WebTo optimise a bolted joint, it is recommended to design the clamped length to at least 3 or 5 times the bolt diameter. Increasing the elasticity of the fastener greatly improves the … WebFlanges, bolt, washer and a nut were mapped with an isotropic model of a steel material with Young’s modulus E = 206000 MPa and Poison ratio v = 0.3. The properties of the gasket as a numerical model were inserted to the computer program in the form of deformation characteristics, shown in Figures 5 and ??.

WebThe fasteners with shorter grip lengths and larger diameters will take more of the axial loads when clamped members are displaced. This means that varying stiffness across fasteners leaves the stiffest fasteners more susceptible to overload in certain conditions. WebFlanged joints using low strength carbon steel bolts shall not be used above 400°F or below -20°F. Applications of bolts: i. For flanged joints in piping system where one or both flanges are of cast iron, bolts / studs conforming to ASTM A307 Gr. B and nuts conforming to A194 Gr. 2 are usually used. think baby sippy cup reviews

http://www.piping-engineering.com/bolting-selection-guide-for-bolting-material.html WebFasteners designed to resist both shear and tension should be designed to clause 3.8 of BS EN 1993-1-8, where the tension force is considered to reduce the preload applied to the bolt rather than increasing the force in the bolt.. A worked example of the design of a bolted connection is given in Worked Example 1 in SCI P357. [] DetailinPreloaded bolts are … WebThe dimensions of bolted flange joint is shown below fig.1. Dimensions : Thickness of flange and shell (t f)= 0.5inch, Flange outer radius = 16.7inch, Inner radius of shell = 15 inch, bolt head diameter = 0.75 inch, shell length = 4 inch, Bolt specification : 3/8-inch bolt , 24 threads per inch.
