DESCRIPTION OF EQUIPMENT
The Series SA, and SA-P units consists of an ASME Code
stamped steel receiver (permitting operating under pressure up
to 15 psig [1.0 Bar] and equivalent temperature up to 250°F
[121°C]). Series B35 centrifugal pump(s) designed for 2 ft. (0.6M)
NPSH, corrosion inhibitor (anode), water level gauge, ther-
mometer, pressure relief valve, thermostatic air vent trap, com-
pound gauge, valve(s) in pump suction, and a drain (gate)
valve. Occasionally, Series SA units are fully vented; these
receivers feature ASME Code construction except the code
stamped is omitted. In addition to the above components, the
Series SA-P employs a proportioning regulator and valve (elec-
tric or pneumatic). The Series SA unit uses float switch controls.
Control panels and components supplied per specification.
When Series SA units are furnished with ASME Code stamped
receivers, relief valve and air vent trap to permit pressurization,
then the receiver inlet is directly connected to the outlet of the
steam absorption unit or other steam process equipment with-
out steam traps in the return line. When used in this manner, a
separate SA unit is usually required for each independently
controlled heating unit.
It is, however, possible to use a single SA unit with multiple
heating units. Detailed information and drawings will be fur-
nished on request.
The relief valve on the unit is set at 15 psi (1.0 Bar) and rated at
1900 pph (862 Kg/hr) steam. Any additional system protection
must be provided as required by others.
PRELIMINARY INSPECTION
Assure that there is no shipping damage.
Assure that nameplate ratings agree with job specifications and
actual conditions.
