The gas storage tank is fabricated by bolting together two half cylindrical thin shells and two hemispherical shells as shown. If the tank wall has a thickness of 50 mm for cylindrical and hemispherical shells, The bolts were installed as 40 bolts/meter. The tank and the 25 mm diameter bolts are made from material having an allowable normal stress of 150 MPa and 250 MPa, respectively. The tank has an inner diameter of 4 m. What is the maximum pressure that tank can contain.
The gas storage tank is fabricated by bolting together two half cylindrical thin shells and two hemispherical shells as shown. If the tank is designed to withstand a pressure of 3 MPa, determine the required minimum thickness of the cylinder and hemispherical shells and the minimum required number of bolts for each hemispherical cap. The tank and the 25 mm diameter bolts are made from material having an allowable normal stress of 150 MPa and 250 MPa, respectively. The tank has an inner diameter of 4 m.
The pressure tank is fabricated from spirally wrapped metal plates that are welded at the seams in the orientation shown. The tank has an inside diameter of 700 mm and a wall thickness of 8.9 mm. For a gage pressure of 1.27 MPa, determine (a) the normal stress perpendicular to the weld (use positive for tension, negative for compression) and (b) the shear stress (absolute value) parallel to the weld. Assume = 51. s Answers: (a) Normal stress= (b) Shear stress - MPa MPa
Deep sea pipelines are used to transport oil and gas across large distances, at depths greater than 2km. The pipes are typically made from high grade steel plate (X80), which is bent, then seam welded to produce a section of pipe. During installation, sections of this pipe are welded together. In deep water, installation is usually conducted using the J-lay system. In the J-lay system, a string of pipe is hung from a barge, and allowed to fall to the sea floor, forming a J-shaped string. As the pipe is lowered, new sections are welded to the end of the string, and the barge moves forward. This system enables a good degree of accuracy in placing the pipe, and requires a less powerful ship than other laying systems. It does, however, place significant loads upon the pipe itself. 2000m Tmin=400m Pipeline m
