For a full-liquid evaporator used in cooling systems, where the refrigerant outlet B uses a reducer fitting, how should the size of the connecting pipes be chosen, what should the extension length be, and how should the openings at pipe end B be reinforced?
Only the large end portion connected to the housing needs to be calculated. The so-called opening reinforcement refers to the need to reinforce a housing due to the presence of openings...
When only the big-end is considered, pay attention to the effective overhang length
The reducer is selected according to standards, and the reinforcement of the pipe fittings is calculated in accordance with regulatory requirements
The reference standard for reducing joints is GB/T12459, but no information regarding the length of the straight sections is provided in this standard. Could you advise on how to find this information? Do you mean the length of a long straight segment by the extrusion length?
