Reward rules: 3 wealth points for participation, 5–10 wealth points for answers that are close to the correct ones. ........................................................................... What is the rationale behind the requirement in GB150 that the distance between the centerlines of Class A welds in adjacent shell sections should be no less than 3 times the shell thickness and no less than 100 mm? .......................................................................... Answer: It is to prevent the heat-affected zones of the welds on adjacent cylinders from overlapping and causing adverse effects on the material
To avoid the adverse effects on the material caused by the overlapping heat-affected zones of the welds in adjacent cylinders.
This is to avoid the adverse effects on the material caused by the overlapping of the heat-affected zones of the welding joints in adjacent tube sections. (1) Reduces additional bending stress, facilitating cylinder connection, and makes it easier to thin the material when there are differences in thickness. (2) Avoid stress concentration to prevent intergranular corrosion.
