The client is operating multiple ammonia plants with similar cooling water systems made of GRE. Last year, failures were discovered in buried GRE components—specifically, an elbow and a tee—at one of the older plants. A surge analysis conducted by Dynaflow Research Group revealed that these failures were due to an
A new firewater (FW) system is being designed for a Green Hydrogen Elements facility. The plant spans a large area of approx. 2 x 1.5 km and contains multiple critical areas. The piping material is Fiber Reinforced Plastic (FRP). The main firewater ring is of DN250 and DN300 piping. The
A client designed a foam piping system that covers the three tanks in a tank pit in the harbor. The firewater system is directly connected to the general water supply. The main pipeline passes through the foam house where the water is mixed with foam. A manifold divides the mixture
A manufacturer of pulsation dampers requested Dynaflow Research Group to verify the performance of one of its discharge silencer designs in combination with a double rotary lobe gas blower by means of a pulsation study. The scope of the study consisted of a connecting straight pipe spool and the silencer
A fatigue analysis has been done for a reactor feed pressurization drum. The vessel operates under cyclic pressure ranging from 25 psig to 200 psig (1.7 – 13.8 bar), with a design life of more than 5 million cycles. Additionally, it is subjected to 200 full-range cycles from atmospheric pressure
A Glass Reinforced Epoxy (GRE) fire water header, installed on a Liquefied Natural Gas (LNG) jetty, comprises DN700 pipes and is subjected to seismic accelerations. Due to the jetty’s structure, the seismic accelerations provided by the client vary significantly along its length. The fire water header must be evaluated for
The above-ground seawater supply header is designed to transport seawater from two tie-ins in a discharge manifold of the seawater pumps to AGA. A comprehensive static stress analysis was necessary to determine the stress levels within the Glass Reinforced Epoxy (GRE) line. Additionally, it was crucial to define a support
At an LNG terminal, an unexpected settlement of 12 inches of soil, containing several sections of Vacuum Insulated Piping (VIP), occurred. Because the above-ground pipe supports were unaffected by the settlement, the differential displacement between the above-ground supports and the underground soil resulted in plastic deformation of some of the
