The basis for reliable fiberglass piping systems are the specifications that lay out the requirements to the system regarding material quality, engineering, installation and inspection and test plans.
Cooling water installations are designed to cool an installation in the event of a nearby fire. This can be necessary if the contents of a tank or pressure vessel are likely to expand with heat. We can use BOSfluids to perform hydraulic calculations of steady state flows in a cooling water system that includes many deluge nozzles (sprinklers).
The latest BOSfluids release brings a new, low-cost license option that is aimed at users who are primarily interested in performing steady state analyses.
Dynaflow Research Group has recently performed several level 1 and 3 assessments resulting in either extended service lifetimes or recommendation of component replacement.
The new BOSfluids release brings many small and large improvements to its user interface that make it even more efficient and versatile.
Dynaflow proudly presents a new online training course: “Pipe Stress Analysis”.
A comprehensive stress and surge analysis was performed for the firewater piping system of an LNG plant located in South America. The system, constructed using Glassfiber Reinforced Epoxy (GRE) pipes, underwent a dynamic response analysis to account for the largest and most critical unbalanced forces. Surge Analysis The existing firewater
This case study examines the detailed fatigue stress analysis conducted on a heat exchanger used to heat Polyol before it entered a refinery reactor. The complex 8-pass, U-tube configuration with a flanged stationary tube sheet required thorough investigation to ensure operational integrity and longevity. Analysis Methodology Engineers identified and analyzed
In this case study, a number of critical sections in an already installed fire water system were selected for review. At the time of the analysis, earlier on-site interventions had already been made, motivated by pipe failures. The analysis aimed to determine if additional interventions were necessary. Analysis Based on
This case study describes the stress analysis performed on a firewater piping system located in the Middle East. The system was constructed using Glassfier Reinforced Epoxy (GRE) pipes. Most of the piping was buried underground and included several connections to above-ground steel piping, fire hydrants, and similar equipment. Analysis The
Introduction At a Flow Station in Nigeria, vibration issues were observed in the suction and discharge headers, as well as the pump recirculation line. To address these concerns and identify potential underlying issues, DRG conducted a comprehensive pulsation analysis combined with a mechanical response assessment. Analysis A stress model was
Introduction In this case study, we explored the pulsation and vibration phenomena at a gas compression station equipped with four centrifugal compressors. These compressors generate flow pulsations due to the action of the impellors, which can excite the system’s acoustic and mechanical natural frequencies. To understand and evaluate the system’s
Introduction During the start-up and normal operation phases of a Gasoil Hydrofiner system, significant vibrations were observed in its piping. These vibrations, described as “large amplitude,” were particularly concerning. The unit’s piping was divided across four separate pipelines. Analysis Upon examining the system under various process conditions, it was determined
Pressure surges ocurr in piping systems whenever there are sudden changes in flow resistance from steady operation. Surges can cause significant damage, also at locations far removed from where they are initiated. For large or complex piping systems, this can make their impact challenging to predict without specialist analysis. Dynaflow
Introduction In this case study, we encountered undesirable vibrations in the downstream line of an angle control valve within a wash oil line. Initially, the upstream wash oil boasted a pressure of 150 bar and a temperature of 400°C. However, downstream of the valve, there was a significant pressure drop
Introduction A surge analysis and static stress analysis were necessitated for an FRP ballast water system following a prior incident to prevent its recurrence. The ballast system’s function was to redistribute water among compartments to balance oil storage. Analysis Surge Analysis One of the main objectives of the surge analysis
Hydrogen generation equipment has an inherent risk for internal explosions, posing an issue to safety. The hydrogen piping and equipment are required to withstand internal explosions by limiting the damage to deformation. Although this disqualifies the component for future use, safety is not compromised. The objective was to find a

Why Pay Attention to a Line Filling Process? During a start-up/line filling process a wave front of fluid progresses it’s way through the empty* parts of the line. However, when this front is required to change direction through bends the change in momentum generates an unbalanced force, this unbalanced force
What is Hogging and Sagging and what are the effects on piping? When waves pass over the length of a ship, the ships profile rises and bows following the peaks and troughs of said wave due to the changes in bouyancy along the length. This effect is known as hogging
For an ammonia plant in Western Australia, cooling water is supplied by a Sea Cooling water (SCW) as well as a Fresh Cooling Water (FCW) system. Both piping systems were constructed out of fiberglass material with pipe diameters of up to 72”. Heat exchangers acts as the interface between the
