Pressure and Temperature Limits
The working pressure and temperature at which any
reactor or pressure vessel can be used will depend
upon the design of the vessel and the materials
used in its construction. Since all materials lose
strength at elevated temperatures, any pressure
rating must be stated in terms of the temperature at
which it applies. The standard material of construc-
tion for Parr Instrument Company is type 316 Stain-
less Steel.
Limits for vessels made of other materials and for
other operating temperatures can be obtained from
Parr Customer Service. No attempt should be made
to increase these limits by making alterations or by
substituting components that are not recommended
by Parr Instrument Company. It must also be
understood that lower pressure and temperature
limits may be required for modified reactors and for
vessels made of special alloys.
Limits for vessels will be determined by the physi-
cal characteristics of the vessel material and will be
prescribed on an individual basis.
The maximum working pressure and temperature
for any vessel is governed by the design of the
vessel and the strength of the material from which
it is constructed. There is also a close relationship
between working pressure and temperature since
the strength of any material will normally fall off
as the temperature is increased. Temperature and
pressure limits are also affected by the physical
properties and temperature limits of the gaskets and
seals used in the vessel, and by any valves, gages or
other fittings attached to the vessel. The safe operat-
ing pressure of any system can be no higher than
that of its lowest rated component. All Parr reactors
show the maximum safe operating pressure and
temperature imprinted on the cylinder.
