With its comprehensive competence for all high pressure-specific aspects concerning the design of the plant Uhde High Pressure Technologies has always forced the technological further development, especially in the area of urea plants as well. Our performance spectrum begins with the process-technical design of components for fertilizer plants and also comprises the specific design of relevant details. Components as well as valves, piping and prefabricated systems are tested for their reliability already before the integration into the plant – the manufacture of completely premounted assemblies does not only increase safety, but also reduces the efforts during the mounting works on site.
The high manufacturing content of Uhde High Pressure Technologies offers safety for the design and quality of the entire plant equipment. Thanks to the intense examination of all materials used, precise calculations and test results potential defects can be detected from the start and eliminated – before they can impair safe and continuous operations in the future plant. The documentation of all manufacturing and test steps as well as all later alterations creates the prerequisite for the precise tracking and analysis of the development process of the plant at a later time.
Control valves belong to our special valves. Hereby, we fulfil all usual standards; our design and flexible construction allows us to meet many customer wishes like closing times, types of actuators and attachments etc. Common nominal sizes of the portfolio are between DN 1”
and DN 16” and can be obtained for all pressure stages of forged bodies.
Hand valves are part of our standard portfolio and can be supplied either individually or in series. In addition, gear actuators are used in case of higher closing forces. Usual nominal sizes of the valves in the portfolio are between DN 0.25” and DN 10”and they can be obtained for all pressure stages for forged bodies.
Check valves assure flow in one direction. Our portfolio comprises checkvalves of different types (with springs, drop shape etc.), which are suitablefor horizontal and vertical installation positions. Usual nominal width soft he portfolio are between DN 0,25” and DN 10” and can be procured for all pressure stages for forged bodies.
Those special valves are increasingly used in case of low-pressure difference sand because of their compact design. When being closed, they allow a flushing through put providing that a continuous problem-free function of the valve is guaranteed even after a longer time of being closed.
The hairpin exchanger can be operated for a pressure range up to hundreds of bars on the tube or shell-side. The exchangers have a big surface and a narrow design to place them into an existing plant.
Analyse valves with a nominal diameter of 2-6 mm are used to tap of medium from the process to check it and assure the quality of the product.The nominal pressure range goes up to 200 bar. The hand wheel with the integrated coupling ensure a proper dosing and long lifetime of the equipment. The body material can be carbon or stainless steeldepending on the medium.
High pressure piping
References up to 16“ HP piping. Bending and welding of pipe classes according to Uhde HPT Standards PN-200, PN-325 und PN-500. Uhde HPT supplies completely prefabricated and tested isometrics, spools and fittings. The high demandson the scope of tests carried out and on the fabrication process can only be satisfied by a comprehensive quality system and properly qualified personnel.
