The issue of pipe end loads on static equipment
Thread Content
One of the responsibilities of those specializing in stress analysis is to calculate the loads on the equipment connections, using these values as a basis for the design of such connections in static equipment. However, in typical projects, it is the owner who initiates the bidding process to have custom-made equipment produced. So how do various engineering companies and equipment manufacturers determine the loads on these connections during the design phase? What are the problems with this approach in practical engineering, and what are some good solutions? There are rewards for participation!
The nozzles of static equipment are subject to stress; each unit has a set of regulations established through consultation between the pipeline stress specialists and the equipment specialists, which determine a precise value for the stress based on the pressure rating and diameter of the pipeline. The equipment discipline and the stress discipline each perform their own tasks, carrying out verification calculations based on this table to ensure that safety requirements are met. In the case of non-standard designs, the equipment department prepares a quotation request document. Simply include the requirement to add this table in the request for quotation. This table can refer to the stress requirements in Appendix D of SH/T3074. However, the stress capacity of class150 is too low; most engineering companies increase the stress capacity of class150 to class300. In other words, the B value for class150 should also be set at 0.6.
