My friend, Mr. K. Thirunathan Ntpc Ramagund, all your
points are correct, except
3.FINALLY IT REDUCES HIGH PRESSURE INTO LOW PRESSURE AND
AVIOD VIBRATION IN IMPULSE LINES.
In this point, avoiding vibration is ok, but how the high
pressure will get reduce to low pressure? If like, how can
we use that pigtail for high range pressure
gauge/transmitter?
According to me, this pigtail will be used to avoid the
sudden pressure impact on the gauge/transmitter, created in
the process where it fixed. Because the boiler/vessel/steam
line will be high pressurized, so there is the chances for
sudden variation, the pigtail will safe the instruments if
it used.
