WebNov 1, 1995 · When the first bolt is tightened the gasket compresses and the flange distorts. (Assume all bolts are hand tight to prevent flange rocking that would occur if only one bolt was tightened.) When an adjacent bolt is tightened, the gasket compresses and the flange distorts further. Webbetween the flanges or whether the flanges are in metal-to-metal contact has to be decided here. For the gasket type selected "correctly", first details on the long time behavior are required. This concerns the resistance against the medium to be sealed up, the change of the tightness behavior and the corrosion behavior at given flange material and

WebJul 1, 2006 · A more detailed flange stress variation phenomena during bolt up as per bolt tightening Sequence-1 and 2 for each bolt is plotted in Fig. 9. During bolt tightening Sequence-1, almost, same stress variation behaviour observed along all the locations. Both tensile and compressive (sinusoidal stresses variation) pattern showed relaxation. diamond art pots

WebOrdinary bolts have poor shear resistance and can be used in secondary structural parts. Ordinary bolts only need to be tightened. Ordinary bolts are generally 4.4, 4.8, 5.6 and 8.8. High-strength bolts are generally 8.8 and 10.9, of which 10.9 is the majority. Level 8.8 is the same level as 8.8S. The force performance and calculation methods ... Webiv.
