A cylindrical shell made of 0.500 inch thick Sa-516 70 material (rated to 20,000 psi at 100°F) is rolled to 48” OD. The inside diameter (ID) ends up at 47”. This cylinder and the seams joining it to any attached heads are fully radiographed, and there is no corrosion allowance. The ASME VIII-1 calculated design pressure … See more The hemispherical head has a simple radial geometry: the depth of the head is half the diameter. With a 47” ID, the required wall thickness is 0.2474”, about half the thickness of the shell. Because the head is thinner than … See more The Semi Elliptical head has an elliptical form – the most common ratio is 2:1 – or the width of the ellipse is twice the depth.
