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”.
Dynaflow Research Group has performed the design and analysis for the firewater deluge layout of two large production modules of a floating production storage and
Two of the key challenges currently encountered in operating geothermal wells using conventional steel casings are corrosion and scaling. These problems significantly reduce the lifespan
Hydrogen is considered to be a key element in the energy transition. This molecule is the most notable option for the decarbonisation of hard-to-abate sectors
As part of our responsibilities at DRG, we conduct both standard pressure drop calculations and surge/slug analyses for firewater systems. Our involvement spans various stages,
Geothermal energy is a promising renewable energy source, but it comes with its own set of challenges. Two significant issues in geothermal well operations are
Flow-induced vibrations in piping systems are a critical aspect of mechanical engineering, impacting the reliability and integrity of various industrial setups. The Japan Society of
Introduction In the field of engineering design, the precision of pipe flexibility analysis models is critically important for accurately assessing nozzle loads in steel piping
In 2013, a major incident occurred in a Louisiana chemical plant. In a nonroutine operation, plant operators attempted to start a heat exchanger which had
To understand pressure surges in large piping systems, a good place to start is at home. When you finish washing your hands, turning off the
Brief introduction to piping vibrations Vibrations are an oscillatory motion about an equilibrium. The oscillatory movement causes alternating stresses in the system, which, if excessive

Introduction The flow in the header of a finger-type slug catcher is analyzed using CFD techniques. In order to design a high-performance finger-type slug catcher, it is necessary that the fluid flow in the inlet header manifold is evenly distributed among the different fingers. Analysis A detailed flow analysis by
Combined Pressure Surge and Dynamic Stress Analysis Introduction At BASF Antwerp a steel pipeline was under construction, this pipeline was to be used for the offloading of naphtha from ships arriving at a jetty. The pipeline is 1.6 km long with several pipe bridges. The jetty contains Emergency Release Couplers
Pressure Surge Analysis Introduction An existing power plant of Essent will be extended with a new power plant. The new power plant is based on a Combined Cycle Unit (CCU) which includes the combination of a Gas Turbine with a Steam System. The surface condenser of the new power plant
Combined Pressure Surge and Dynamic Stress Analysis Introduction In the harbor of Antwerp an unloading line was being commissioned for use with cyclohexane. This line features two ship loading arms, located at the end of a jetty. From the loading arms, the unloading line runs towards two storage tanks. Transient

Vibrations had been seen in the piping of a reciprocating compressor plant and the operator of the plant was worried that fatigue cracks could occur. Therefore a study was conducted by DRG to determine how the vibration levels could be reduced and whether they were leading to stress levels exceeding
Accumulators are used to reduce pressure pulsations from reciprocating pumps by adding volume to the piping. In the preliminary design stage the size and position of the accumulator needs to be determined before the piping design is completed. The performance of the system including the pump and connected piping is
Commercially available pulsation analysis software uses either a transient (time domain) or harmonic (frequency domain) solver. A time domain solver is more accurate for determining the pulsation amplitude, but solving in the frequency domain can be orders of magnitude faster. Which solver should you use and why is there a
