The Interpack metal saddle-shaped nozzle was invented by the American scientist Norton in 1978, This is a new type of irregular nozzle. In the late 70s, two similar products were also invented. One of them is a metal rectangular saddle-shaped nozzle, the other is a metal ring with a double arc. Two bends on the nozzle increase the mechanical strength of the nozzle and its stability. This type of saddle-shaped nozzle has an increased chemical resistance and mechanical density due to its surface. These properties increase their efficiency and service life by 30%. During cyclic operation, the nozzle elements show a high level of heat resistance.
