4570 HP/HT Pressure Reactors Parr Instrument Company
PREFACE (Continued)
Intended Usage
This system has been designed for use as
a high pressure reactor system. It has been
designed, built, and tested to strict physical
and electrical standards. However, it is the
user's responsibility to install and operate it in
conformance with local pressure and electrical
codes. If this equipment is used in a manner
beyond its intended usage, the protection
provided by the equipment may be impaired.
User’s Responsibility
All Parr Reactors and Pressure Vessels
are designed and manufactured with great
care to assure safe operation when used
within their prescribed temperature and
pressure limits. But… the basic responsibility
for safety when using this equipment rests
entirely with the user; who must:
1. Select a reactor or pressure vessel
that has the capability, pressure rating,
corrosion resistance, and design features
that are suitable for its intended use. Parr
engineers will be glad to discuss available
equipment and material options with
prospective users, but the final
responsibility for selecting a reactor or
pressure vessel that will perform to the
user's satisfaction in any particular reaction
or test must rest with the user - not with
Parr.
In exercising the responsibility for the
selection of pressure equipment, the
prospective user is often faced with the
choice between over-or under-designed
equipment. The hazards introduced by
under-designed pressure vessels are
readily apparent, but the penalties that
must be paid for over-designed apparatus
are often overlooked. Recognizing these
criteria, Parr reactors and pressure vessels
are offered in several different styles, each
designed
for convenient use in daily
operation within certain temperature and
pressure limits, using gaskets, closures,
and other elements carefully selected for
safe operation within the limits specified
for that design. But in order to preserve
the validity of these designs, all
temperature and pressure limits must be
observed, and no attempt should be made
to increase these limits by making
alterations or by substituting components
which are not recommended by Parr
Instrument Company.
2. Install and operate the equipment within
a suitable barricade, if required, with
appropriate safety accessories and in full
compliance with local safety codes and
rules.
All standard Parr pressure vessels are
provided with either a suitable relief device
or a means to attach one (typically in the
form of a plugged opening). When a
pressure vessel is delivered without a
pressure venting device, it is the
customer’s responsibility to provide
pressure relief in order to protect the
operator and the equipment from
destructive high pressures. If you need
more information or need help in selecting
a proper relief device, please contact Parr
Instrument Company.
3. Establish training procedures to
ensure that any person handling the
equipment knows how to use it properly.
4. Maintain the equipment in good
condition and establish procedures for
periodic testing to be sure the vessel
remains structurally sound.
Unpack Carefully
Unpack the equipment carefully and check
all the parts against the packing list. If
shipping damage is discovered, report it
immediately to the delivering carriers. The
vessels, heater block, and controller may be
packed separately for convenience in
shipping, but these parts are easily
reassembled. Examine the components
closely for any loose parts or shipping damage
and be sure to check all layers of packing
materials thoroughly so as not to overlook any
parts which might otherwise be discarded.
