Welcome to our world of high pressuresIf matter is compressed to several hundred
or thousand times the atmospheric
pressure, its properties partially change
dramatically and there are exciting options
of using pressure as a tool.
For more than 75 years we have been
researching our world of high pressure
and we have realized: The more we know,
the more chances arise for us and for all
people accompanying us on our way into
this fascinating world.
Due to decades of experience and the
cooperation with all important licensors
like Stamicarbon, Snamprogetti, Urea
Casale or Toyo Engineering, Uhde High
Pressure Technologies has become one
of the leading suppliers in the fertilizer
field.
Uhde High Pressure Technologies designs,
fabricates and supplies valves, fittings
and prefabricated piping for every well-
known licensor and customer.

Top Technology and Top QualityUhde HPT manufactures all types of
valves which are required in the
HP section of an urea plant.
All valves are completely
free of copper-bearing
metals. Recent optimiza-
tion of the product lines
covers a modular design in
order to easily and cost-effi-
ciently adapt the valves to the
varying piping standards of plant
contractors. Development is ongoing for
the application of new alloy totally avoid-
ing the well-known corrosion problems in
HP urea service.
Due to the highly aggressive nature of
the process media at high pressures of
200 bar and temperatures of 180C the
urea process which seems to be simple
demands highest technical standards.
This concerns the valve technology in
the synthesis loop in particular.

Control valvesThe control valve is an essential constitu-
ent for the process. This valve is charac-
terized by high speed, high positioning
accuracy and a long service life.
High accuracy is achieved by an electronic
valve positioner designed for rapid signal
conditioning. The positionof the valve stem
is measured using a position transmitter
in order to obtain great reproduction.
Many years of experience in the design-
related arrangement of the seat and the
cone and in the selection of the appro-
priate materials led to the achievement
of long service lives. The simple and
robust structure of the valve and the con-
trol parts results in the highest degree of
functional safety.
Flow measurements according toDIN EN 60534-2-3

with heating channels, full stroke time less
than 6 sec. for opening and 6 sec. for closing
Control valves are part of control
loops ensuring save and reliable
production plant and so they must
be perfectly adapted to the individual
process parameters. We need your
specifications in order to prepare a

HP piping Fabrication of HP piping for Urea plants
References up to 16" HP piping
Bending and welding of pipe classes
according to Uhde HPT Standards
PN-200, PN-325 und PN-500
All piping must be corrosion-resistant
and should also satisfy the particularly
stringent requirements dictated by the
location in the urea plant and by the
process licensor.
Uhde supplies completely prefabricated
and tested isometrics and spools. The
high demands on the scope of tests car-
ried out and on the fabrication process
can only be satisfied by a comprehensive
quality system and properly qualified
personnel. This means, for example,
that each weld has to be X-rayed several
times and that corrosion resistance has
to be tested according to the instructions
prevailing for each combination of welding
filler metal, piping and fitting material.
Heat exchanger
The hairpin exchanger can be operated for
a pressure range up to hundreds of bars
on tube- or shell-side. The exchangers
have a big surface and a narrow design
to place them into an existing plant.
Controlling aggressive fluids
The standard method of testing stainless
steel used for urea plants is the Huey test,
however, depending on the materials, the
Streicher test or Strauss test can also beapplied.
