Standard ASME B16.5 Flanges: Bolt Tightening and Target Loads

Using the approach outlined here, piping engineers can select the most appropriate bolt-tightening technique based on pressure class and flange size, and calculate the required torque or tool pressure if hydraulic tensioning tools are used In the majority of industrial…

Data connectors for Ethernet and Profinet

The new, two-piece M8 circular connectors for data transmission (photo) are well suited for compact devices, such as SCADA operator interfaces or camera systems. The four-position socket contacts feature D-coding and enable data transmission at up to 100 Mbps (CAT5…

The Changing Face of Simulation

Easier-to-use features and simplified integration lead to new applications for simulation software Simulation software and its capabilities have come a long way in recent years. The latest versions include easier-to-use and more advanced features, increased computing speeds and simplified integration…

Direct, in-situ assessment of critical catalyst properties

The new in situ catalyst-characterization system (ICCS; photo) delivers high-performance test capabilities for the reliable and industrially representative investigation of catalyst behavior. By integrating with the PID Microactivity Effi catalyst-screening system, the ICCS allows researchers to efficiently quantify the impact…

Interpreting Normalized Profitability Metrics

Normalized profitability metrics provide a basis for comparing the efficiency of capital investments, but they are often misunderstood. New interpretations of these metrics can help engineers to make more informed decisions In a financial sense, a large capital project can…

Rugged scales handle logistical tasks

The AGB and AGF range of bench and floor scales (photo, p. 32) feature an integrated indicator with a durable stainless-steel housing, offering protection against dust and water. Along with an audible alarm, the color-changing display shifts during checkweighing mode…

How a Waste Treatment Plan Can Improve Your Bottom Line

Although waste is unavoidable in industrial processes, many companies are turning toward business strategies that seek to treat waste with minimal environmental impact — or even better, prevent waste altogether In the past, waste was simply discharged without any treatment.…
