Contact pressure distribution in joints formed by V-band clamps
V-band clamps offer an efficient clamping solution in diverse applications including process equipment, exhaust systems and air handling. This paper studies the distribution of interface contact pressure between the V-band and flange when the coupling is established. The determination of the contact area and pressure distribution in a joint is essential information, as it determines the integri...
متن کاملEffect of Residual Stress on Failure of Tube-to-tubesheet Weld in Heat Exchangers
In a shell and tube heat exchanger, the failure of tube-to-tubesheet welds results in high-pressure water jet which erodes the refractory in front of the tubesheet. Finite element method was employed to simulate the welding process and post weld heat treatment (PWHT) to find the factors affecting the failure in tube-to-tubesheet weldments. Residual stresses in two different geometries of tube-t...
متن کاملPredicting and Determining the Contact Pressure Distribution in Joints Formed by V-band Clamps
V-band clamps are utilised in a wide range of industries to connect together a pair of circular flanges, for ducts, pipes, turbocharger housings and even to form a joint between satellites and their delivery vehicle. In this paper, using a previously developed axisymmetric finite element model, the impact of contact pressure on the contact surface of the V-band clamp was studied and surface rou...
متن کاملEffect of Contact Pressure and Frequency on Contact Heat Transfer Between Exhaust Valve and its Seat
The hot gases produced by the internal combustion engines passes through the exhaust valve and causes high temperatures in the exhaust valve and its seat. To avoid damaging the exhaust valve, heat must be transferred from the valve to its seat during the contact they make at the opening and closing cycle. Heat transfer rate from the exhaust valve to its seat is a function of many factors. One o...
