An inherently balanced system is worth the investment. How do you get equal flow to components in your piping system with minimal interruption and fine tuning of control valves? In systems with multiple branches and loops, the flow will take the path of least resistance. In an uncontrolled system, there will be an inherent difference in flows to components with a common source.
Learn the differences between the HI and Wilson methods. Correctly sizing and selecting a pump is crucial in any situation, especially when efficiency and cost considerations are in play. Improperly sized pumps can lead to additional wear and tear, performance and cavitation issues, and an overall decrease in the life expectancy of a pump. One must also factor in the cost of replacement and the possibility of downtime for the system to repair a pump that is incorrectly sized.
Meet Steering Committee Member, Christy Bermensolo, CEO of Engineered Software, Inc. Joining ESI in 2006 from Intel Corporation, where she advanced from a chassis and component design engineer to a senior engineer on Thermal and Mechanical System Integration. Her work spanned from large server systems, including the first IA-64 bit server, to enabling components and desktop architecture design. During this time, Bermensolo is credited for developing a patent for a connector (#6,146,176) used in the interconnection of the CPU to Memory Module on the first IA-64bit Itanium server.
In recent years, plant processes have become more intricate with a host of supervisory control and data acquisition (SCADA) solutions to achieve the precision control necessary to deliver a finished product. Control rooms have upgraded from analog to digital, with displays giving the operator data.
When it comes to pumping systems that have varying demands, many engineers are hesitant to size the pump to less than the highest possible load. While this is certainly conservative from a flow standpoint, the downside is that additional costs are incurred to mitigate what might be a small risk. To assess that risk and make an informed decision, take a Monte Carlo approach, which can save considerable money.
There are 13 areas included in a process safety management (PSM) plan. The piping system model can be of value in all aspects of the PSM, but the areas of greatest impact are in:
process safety information
process hazard analysis
operating procedures and practices
investigation of incidents
Process Safety Information
Working with chemicals can pose a host of dangers. Those in the process industries must take every step possible to protect employees and others from hazardous conditions.
The U.S. Occupational Safety and Health Administration (OSHA) issues and enforces standards designed to increase worker safety, including for facilities that process chemicals. Other countries have similar programs, and the United Nations oversees the Globally Harmonized System for Hazard Communication in an effort to protect workers internationally. One mandated OSHA standard is the Process Safety Management (PSM) of Highly Hazardous Chemicals (standard, 29 CFR1910.119) to prevent the unwanted release of hazardous chemicals that could cause serious exposure.
Knowing the flow rate within a fluid piping system is one of the most useful measurements in understanding system operations.
The equipment used to measure flow rates is typically maintained and calibrated by the plant instrumentation and control groups. Facility flow meters typically monitor custody transfer or are used as the primary elements of flow control circuit.
