Failures in the reciprocating compressor valves due to poor lubrication, dust and metallurgical properties were causing shutdowns of the compression units and thus pressure fluctuations of 3,000 psig
or more on the pipeline at the ultrasonic meters.
Two pressures (60 psig
and 30 psig
) at three temperatures (90[degrees]C, 80[degrees]C and 70[degrees]C) have been selected because low pressures should be used for indent experiments to ensure indent failures (Table 2, indented pipe).
Later the compressors were back to operating at 95-100 psig
(with 85-90 psig
in converting), and production improved.
If heated water expands and makes the tank pressure 20 psig
, then the pressure at that point is fixed at 20 psig
as long as the water temperature stays the same.
The SCBA is typically rated for a maximum operating pressure of 4,500 psig
and depending upon the volume of the cylinder will have a duration of 30 to 60-minutes depending upon what is specified by the operator.
The machine runs very low (10-15 psig
) steam pressures in wet end dryers.
Other products offered by AFS include the Falcon, a two-stage CNG pressure regulator with a maximum Met pressure of 4350 psig
. The majority of systems used in the U.S.
The company said the models provide inlet pressures of 100 to 200 pounds per square inch gauge (psig
), with discharge pressures of 3,600 to 12,000 pounds per square inch (psi).
Designed for the high pressures and high temperatures typically found in ultrapure processing environments, the Double-Sure dual-containment sight flow indicators are dual-containment sight glasses with a 150 psig
pressure rating and an operating temperature range from -20[degrees]F to 350[degrees]F (-29[degrees]C to 177[degrees]C).
Why you should care: The Series 520 is individually sized and manufactured to ISO 17025 within 0.5 to 50,000 sccm range and within -14.7 to over 500 psig
It pumps a maximum of 4.01 gpm at 3000 psig
(317 rpm) and 2.14 gpm at 6000 psig
The 125-hp compressor is rated for 200 scfm at 15 psig
suction and 4,500 psig
