What guidelines should be followed when arranging spherical tanks? Answer: The following guidelines should be adhered to: First, for the geometric dimensions of the shells formed by pressing, larger (1) structures should be used, in order to minimize (2) and reduce the amount of work required for installation ； II. According to the specifications of the steel plate, strive to increase the thickness of the sheet material (3) ； III. Few specifications, good interchangeability ； IV. It enables all adjacent (4) elements to be staggered from each other ； V. The distribution of (5) should minimize assembly stresses, restraint stresses, and residual stresses, while ensuring a uniform distribution. A. Utilization rate ； B、Weld length ； C. Weld position ； D、Spherical shell plate ； E. Longitudinal weld ； ---------------------Answers: 1. D 2. B 3. A 4. E 5. C. Answers: I. For press-formed spherical shell plates, it is advisable to use a structure with larger spherical shell plates, in order to minimize the length of welds and reduce the amount of work required for installation ； II. According to the specifications of the steel plates, strive to increase the utilization rate of the materials ； III. Few specifications, good interchangeability ； IV. It enables all adjacent longitudinal welds to be offset from each other ； V. The distribution of weld positions should minimize assembly stresses, restraint stresses, and residual stresses, while ensuring a uniform distribution. 1. Comments: This question is about spherical containers and is an optional question. The arrangement of elements in spherical containers is a unique challenge encountered in their design; an appropriate arrangement can help save materials, facilitate manufacturing, and ensure the safety of such containers. Therefore, this problem is the most fundamental one in the design of spherical containers.
