When it comes to the fluid handling industry, there is one publication that every engineer has heard of, studied, and refers to often regarding the flow of fluid through valves, pipes and fittings, and that document is the CRANE Technical Paper 410 (TP-410). Intended for use by a wide range of plant engineers, technicians, maintenance personnel, and plant operators, the TP-410 has become the quintessential guide in selecting the correct equipment and parameters when designing and operating any piping system. This year marks its 75th anniversary, and since its inception in 1942, the TP-410 has undergone multiple revisions and updates to remain relevant to generation after generation of engineers.
Crane was founded in 1855 by one man, Richard Teller Crane, who built his company on a set of values that have guided its employees for over 160 years. Since then, Crane has been the world’s leading innovator and pioneer of practical flow control solutions, addressing and exceeding the needs of the industry, enabling customers to operate better, faster and safer. With a heritage of innovation built upon a dedication to technical design and manufacturing excellence, combined with standards and values that center on honesty and fairness, it’s no wonder the company was behind such an influential and educational publication as the TP-410.
It was Crane that realized the importance of truly understanding the principles behind the flow of fluids in order to effectively design piping systems and properly select the most appropriate valves, pipes and fittings for that system. The TP-410 was a product of this discovery that would help engineers for years to come, its relevance never weakening as new applications and environments were explored.
In recent years, the global industrial base has continued to expand and fluid handling is still at the heart of new, more complex processes and applications. Today, almost every conceivable fluid is handled in pipe during its production, processing, transportation, or utilization. In the current decade of new technologies, heat-transfer fluids from solar plants, mineral slurries, and new chemical compounds process pressures and temperature much more extreme than ever before. And as new technologies, fluids and applications were introduced to the industry, the TP-410 provided updates, adding new chapters and technical references. The current edition consists of seven chapters that cover the theory and calculation methods used in the design of piping systems as well as the sizing and selection of valves, pumps and fittings, and is published in two versions Metric (using SI units) and ASME.
In recognition of the more complex processes and applications which engineers encounter, in the late 1990s Crane partnered with Engineered Software, Inc. to produce a branded software product to complement the TP410 Publication. This software, Flow of Fluids Premium, is piping system simulation software for use in the design, optimization and troubleshooting of fluid piping systems. The history between Crane and Engineered Software goes back much further than the nineties however, to 1978 when two innovative and driven engineers with an early microcomputer and a 1970’s version of the TP410 started developing software to calculate pipeline headloss, followed by software for pump, control valve, flow meter, and orifice calculations. Over the past 39 years, Engineered Software has continually developed features and functionality to improve communication between design engineers, plant managers, and system engineers and operators through software analysis of fluid handling operations. Flow of Fluids allows users to model fluid piping systems on their computers, before costly downtime or product quality issues occur. The current program analyzes open or closed loop systems containing either liquids or gases, supports the design of new systems or modifications to existing systems, assists in the sizing and selection of equipment, troubleshoots to find the root cause of operational problems, and identifies opportunities for system optimization. It gives engineers a clear picture of the entire system, demonstrating how all equipment works together, rather than focusing on individual pieces of equipment. Through this software, engineers simply enter design details (equipment and pipeline data), specify operating conditions, run the required calculations, simulate operating scenarios, and troubleshoot existing systems or design new systems based on the analysis provided.
