCP renewal credits. LDI attendees can pick up a copy of the technical bulletin at the Nicopress booth #1633.
