Fluid Handling for the Future: Over 80 Years of TP-410 Flow of Fluids and Saunders' Dedication to Education and Expertise

As the global industrial landscape continues to evolve in the 21st century, fluid handling remains at the core of increasingly complex processes and applications. Today, nearly every imaginable fluid—from heat-transfer fluids in solar plants to mineral slurries, cryogenic applications, and advanced chemical compounds—is transported through piping during production, processing, transportation, and use. With new technologies driving innovation, modern processes now operate under far more extreme pressures and temperatures than ever before.

For over 80 years, one publication has stood as a cornerstone in the fluid handling industry, familiar to virtually every engineering professional and student— Crane’s “Flow of Fluids Through Valves, Pipe, Pumps, and Fittings”, Technical Paper TP-410. This publication has served as an invaluable educational resource, guiding generations through the principles of fluid flow in piping systems. At Crane, we are immensely proud of the impact TP-410 has made on our industry, reflecting our commitment to continuous learning and innovation.

A key driver of Crane Saunders' continued leadership in fluid handling solutions is its unparalleled technical expertise, particularly in polymer technology. Saunders’ innovations, such as diaphragms constructed with multiple layers of rubber and fabric reinforcement, optimize flex performance even in high-cycle applications. These advanced diaphragms feature sealing ribs on the wetted face, providing enhanced leak-tight capabilities while reducing closure torque requirements. Furthermore, Saunders’ proprietary formulations, manufactured exclusively in-house, now in a modern new facility in Cwmbran, UK, ensure exceptional abrasion and corrosion resistance, demonstrating how ongoing research and development align with the educational foundation laid by the TP-410.

Committed to Innovation

In addition to its advanced diaphragm technology, Saunders is dedicated to solving customers’ toughest challenges through innovative designs in its Aseptic Diaphragm valves and Ball Valves. The Saunders Ball Valve, featuring a slot-in cartridge design, allows for quick removal on the horizontal plane, reducing maintenance time by 50%. This user-friendly approach not only exemplifies practical engineering solutions but also reinforces the educational principles championed by TP-410, where innovation meets real-world application.

In response to today’s growing demands, Crane Company, Process Flow Technologies, has made significant updates to the renowned TP-410 technical resource. The most recent edition introduces several key additions, including a new chapter on "Sensible Heat Transfer," reflecting the latest advances in heat management. The updated TP-410 also features expanded content on critical fluid-handling components such as pumps, control valves, flow meters, and a variety of valves and fittings—essential tools for managing modern fluid systems, including those in cryogenic applications. We are confident that these updates will provide significant value and be widely appreciated by professionals and students alike, further strengthening our commitment to education and innovation within the industry.
