The recommended velocities for fluids’ transportation must be updated periodically to obtain the optimum value of the pipe diameter in the current economic conditions
To arrive at the optimum diameters for pipes, the heuristic criteria of recommended velocity has been used in the past. However, the values used as criteria are not updated frequently, despite changes and fluctuations in the economy. Because the recommended velocities are likely out of date, the resulting pipe diameter values can be far from reality.
In the article “Updating the rules for pipe sizing” , an update of the recommended velocity was presented, based on the energy costs from 2008. This analysis showed that the recommended velocities are highly sensitive to energy and material costs. In this article, the recommended velocities have been updated based on 2017 prices for energy and current prices for highly used materials in the industry.
Optimizing the pipe diameter
Given the uncertainty of fossil fuel depletion and the volatility in its prices, there is a growing general necessity to optimize processes in an effort to locate economic alternatives where operating and investment costs converge to a minimum that increases efficiency. One way to reduce…
