Q. Explain working of Nozzles?
Nozzles supporting agitators, pumps, or other mechanical equipment, shall be suitably reinforced to withstand the mechanical loadings, specified by the device manufacturer. Likewise, nozzles for pressure relief devices shall be designed and reinforced for thrust reaction. Use of heavier nozzle necks, conventional reinforcing pads with properly contoured fillet welds, and formed heads of appropriate stiffness, are the elements that result in a design suitable for an infinite number of cycles. Gussets shall not be used to strengthen, stiffen, or reinforce nozzles, unless demonstrated by calculations to be suitable for the specified cyclic life or thermal condition.
