A Stress Analysis of Pipe Flange Connections
The use of pipe flange connections is standardized in the codes of JIS, ASME, DIN and so on. However, these codes are almost entirely dependent on experience, and subsequently some problems concerning pipe flange connections have been encountered. In the present paper, the distribution of contact stresses which governs the sealing performance is analyzed as a three-body contact problem, using a...
متن کاملassembly performance of a gasketed bolted flanged pipe joint using different bolt tightening strategies
this paper presents the results of the assembly process of a gasketed bolted flanged pipe joint for two different bolt tightening strategies, i.e. asme and industrial using torque control of preload method. the final clamping force is achieved in four and five passes in asme and industrial strategy respectively. axial bolt stress variation, at the end of each pass, individual bolt bending beha...
متن کاملRetained crossbow bolt after penetrating facial trauma.
We present an unusual case of a retained crossbow bolt in the maxillofacial area of a 31-year-old man. While crossbow injuries are rare, this case is of interest because otolaryngologists are often faced with treating retained foreign objects after penetrating facial trauma. These cases are difficult to manage because of the complexity and variety of injuries that can occur during both the init...
متن کاملReduction of Stress Concentration in Bolt-Nut Connectors
Bolt-nut connectors play an important role in the safety and reliability of structural systems. Stress concentration due to unequal load distribution can cause fatigue failure in bolt-nut connectors. In this paper, the stress distribution in bolt-nut connectors is studied using an axisymmetric finite element model. Various geometric designs proposed in the literature were studied to determine t...
متن کاملExploratory study of high-strength, low-cost through-bolt with cross-pipe and nut connections for square and roundwood timber frame construction
Through-bolt with dowel-nut connectors are commonly used in furniture where high strength mechanical connections are required. During early periods of use, dowel-nuts were often called barrel nuts (Eckelman 1977), but the term “dowel-nut” is more descriptive, and the author has referred to them as such in the above and all subsequent publications (Eckelman 1989, 1999; Eckelman and Erdil 2000). ...
