New Level of Expandable Connector Qualification Helps Minimize Operational Risk in Solid Expandable Liners
All Days, 2007Co-Authors: Lev Ring, Philippe Deletombe, Patrick L. York, Robert V. BakerAbstract:Abstract Expandable Connectors continue to be the Achilles Heal of solid expandables due to the simple nature that the Connectors need to sustain their tensile, compressional and sealing integrity, before, during and after expansion. Solid expandable products such as monobore liners and monobore clads, which push expansion ratio requirements to 20% and toward 30%, require Connectors with qualification needs that exceed earlier product applications. The API and ISO qualification bodies are now addressing the need for standardization recommendation procedures for the testing and performance specifications of solid expandable system tubulars and their connecting devices. Connector failures and inconsistent reporting methods of specifications of solid expandable systems' performance envelops have driven the industry to attempt to apply standard methods of API Connector qualification. Even applying conventional testing and qualification methodology for expandable Connectors cut on seamless tubulars fell short of thoroughly qualifying these Connectors for use in the extreme environment of cold working connected tubulars in situ. Therefore, a conventional, four-quadrant service load performance envelop has been adapted and developed for the new requirements. Even expansion in "fixed-fixed" conditions has been added to help ensure consistent performance in downhole service. This type of Connector qualification has historically rarely been conducted, and then only on a very small range of the possible expansion ratio or for only one size and type of Connector. This paper describes the need, the methodology and the processes required to qualify Connectors to this level. This extensive testing and qualification process has yielded Connector performance ratings that can be verified with empirical data for every size and Style Connector for carbon steel as well as CRA tubular materials. With solid expandable products being used in a wider and broader arena of applications with associated high risk and expensive consequences, it is critical to qualify each size and type of expandable Connectors, clearly document these qualifications with both theoretical modeling and empirical data and be prepared to provide the end user with sufficient proof of the expandable Connector's performance ratings. This paper explains how this new methodology provides this level of proof of performance to the end users. Introduction The testing of expandable Connectors has been sparse in the past due to the cost of a full-scale program. For instance, if the process described in this paper is followed, the cost of qualifying a single size of an expandable Connector can be $500,000 U.S. or more. This high cost stems from an extensive process that includes the following:Procure ~1,500 feet of expandable casing300 feet for lab tests1,000 feet for downhole test200 feet for back-upCreate test samplesTwo to four, 20-foot samples for cone testing~Ten to 12, ten-foot samples with Connectors for Connector tests in lab~30, 40-foot samples for downhole testPerform quality testing on pipe before and after expansionTensile loading on pipe without pressureInternal Pressure only on pipeExternal Pressure only on pipePerform make & break testing on lab samplesw/max dopew/min dopePerform four-quadrant testing on several lab samplesPerform internal pressure test under bending (dogleg severity test)Perform destructive testing on samplesCollapse pressureBurst pressureTension

Disinfection of Male Luer Style Connectors for Prevention of Catheter Related Bloodstream Infections Using an Isopropyl Alcohol Dispensing Cap
Journal of Medical Devices, 2010Co-Authors: James P. Kennedy, Richard A. Lasher, Donald Solomon, Robert HitchcockAbstract:Bacterial colonization of needleless injection sites (NISs) frequently results in catheter related bloodstream infections (CRBSIs). Hospitals have instituted protocols aimed at disinfecting NIS prior to access. Furthermore, several manufactures have developed devices that facilitate disinfection of NIS. Despite these steps, the incidence of CRBSI is still alarmingly high. Currently, there is no protocol or device intended to disinfect male luer Connectors such as those found on IV tubing that are commonly coupled and decoupled from the NISs. Since these IV tubing Connectors directly contact the NIS (which have been repeatedly shown to have varying levels of bacterial colonization), it is highly likely that they, too, will have varying levels of contamination. In order for disinfection of the NIS to be effective, the IV tubing Connector must also be disinfected. Our design goal was to develop a device that could be used to disinfect a male luer Style Connector without allowing antiseptic into the inner lumen of the male luer. We designed a three component system that utilizes a silicone sealing cone to seal the male luer, a reservoir foam that holds 70% isopropyl alcohol (IPA), and a reaction force foam that increases the seal pressure of the sealing cone while the reservoir foam is compressed delivering the IPA to the outside surface of the male luer post. Sealing cone geometry was optimized using a custom built seal pressure test apparatus. Reservoir and reaction force foam functional parameters were assessed using an Instron test apparatus. A two phase compression stroke was designed into the device to allow for sealing and dispensing of IPA. An IPA transfer test was used to assess the transfer of disinfectant from the reservoir foam to a liquid filled male luer Connector (modeling an IV tubing Connector). No disinfectant was found to be transferred from the device to the inner lumen of the IV tubing Connector model (n=30). To test the efficacy of the device on reducing bacterial count on the male luer, a disinfection study was performed using the optimized device. Male luers were immersed in bacterial suspensions of S. aureus, S. epidermis, P. aerginosa, and E. coli. A 4 log reduction compared with a positive control was found in each sample treated with our disinfection cap (n=120). In conclusion, we developed a device that effectively delivers an antiseptic to a male luer Style Connector without leaking any antiseptic to the inner lumen of the luer post
