�Conference: FSA Technical SymposiumPaper Title: "Evaluating Live Loading of Bolted Joints to Improve Gasket Performance Life"Nashville, Tennessee April 26Abstract:In this day and age, utilizing the most effective gasket sealing products is a must. In previous published papers it has been discussed that flange Live Loading has shown to be an effective method of enhancing a gasket's length in service. This paper will evaluate four different factors: belleville spring configuration, gasketmaterial, gasket thickness, & gasket stress levels. The testing protocol will be based on an accelerated thermal cycling steam test that includes intervals of extreme thermal shock to simulate a rapid cooling process. This testing will result in a comprehensive information matrix of overall gasketing performance with and without liveloading.

�Conference: ASME Pressure Vessels and Piping ConferenceTitle: Utilizing Direct Tension Squirter indicators in Industrial ApplicationsDenver, Colorado July 17thAbstract:�In the world of critical bolting applications there is a need for achieving correct gasket loads. The new technology of Direct Tension Squirter Washers is designed to show visual indication when 60% of yield for a B7 bolt has been reached. Torque wrench inconsistencies have caused many gasket failures. There are many times the incorrect gasket load has been applied to bolted joints resulting in joint failure. The root cause of these failures range from bad calculation of friction for anti seize to damaged threads. DTSW ensures the bolts have reached the correct bolting load resulting in a properly loaded gasket that will not be doomed for failure.�This paper will review the DTSW Technology and how it can be applied in Industry applications. It will discuss the inaccuracy of torque wrench technology in today’s industrial bolting environment. The paper will also highlight show the DTSW technology ease of use compared to typical Indicator washers that require feeler gauges.

�Conference: AOV Users Group 2006 MeetingPaper Title: "Nuclear Valve Packing Performance Testing"Clearwater, Florida January 14th�ABSTRACT�One of the most important challenges in today’s nuclear Valve arena is the balance between packing performance and its frictional footprint. We have undertaken a logical testing protocol to gather data on valve packing’s performance/friction values throughout a full steam thermal cycle. This testing will focus on different packing materials and designs. Also the research will focus on the relationship between the combined value of the packing coefficient of friction and the ratio of gland load forces. This data could perhaps assist the industry in determining a better model for valve friction calculations. Another facet of this testing will focus on live loading spring heights after a loss of gland load being re-tightened to the original heights for frictional concerns. Today it is important to utilize best available packing technology that can enhance AOV/MOV operability without sacrificing long-term valve sealing.

�Conference: Fluid Leak Management Summer MeetingPaper Title: "Re-torquing vs. spring assembly height to re-apply gland load "Oakbrook, Illinois August 26th�Abstract:In the nuclear industry today there are many circumstances when the first course of action of a leaking valve is to re-apply the calculated torque value. In valves that have been exposed to temperature the gland force that is created in re-torquing will not be the same as the “initial” installation value.This presentation will focus on the topic of re-apply gland load on valves in service and discuss alternatives that will result in more accurate gland loading. One method that will be discussed in depth is that of using live loading assembly heights as a measurement of gland load applied. The presentation will review testing data and analyze the bolt-anti seize relationship.One goal of this discussion is to assist the nuclear industry in creating better techniques to handle a loss of gland load. Today it is important to utilize best available packing technology that can enhance AOV/MOV operability without sacrificing long-term valve sealing.
