I want to use 1/2 inch SS316 tube in my high pressure &
temperature (64 kg/cm2 & 500 deg C)after condensate pot in
1) Is it possible to use 1/2" ss316 tube in high pressure
and temperature line.
Tube manufacturer is local vendor.
2)On sarting the plant, We need to do system fluse that
time condesate is not in the condesate pot so steam is
directly contact with the tube. We have no exact
calculation to know our tube is ok or nor at this time.
We do have a problem in the company that is one PT connected to PlC which is mean 1 out of 1 in PLC system we do have the PAHH is 55 mbar and PALL 8 mbar with a timer of 15 sec for the PAHH the problem started when PAHH goes more than the set point which is 55 it reached up to 71 but due to timer doesn't trip . We force it and we checked everything nothing there . We replaced the transmitter problem still there the reading goes more than the 55 bar the range for transmitte is 0- 60 mbar . So we did loop check , aculaizing valve , wiring all are okay . What the possible causes for this ???
a laways iface problem with brine level transmitter sealing diaphram a laways giving error and maximum reading i made re range and adjust with side glass but during commission it giving gap reading between it and side glass i need help from expert to explain how to calibrate it.

While giving Power Supply of 24 VDC to a Transmitter,why
Shield Terminal is connected either at Transmitter or at
ISB.Why not Shield Terminal connected at both ends.If the
Reason is to avoid Noise interference,which type of noice
that is interfering.Is the Noice from the 24 VDC supply
terminals or from any external source.
Pls.could any one Clarify the following with an example.
1.At What condition Close on Rise and Close on Fall
Pressure Switch contacts are used.
2.If Pressure is abnormal as per set pressure,if connecting
Terminal of pressure switch breaks,how the voltage extends
to Relay base.
3.Are these contacts come under fail safe philasaphy.
If i have 4 Allen Bradely make RS logix 5000 PLC and for
viewing that we are using 4 RS view SCADA for 4 different
packages. Now, I will want to view two packages on only one
