There are three types of Flow Nozzles ■ ISA 1932, with corner taps ■ ASME long radius, low beta ratio (0.20 < (3 < 0.5), with throat tap ■ ASME long radius, high beta ratio (0.25 < (3 < 0.8), with radius taps (D & D/2) ASME long radius, low beta ratio Nozzle with throat taps is used in steam turbine performance test As per ASME PTC-6 code.
ISA-1932 nozzle can be mounted with carrier ring or in between flanges with corner taps. Long radius nozzle are normally with weld-in branch pipe with radius taps. Can be also mounted in between flanges.
To avoid welding of dissimilar metals, nozzles are also installed in the pipe with holding ring.
